CASIO 5497 (01) PDF DOCUMENT

Before using your CASIO 5497 watch, it is important to understand the following:

Warning!

• The measurement functions built into this watch are not intended for taking measurements that require professional or industrial precision. Values produced by this watch should be considered as reasonable representations only.

• When engaging in mountain climbing or other activities in which losing your way can create a dangerous or life-threatening situation, always use a second compass to confirm direction readings.

Important!

• The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure readings. This means that readings taken at different times at the same location may produce different altitude values due to changes in barometric pressure. The value displayed may also differ from the actual elevation indicated for your area.

• When using the watch’s altimeter while mountain climbing, be sure to perform regular calibration in accordance with the local altitude (elevation) indications.

• When using the digital compass for serious trekking or other activities, always take along another compass to confirm readings. If the readings from the watch differ from the other compass, perform bidirectional calibration of the digital compass to ensure more accurate readings.

• Direction readings and digital compass calibration will not be possible if the watch is near a permanent magnet, metal objects, high-voltage wires, or electrical household appliances (TV, computer, cellphone, etc.).

The crown of your CASIO 5497 watch is a screw-in lock crown. Before use, you must first rotate it towards you to loosen it. After performing crown operations, press the crown in lightly as you screw it back in.

The different crown operations are:

• Loosen: Rotate the crown towards you.

• Rotate: Turn the crown to change settings.

• Pull out: Pull the crown outwards to a click stop.

• Push in: Push the crown back to its normal position and screw it in by rotating it away from you.

Important! To maintain water resistance and avoid impact damage, always screw the crown back in when you are not using it.

You can use high-speed movement to move watch hands or indicators quickly. There are two types: HS1 and HS2.

To start HS1 high-speed movement:

While the crown is pulled out, rotate it rapidly away from you (forward) or towards you (reverse) until the desired HS1 high-speed movement starts.

To start HS2 high-speed movement:

While HS1 high-speed movement is in progress, again rotate the crown rapidly in the same direction until HS2 high-speed movement starts.

To stop high-speed movement:

Rotate the crown in the direction that is opposite that of the current high-speed movement or press any button.

Note:

• If you do not perform any operation for more than two minutes after pulling out the crown, crown operations will become disabled. If this happens, push the crown back in and then pull it out again to re-enable them.

• High-speed movement can be used when changing time/date settings in Timekeeping Mode, World Time Mode, Countdown Timer Mode, or Alarm Mode, or when performing various calibration operations.

Follow these steps to set up your CASIO 5497 watch for use:

1. Check the battery power level.

Hold down button (D) for at least two seconds to enter the Timekeeping Mode and display the battery power level. If the indicator shows H or M, the watch is charged sufficiently. If L or CHARGE is flashing, the power is low. Charge the watch by placing it in a location where it is exposed to light.

2. Check the Home City and the daylight saving time (DST) setting.

Configure your Home City and daylight saving time settings. Proper World Time Mode data depends on correct Home City, time, and date settings in the Timekeeping Mode.

3. Set the current time.

Configure the current time and date settings. The watch is now ready for use.

To check the battery power level on your CASIO 5497 watch, hold down button (D) for at least two seconds to enter the Timekeeping Mode. The battery power level will be indicated as H (High) or M (Medium) on the left side of the digital display. If the battery power is sufficient, you can proceed to the next step. If the display shows a flashing L or CHARGE, the power is low and the watch needs to be charged.

If you observe any of the following conditions on your CASIO 5497, the battery power is low:

• L is flashing on the digital display.

• CHARGE is flashing on the display.

When power is low, you should charge the watch by placing it in a location where it is exposed to light. When L is flashing, the second hand will jump at two-second intervals. When CHARGE is flashing, all hands will move to and stop at 12 o’clock.

The face of your CASIO 5497 watch is a solar panel that generates power from light, which charges a built-in rechargeable battery. The watch charges whenever it is exposed to light.

Charging Guide:

• Whenever you are not wearing the watch, leave it in a location where it is exposed to light.

• Best charging performance is achieved by exposing the watch to the strongest light available.

• When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing, as this may cause the watch to enter a sleep state.

Warning! Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to conditions like being on the dashboard of a car in direct sunlight, too close to an incandescent lamp, or under direct sunlight.

Important!

• Storing the watch for long periods in an area with no light can cause the power to run down. Expose the watch to bright light whenever possible.

• Turn on the watch’s Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods to help ensure power does not run down.

You can see the power level of your CASIO 5497 by observing the battery power indicator on the display in Timekeeping Mode. The levels and their meanings are as follows:

• The flashing L indicator at Level 3 tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible.

• Once the battery reaches Level 2 (M) after falling to Level 5, you must reconfigure the current time, date, and other settings.

When the battery power on your CASIO 5497 reaches Level 3, the second hand of the watch will jump at 2-second intervals in the Timekeeping Mode to let you know that charging is required.

Performing multiple sensor, illumination, or beeper operations on your CASIO 5497 during a short period may cause the recovery indicator (RECOVER) to flash on the display. This indicates the watch is in power recovery mode. While in this mode, the following functions are disabled until the battery power recovers:

• Illumination

• Alarm

• Countdown timer alarm

• Hourly time signal

• Sensor operations

Battery power will recover in about 15 minutes, at which point the RECOVER indicator will stop flashing, and the listed functions will be enabled again.

Frequent flashing of the RECOVER indicator means that the battery power is low and you should expose the watch to bright light as soon as possible.

The approximate charging times for your CASIO 5497 are as follows. Actual exposure times depend on lighting conditions.

*1: Approximate amount of exposure time required each day to generate enough power for normal daily operation.

*2: Approximate amount of exposure time (in hours) required to take power from one level to the next.

When turned on, the Power Saving feature on your CASIO 5497 automatically enters a sleep state whenever the watch is left for a certain period in a dark area. This helps conserve battery power.

There are two sleep state levels:

• The watch will not enter a sleep state between 6:00 AM and 9:59 PM. However, if it is already in a sleep state at 6:00 AM, it will remain so.

• The watch will not enter a sleep state while it is in the Stopwatch or Countdown Timer Mode, or while barometric pressure change indication is enabled.

To recover from the sleep state:

Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading.

Your CASIO 5497 watch has 10 modes. The mode you should select depends on what you want to do.

You can press the (B) button to navigate between modes on your CASIO 5497 watch. The general sequence is:

Timekeeping Mode -> Barometer Mode -> Thermometer Mode -> Data Recall Mode -> Stopwatch Mode -> Countdown Timer Mode -> Alarm Mode -> World Time Mode -> Timekeeping Mode

Additionally, button operations are provided for direct access to certain modes:

• Press (A) to enter Altimeter Mode.

• Press (C) to enter Digital Compass Mode.

To return to the Timekeeping Mode from any other mode, hold down (C) for about two seconds.

The CASIO 5497 watch automatically returns to the Timekeeping Mode from other modes if the crown is not pulled out or if no button operation is performed for a preset amount of time.

Use the Timekeeping Mode (TIME) on your CASIO 5497 to set and view the current time and date. Each press of the (D) button in the Timekeeping Mode will cycle through the screen contents as shown below:

1. Day of the week, month/day screen

2. Barometric pressure graph, date (month/day) screen

3. Time (hour, minute, second) screen

Follow these steps to configure the Home City and summer time (DST) settings on your CASIO 5497:

1. In the Timekeeping Mode, pull out the crown. “CITY” will flash on the digital display.

2. Rotate the crown to move the second hand to the city code of the city you want to use as your Home City.

3. Press (B) to display the DST setting screen.

4. Rotate the crown away from you to switch between DST off (OFF) and DST on (ON).

5. After the settings are the way you want, push the crown back in.

Note: You cannot switch DST settings while UTC is selected as your Home City. Daylight Saving Time is turned on when the DST indicator is on the display.

To change the current time and date on your CASIO 5497:

1. In the Timekeeping Mode, pull out the crown. This will cause “CITY” to flash.

2. Press (D). This will cause “HOUR-MIN” to flash. The second hand will point to either A (a.m.) or P (p.m.).

3. Rotate the crown to change the minute setting.

4. Press (B). This will cause “HOUR” to flash.

5. Rotate the crown to change the hour setting.

6. Press (B). This will cause the currently set year, month, and day to appear, with the year setting flashing.

7. Rotate the crown to adjust the year setting.

8. Press (B). This will cause the currently set date (month, day) to flash.

9. Rotate the crown to adjust the month and day setting. Pressing (B) again will return to the hour and minute setting screen.

10. After the settings are the way you want, push the crown back in. This will cause timekeeping to start from 0 seconds.

Note: The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except after the watch’s rechargeable battery is replaced or after power drops to Level 5.

To switch between 12-hour and 24-hour time formats on your CASIO 5497:

1. Pull out the crown.

2. Press (B) five times. This causes the current timekeeping setting (12H or 24H) to flash on the digital display.

3. Rotate the crown to select either 12-hour (12H) or 24-hour (24H) timekeeping.

4. After the setting is the way you want, push the crown back in.

If the hands of your CASIO 5497 go out of alignment with the digital display time due to strong magnetism or impact, you can adjust them manually. The watch also adjusts hand alignment automatically periodically.

To adjust home positions manually:

1. In the Timekeeping Mode, pull out the crown.

2. Hold down (A) for at least five seconds until “HAND SET” flashes and then “HAND ADJ” appears on the digital display. Wait until all of the hands move to 12 o’clock.

Important! Before proceeding to step 3, make sure that all hands have returned to the 12 o’clock position. Pushing the crown back in while any hand is not at 12 o’clock will not perform the adjustment.

3. Push the crown back in. This will cause all of the hands (mode, hour, minute, second) to return to their normal positions.

After performing the adjustment, enter the Timekeeping Mode and check to ensure the analog hands and the digital display show the same time. If they do not, perform the adjustment again.

You can use the hand shift feature to temporarily move the analog hands away from the digital display for better viewing.

To shift the hands and view digital info:

While holding down (L), press (B). This will cause all hands to move to 2 o’clock.

To return the hands to their normal positions:

Press any one of the following buttons: (A), (B), (C), or (D).

The hands will also return to their normal positions if you do not perform any operation for about 10 seconds, or when you push the crown back in after pulling it out.

Auto Hand Shift:

If the hour and/or minute hand is over the digital display when an altitude, barometric pressure, or temperature reading is updated, the hand(s) will shift automatically (to 4 o’clock or 8 o’clock) to provide a better view. The hands will return to their normal position after about three seconds.

You can use the Digital Compass Mode on your CASIO 5497 to determine the direction of north and check your bearing to a destination.

1. Make sure the watch is in the Timekeeping, Digital Compass, or Altimeter Mode.

2. Place the watch on a flat surface. If you are wearing it, make sure your wrist is horizontal.

3. Point the 12 o’clock position of the watch in the direction whose reading you want to take.

4. Press (C) to start. “COMP” will appear on the display. The second hand will move momentarily to the 12 o’clock position and then indicate magnetic north.

After the first reading, the watch will continue to take readings automatically each second for up to 60 seconds. The watch will return to the Timekeeping Mode about 60 seconds after the reading operation is complete. To restart a reading, press (C).

You should calibrate the bearing sensor on your CASIO 5497 whenever you feel that the direction readings are off. There are two calibration methods:

• Bidirectional Calibration: This calibrates the bearing sensor in relation to magnetic north. Use this when you want to take readings in an area exposed to magnetic force or if the watch becomes magnetized. It is important to perform bidirectional calibration before using the compass to ensure correct readings.

• Magnetic Declination Correction: With this method, you input a magnetic declination angle (the difference between magnetic north and true north), which allows the watch to indicate true north. You can perform this procedure when the magnetic declination angle is indicated on a map you are using.

To perform a bidirectional calibration on your CASIO 5497:

1. In the Digital Compass Mode, pull out the crown. This will cause “+1” to appear on the digital display, with the up arrow (+) flashing.

2. While keeping the watch horizontal, press (C). “+WAIT” will be shown on the display. If calibration is successful, “OK, Turn180°” will appear, and then “+2” will appear. If “ERR” appears, press (C) again to restart.

3. Rotate the watch 180 degrees.

4. Press (C) again to calibrate the second direction. “+WAIT” will be shown. When calibration is successful, the display will show “OK”.

5. After calibration is complete, push the crown back in.

Precautions: You must use two opposing directions that are 180 degrees opposite each other. Do not move the watch while calibration is in progress. Perform the calibration in an environment similar to where you plan to take readings.

To perform a magnetic declination correction on your CASIO 5497:

1. In the Digital Compass Mode, pull out the crown. This will cause “+1” to appear with an up arrow (+) flashing.

2. Press (B). This will cause “DEC” and the current magnetic declination setting to appear.

3. Rotate the crown to change the magnetic declination direction and angle settings as desired. You can select a value within the range of W 90° to E 90°. The settings are:

• OFF: No correction (declination angle is 0°).

• E: When magnetic north is to the east (east declination).

• W: When magnetic north is to the west (west declination).

To turn off (OFF) magnetic declination correction, press (A) and (C) at the same time.

4. After calibration is complete, push the crown back in.

When using the digital compass feature of your CASIO 5497 watch, please observe the following precautions:

Location:

• Taking a direction reading near a source of strong magnetism can cause large errors. Avoid taking readings near permanent magnets (magnetic necklaces), concentrations of metal (metal doors), high tension wires, and household appliances (TVs, computers, etc.).

• Accurate readings are impossible indoors, especially inside ferroconcrete structures, or while in a train, boat, or airplane.

Storage:

• The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Store the watch away from magnets or any other sources of strong magnetism.

• If you suspect the watch has become magnetized, perform a bidirectional calibration.

Magnetic North and True North:

• The northerly direction can be expressed as magnetic north (indicated by a compass needle) or true north (the location of the North Pole). The difference between them is called “declination”. Keep in mind that magnetic north moves over time.

To specify the measurement units on your CASIO 5497:

1. Make sure the watch is in the mode for the type of unit you want to specify (Altimeter, Barometer, or Thermometer Mode).

2. Pull out the crown.

3. Press (B) as many times as necessary until “UNIT” appears on the digital display.

• For altitude, press (B) three times.

• For barometric pressure and temperature, press (B) once.

4. Rotate the crown to change the unit setting.

5. After the settings are the way you want, push the crown back in.

Important: When TYO (Tokyo) is selected as the Home City, the altitude unit is automatically set to meters (m), the barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These settings cannot be changed.

You can select one of two altitude auto reading intervals on your CASIO 5497:

• 0’05: Readings at one-second intervals for the first three minutes, then every five seconds for approximately the next hour.

• 2’00: Readings at one-second intervals for the first three minutes, then every two minutes for approximately the next 12 hours.

To specify the interval:

1. In the Altimeter Mode, pull out the crown. The current altitude reading will appear.

2. Press (B). “INT” will appear, along with the flashing current interval setting.

3. Rotate the crown to select either five seconds (0’05) or two minutes (2’00).

4. After the setting is the way you want, push the crown back in.

To take altitude readings with your CASIO 5497:

1. Make sure the watch is in the Timekeeping, Digital Compass, or Altimeter Mode.

2. Press (A) to start auto altimeter readings. The current altitude value is displayed in units of 1 meter (or 5 feet).

• The measurement range for altitude is -700 to 10,000 meters (-2,300 to 32,800 feet).

• When you press (A), the second hand may indicate either the seconds of the current time or the altitude differential. Press (D) to toggle between these two functions.

• To restart a reading operation, press (A).

• After you are finished, press (B) to return to the Timekeeping Mode and stop auto altimeter readings.

The altitude tendency graph shows changes in altitude over the past 6 readings while readings are being taken automatically.

To minimize reading error, you should update the reference altitude value on your CASIO 5497 before and during any activity where you take altitude readings. Before starting, look up the altitude of your current location on a map, the Internet, etc.

1. In the Altimeter Mode, pull out the crown. The current altitude reading value will flash.

2. Rotate the crown to change the altitude value in one-meter (or five-foot) increments. Change it to the accurate altitude reading you found.

• You can set the reference altitude value within the range of -3,000 to 10,000 meters (-9,840 to 32,800 feet).

• Pressing (A) and (C) at the same time returns to OFF (no reference altitude value), so the watch will perform conversions based on preset data only.

3. After the setting is the way you want, push the crown back in.

You can select either ±100 meters or ±1,000 meters as the altitude differential measurement range on your CASIO 5497.

To specify the range:

1. In the Altimeter Mode, pull out the crown.

2. Press (B) twice. This will cause “DIFF” to appear, along with the flashing current range setting.

3. Rotate the crown to select either 100 meters (100m) or 1,000 meters (1000m).

4. After the setting is the way you want, push the crown back in.

After specifying an altitude differential start point, you can easily measure the change in altitude between that point and other points on your CASIO 5497.

1. In the Altimeter Mode, ensure an altitude reading is on the display. If not, press (A) to take one.

2. Use contour lines on your map to determine the difference in altitude between your current location and your destination.

3. In the Altimeter Mode, hold down (D) for at least two seconds to specify your current location as the altitude differential start point. “DIFF RESET” and then “RESET” will appear. The second hand will indicate the altitude differential, and ±0 will be displayed.

4. While hiking, compare the altitude difference from your map with the watch’s displayed altitude differential value. For example, if the map shows a difference of +80 meters, you know you are nearing your destination when the watch displays +80 meters.

To manually save an altitude reading on your CASIO 5497:

1. In the Altimeter Mode, check to make sure that an altitude reading is on the display. If not, press (A) to take one.

2. Hold down (A) until “REC” flashes and then stops flashing. This will save the currently displayed altitude reading, along with the time and date, in a manually saved record.

The watch has enough memory to store up to 30 manually saved records. If there are already 30 records, the oldest record will be automatically deleted to make room for the new one.

The CASIO 5497 watch automatically checks and updates the following auto save values as altitude auto measurements are taken in the Altimeter Mode:

• High Altitude (MAX)

• Low Altitude (MIN)

• Total Ascent (ASC)

• Total Descent (DSC)

The MAX and MIN values are updated if a new reading is at least ±15 meters (±49 feet) greater or less than the current MAX or MIN value. Cumulative ascent (ASC) and descent (DSC) values are updated whenever there is a difference of at least ±15 meters (±49 feet) from one reading to the next during an Altimeter Mode session.

Generally, air pressure decreases as altitude increases. Your CASIO 5497 watch bases its altitude readings on International Standard Atmosphere (ISA) values defined by the International Civil Aviation Organization (ICAO). These values define relationships between altitude and air pressure.

Note that the following conditions will prevent you from obtaining accurate readings:

• When air pressure changes because of changes in the weather

• Extreme temperature changes

• When the watch itself is subjected to strong impact

The watch expresses altitudes as relative altitude, which is the difference between the altitudes of two different places. Regular calibration using local altitude (elevation) indications is recommended to maximize accuracy.

To take barometric pressure readings with your CASIO 5497:

Use button (B) to select the Barometer Mode (BARO). “BARO” will appear on the display, and the results will appear after about one second.

• After starting a reading, the watch will take readings every five seconds for the first three minutes, and then every two minutes after that.

• To restart a reading, press (A).

• The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about one hour.

• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg). The measurement range is 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg).

• When you enter the mode, the second hand may indicate either seconds or the barometric pressure differential. Press (D) to toggle between these two functions.

The barometric pressure graph on your CASIO 5497 shows a chronological history of pressure readings.

• The horizontal axis represents time, with each dot standing for two hours. The rightmost dot is the most recent reading.

• The vertical axis represents barometric pressure, with each dot standing for a relative difference of 1 hPa from the adjacent dot.

A rising barometric pressure graph generally indicates that upcoming weather will improve, while a falling graph indicates that upcoming weather will deteriorate.

Your CASIO 5497 watch analyzes past barometric pressure readings and uses an indicator to inform you about significant changes. If a significant change is detected, the watch will beep and display a flashing arrow.

The indicator is not displayed if there has been no noteworthy change in barometric pressure.

To enable or disable the barometric pressure change indicator on your CASIO 5497:

In the Barometer Mode, hold down (D) for at least two seconds. Wait until “INFO” appears on the left side of the display and the current setting (ON or OFF) flashes on the right. Use this screen to enable or disable the indicator.

• When “BARO” is shown on the display, the indicator is enabled.

• When “BARO” is not on the display, the indicator is disabled.

The indicator display will turn off automatically 24 hours after you turn it on, or if the battery power goes low.

If you notice serious errors in the pressure readings, you can calibrate the sensor on your CASIO 5497. Incorrect calibration can result in incorrect readings, so first compare the watch’s readings with another reliable barometer.

1. Take a reading with another measurement device to determine the exact current barometric pressure.

2. Use (B) to enter the Barometer Mode (BARO).

4. Rotate the crown to select either on (DST ON) or off (DST OFF) for the DST setting.

5. After the settings are the way you want, push the crown back in.

Note: You cannot switch between standard time/daylight saving time (DST) while UTC is selected as the World Time City. The DST setting affects only the currently selected time zone.

To swap your Home City and World Time City on your CASIO 5497:

In the World Time Mode, hold down (A) for at least three seconds. After “CITY” flashes on the digital display, the watch will swap the Home City and World Time City settings. The analog hands will move to the current time in the new Home City, and the digital display will show the current time in the new World Time City.

Your CASIO 5497 features an LED light for easy reading in the dark.

To turn on illumination manually:

Press (L) in any mode to illuminate the display.

To change the illumination duration:

1. In the Timekeeping Mode, pull out the crown.

2. Press (B) four times. This will cause “LIGHT” to appear, along with a flashing value (1 or 3).

3. Rotate the crown to select either 1 (1.5 seconds) or 3 (three seconds) for the duration.

4. After the setting is the way you want, push the crown back in.

The auto light switch on your CASIO 5497 turns on illumination automatically when you angle the watch towards your face in the dark.

To enable or disable the auto light switch:

1. In the Timekeeping Mode, pull out the crown.

2. Press (B) three times. This will cause “AUTO” to appear, along with the flashing current setting (ON or OFF).

3. Rotate the crown to select either enabled (ON) or disabled (OFF).

4. Push the crown back in.

The auto light switch turns off automatically whenever battery power drops to Level 4.

Warning! Always make sure you are in a safe place when using the auto light switch. Sudden illumination can startle or distract others. Turn off the auto light switch before riding a bicycle or operating any motor vehicle to avoid distraction and accidents.

To turn the button operation tone on or off on your CASIO 5497:

1. In the Timekeeping Mode, pull out the crown.

2. Press (B) twice. This will cause the current setting (KEY or MUTE) to flash.

3. Rotate the crown to select either on (KEY) or off (MUTE).

4. Push the crown back in.

To turn the Power Saving feature on or off on your CASIO 5497:

1. In the Timekeeping Mode, pull out the crown.

2. Press (B) six times. This will cause “P.SAVE” to appear, along with the flashing current setting (ON or OFF).

3. Rotate the crown to select either on (ON) or off (OFF).

4. Push the crown back in.

If the time on your CASIO 5497 is incorrect, check the following:

• Off by hours: Your Home City setting may be wrong. Check your Home City setting and correct it if necessary.

• Off by one hour: You may need to change your Home City’s standard time/daylight saving time (DST) setting. Use the procedure for changing the current time and date settings to adjust the DST setting.

Relative altitude on your CASIO 5497 is calculated based on changes in barometric pressure. This means that pressure changes can cause readings taken at different times at the same location to be different. The value displayed may also differ from the actual or sea level elevation for your area. When using the altimeter while mountain climbing, you need to perform regular calibration in accordance with local altitude (elevation) indications by specifying a reference altitude value.

If your CASIO 5497 watch indicates abnormal magnetism detection during a direction reading, you should move away from any potential source of strong magnetism and try taking a reading again. If abnormal magnetism is detected again on a retry, it could mean the watch itself has become magnetized. If this happens, continue to keep away from the source of strong magnetism, perform bidirectional calibration, and then try taking a reading again.

An “ERR” message on your CASIO 5497 during sensor operations indicates a problem with the sensor, making readings impossible. This could be due to a sensor malfunction or nearby strong magnetic force.

• If the error is indicated while a reading is in progress, restart the operation. If “ERR” appears again, there might be something wrong with the sensor.

• If “ERR” appears frequently, it could mean the sensor is faulty. Contact your original retailer or a CASIO service center.

• If “ERR” appears following a bidirectional calibration (preceded by hyphens —), wait about one second for it to disappear and then try calibrating again. If “ERR” continues to appear after multiple attempts, contact your retailer or service center.

When TYO (Tokyo) is selected as the Home City on your CASIO 5497, the altitude unit is automatically set to meters (m), the barometric pressure unit to hectopascals (hPa), and the temperature unit to Celsius (°C). These settings cannot be changed while TYO is the Home City.

If the time for your World Time City is off in the World Time Mode on your CASIO 5497, it could be due to incorrect switching between standard time and daylight saving time. Please see “To configure World Time City and summer time settings” to correct the setting.

If your CASIO 5497 watch does not resume operation after being exposed to light, it can be because the power level has dropped to Level 5. You should keep the watch exposed to light until it recharges sufficiently.

If you see a flashing indicator on your CASIO 5497, it means the following:

• RECOVER is flashing: The watch is in the charge recovery mode. This can happen after repeated illumination or sensor operations. Wait until the recovery process is complete (about 15 minutes). The watch will recover more quickly if you place it in a brightly lit location. During this time, access to some functions is limited.

• CHARGE is flashing: This means that the charge level of the watch has suddenly dropped. Immediately expose the watch to light to charge it.

The following city codes and their corresponding UTC offsets are available on the CASIO 5497 watch, based on data as of January 2016.
