CASIO 2767 (01) PDF Document

Congratulations upon your selection of this CASIO watch. To get the most out of your purchase, be sure to carefully read the manual.

Expose the watch to bright light to charge its battery before using it. You can use this watch even as its battery is being charged by exposure to bright light.

The built-in sensors of your CASIO 2767 watch measure direction, altitude, barometric pressure, and temperature. Measured values are then shown on the display. Such features make this watch useful when hiking, mountain climbing, or when engaging in other such outdoor activities.

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 be sure to use a second compass to confirm direction readings.

If the SLEEP indicator is on the display (either flashing or steady), it means that the display is blank because the watch’s Power Saving function has turned off the display to conserve power. Power Saving automatically turns off the display and enters a sleep state whenever the watch is left for a certain period where it is dark.

The watch recovers from the sleep state if you move it to a well-lit area (it can take up to two seconds), if you press any button, or if you angle the watch towards your face for reading.

You can navigate between modes by pressing the D button. The sequence of modes is: Timekeeping Mode -> Alarm Mode -> Data Recall Mode -> Stopwatch Mode -> Hand Setting Mode -> Timekeeping Mode.

From the Timekeeping Mode or another sensor mode, you can use buttons B (Barometer/Thermometer), C (Digital Compass), or E (Altimeter) to directly enter the mode assigned to it. From any other mode, you must go to the Timekeeping Mode first. In any mode, you can press L to illuminate the display.

1. In the Timekeeping Mode, hold down A until the seconds start to flash, which indicates the setting screen.

2. Press C to move the flashing in the following sequence to select other settings: Seconds -> Hour -> Minutes -> 12/24-Hour Format -> Year -> Month -> Day -> Day of week -> Power Saving on/off.

3. When the setting you want to change is flashing, use E (+) or B (-) to change it as described below:

4. Press A to exit the setting screen.

• Resetting the seconds only (without changing the hour or minute setting) causes the analog minute hand setting to be adjusted automatically.

• With the 12-hour format, the P (PM) indicator appears for times from noon to 11:59 p.m.

• The year can be set in the range of 2000 to 2039.

• The watch’s built-in full automatic calendar makes allowances for different month lengths and leap years.

Perform this procedure when the time indicated by the analog hands does not match the time of the digital display.

1. In the Timekeeping Mode, press D four times to enter the Hand Setting Mode.

2. Hold down A until the current digital time starts to flash, which indicates the analog time setting screen.

3. Press E to advance the analog time setting by 20 seconds.

• Holding down E advances the analog time setting at high speed.

• To lock high-speed movement, hold down E until it starts, then press B. High-speed hand movement continues until you press any button. It also stops automatically after 12 hours or if an alarm sounds.

4. Press A to exit the setting screen.

To return to the Timekeeping Mode, press D.

To enter and exit the Digital Compass Mode:

1. While in the Timekeeping, Barometer/Thermometer, or Altimeter Mode, press C to enter the Digital Compass Mode. The watch will start a compass operation, taking readings each second for up to 20 seconds.

2. Press D to return to the Timekeeping Mode.

To take a direction reading:

1. Enter the Digital Compass Mode.

2. Place the watch on a flat surface or ensure your wrist is horizontal.

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

4. Press C to start a Digital Compass measurement operation.

• An angle value and four pointers (north, south, east, west) will appear. The angle value indicates the clockwise angle from magnetic north (0 degrees).

• The — indicator flashes on the display while a measurement is in progress.

Note:

• Taking a measurement while the watch is not horizontal can result in large measurement error.

• Any ongoing direction measurement is temporarily paused during an alert operation (alarm, hourly time signal) or when the backlight is on.

Pressing B in the Timekeeping Mode or any of the other sensor modes enters the Barometer/Thermometer Mode and automatically starts taking measurements. It can take up to four or five seconds for the reading to appear.

You can press B to toggle between a screen showing the history graph and barometric pressure, and a screen showing the temperature and barometric pressure.

• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg). The value changes to —- hPa (or —- inHg) if the reading is outside the range of 260 hPa to 1,100 hPa.

• Temperature is displayed in units of 0.1°C (or 0.2°F). The value changes to –.-°C (or –.-°F) if the reading is outside the range of -10.0°C to 60.0°C.

• Measurements are taken every five seconds for the first three minutes, then every three hours for the history graph.

The barometric pressure history graph contains points showing changes in barometric pressure for up to the last 18 hours. By monitoring these changes, you can predict the weather with reasonable accuracy.

• A rising graph generally means improving weather.

• A falling graph generally means deteriorating weather.

The relative positions of the points on the graph indicate whether barometric pressure is rising (rise greater than 3hPa), falling (fall greater than 3hPa), or holding relatively steady (within ±3hPa).

This watch estimates altitude based on air pressure. This means that altitude readings for the same location may vary if air pressure changes.

• With Preset Values (No Reference Altitude): The watch measures air pressure and uses built-in ISA (International Standard Atmosphere) values to convert it to the equivalent altitude.

• With a Reference Altitude: If you set a reference altitude, the watch uses that value when calculating altitude. When mountain climbing, you can set the reference value from a marker or map for more accurate readings.

Important!

• This watch employs a semiconductor pressure sensor, which is affected by temperature changes. Wear the watch in direct contact with your wrist during measurement to avoid the effect of sudden temperature changes.

• Do not rely upon this watch for altitude measurements that demand professional or industrial level precision.

• The air inside a commercial aircraft is pressurized, so readings will not match the altitude announced by the flight crew.

To take an altitude reading:

Pressing E in the Timekeeping Mode or any other sensor mode enters the Altimeter Mode and starts measurement. It can take up to five seconds for the reading to appear. During the first three minutes, measurements are taken every five seconds. After that, they are taken every two minutes.

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

• If a measured altitude falls outside the range, the display shows —- meters (or feet).

To set a reference altitude:

1. In the Altimeter Mode, hold down A for about two seconds until the watch beeps. After a few seconds, OFF or the current reference altitude value will flash.

2. Press E (+) or B (-) to change the reference altitude value by 5 meters (or 20 feet). You can set it within the range of -10,000 to 10,000 meters.

• Pressing E and B at the same time returns to OFF (no reference altitude).

3. Press A to exit the setting screen.

To store an altitude record:

In the Altimeter Mode, hold down E for about one second until the watch beeps. This stores a record of the current date, time, and altitude. The watch can store up to 41 records. If memory is full, the oldest record is deleted to make room for the new one. A maximum altitude record is also kept separately.

To view altitude record data:

1. Use D to enter the Data Recall Mode. The message RECALL appears, followed by the maximum altitude record.

2. Press E to cycle through the altitude record screens. The maximum altitude record appears first, then records are shown from oldest to newest.

• For each record, the lower display alternates between the recording time and the altitude value.

To delete the maximum altitude record data:

1. In the Data Recall Mode, display the maximum altitude record (the one with MAX next to the time and altitude values).

2. Hold down A for about two seconds. This will delete the data. You can only delete the maximum altitude record, not individual records.

To set the alarm time:

1. In the Alarm Mode (press D), hold down A until the hour setting starts to flash.

2. Press C to move the flashing between the hour and minute settings.

3. While a setting is flashing, use E to increase it. When using the 12-hour format, set the time correctly as a.m. (no indicator) or p.m. (P indicator).

4. Press A to exit the setting screen. This automatically turns on the alarm.

Alarm Operation:

The alarm sounds for about 10 seconds at the preset time. You can stop it by pressing any button.

To test the alarm:

In the Alarm Mode, hold down E to sound the alarm.

To turn the daily alarm and Hourly Time Signal on and off:

In the Alarm Mode, press E to cycle through the settings: Alarm On/Signal Off -> Alarm Off/Signal On -> Alarm On/Signal On -> Alarm Off/Signal Off.

The respective indicators are shown on the display in all modes when these functions are turned on.

All operations are performed in the Stopwatch Mode, which you enter by pressing D. The stopwatch can measure up to 23 hours, 59 minutes, 59.99 seconds.

Elapsed Time:

E (Start) -> E (Stop) -> E (Re-start) -> E (Stop) -> B (Clear)

Split Time:

E (Start) -> B (Split) -> B (Split release) -> E (Stop) -> B (Clear)

Two Finishes:

E (Start) -> B (Split – First runner finishes) -> E (Stop – Second runner finishes) -> B (Split release – Display time of second runner) -> B (Clear)

To turn on the backlight manually:

Press L in any mode to illuminate the display for about two seconds.

About the Auto Light Switch:

Turning on the auto light switch causes the backlight to turn on for about two seconds whenever you position your wrist parallel to the ground and then tilt it towards you more than 40 degrees. This feature only operates when available light is below a certain level.

To turn the auto light switch on and off:

In the Timekeeping Mode, hold down B for about two seconds to toggle the auto light switch on (indicator displayed) or off (indicator not displayed).

Warnings and Precautions:

• Always be in a safe place when reading the display using the auto light switch.

• Turn off the auto light switch before riding a bicycle or operating any other motor vehicle.

• The auto light switch is always disabled during direction measurement or when the Hand Setting screen is displayed.

• Static electricity or magnetic force can interfere with proper operation.

Incorrect direction readings:

This can be caused by incorrect bidirectional calibration, or a nearby source of strong magnetism (e.g., household appliance, steel bridge, overhead wires). Move away from large metal objects and try again. Digital compass operation cannot be performed inside a train, boat, etc.

Different results at the same location:

Magnetism from nearby high-tension wires can interfere with detection of terrestrial magnetism. Move away from the wires and try again.

Problems taking readings indoors:

A TV, computer, speakers, or other object can interfere with readings. Move away from the object or take the reading outdoors. Readings are particularly difficult inside ferro-concrete structures.

Generally, air pressure and temperature decrease as altitude increases. The watch bases its altitude measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil Aviation Organization (ICAO), which define relationships between altitude, air pressure, and temperature.

Note that readings can be affected by changes in air pressure due to weather, extreme temperature changes, or if the watch is subjected to strong impact.

Altitude and temperature measurements require different conditions for best results.

• To give altitude measurement priority, leave the watch on your wrist. This keeps the watch at a constant temperature, which contributes to more accurate altitude measurements.

• To give temperature measurement priority, remove the watch from your wrist and allow it to hang freely where it is not exposed to direct sunlight. This eliminates the effects of body heat. Note that removing the watch can momentarily affect pressure sensor readings.

The battery power indicator on the display shows the current status of the rechargeable battery’s power.

• At Level 4, all functions are disabled and settings return to their initial factory defaults. You need to set the time and date after the battery reaches Level 2 from Level 4.

• If you use the backlight or alarm multiple times in a short period, RECOV may appear on the display, temporarily disabling the backlight, alarm, and sensor operations until the battery power recovers.

Charge Times (for daily operation)

Recovery Times (to move from one level to the next)

These values are for reference only. Actual required exposure times depend on lighting conditions.

Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Allowing the watch to become very hot can cause its liquid crystal display to black out, which should return to normal when the watch cools.

Warning! Leaving the watch in bright light to charge 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 the following conditions for long periods:

• On the dashboard of a car parked in direct sunlight

• Too close to an incandescent lamp

• Under direct sunlight

Should the pressure sensor or direction sensor malfunction, the message ‘Err’ appears on the display for about two seconds, and then sensor operation is disabled.

• If ‘Err’ appears while a measurement operation is being performed, restart the measurement. If ‘Err’ appears again, it may indicate a sensor problem.

• Even with sufficient battery power (Level 1 or 2), the ‘Err’ message can appear if there is not enough voltage to power the sensor sufficiently. This does not indicate a malfunction, and operation should resume once voltage returns to normal.

• The message may appear momentarily if you exit a sensor mode while a measurement is in progress. This is normal.

If you experience a persistent sensor malfunction, take the watch to your original dealer or an authorized CASIO distributor.

When turned on, the Power Saving function automatically puts the watch into a sleep state when it is left for a certain period in a dark area.

• The watch will not enter the sleep state between 6:00 AM and 9:59 PM, or while in the Digital Compass, Barometer/Thermometer, Altimeter, or Stopwatch modes.

To recover from the sleep state:

• Move the watch to a well-lit area.

• Press any button.

• Angle the watch towards your face for reading.

To turn Power Saving on and off:

1. In the Timekeeping Mode, hold down A until the seconds flash.

2. Press C eight times until the Power Saving on/off screen appears.

3. Press E to toggle Power Saving on (ON) and off (OFF).

4. Press A to exit the setting screen.

You should calibrate the bearing sensor whenever you suspect direction readings are wrong. You can use bidirectional calibration or northerly calibration. If you perform both, do bidirectional calibration first.

To perform bidirectional calibration:

1. In the Digital Compass Mode, hold down A for about one second until -1- appears.

2. Place the watch on a level surface facing any direction and press C to calibrate the first direction. “—” appears, then changes to -2- when complete.

3. Rotate the watch 180 degrees.

4. Press C again to calibrate the second direction. “—” appears, and then the normal compass screen appears when calibration is complete.

To perform northerly calibration:

1. In the Digital Compass Mode, hold down A for about one second until -1- appears.

2. Press B to start the northerly calibration procedure. -N- (north) appears.

3. Place the watch on a level surface with its 12 o’clock position pointing north (as measured with another compass).

4. Press C to start the calibration operation. The normal compass screen with 0° appears when complete.

If “Err” appears during calibration, there may be something wrong with the sensor. Press A to exit and try again.

The sensors are calibrated at the factory and normally do not require further adjustment. If you notice serious errors, you can calibrate them. Incorrectly calibrating can result in incorrect readings.

To calibrate the temperature sensor:

1. Remove the watch from your wrist and wait 20-30 minutes for it to stabilize.

2. In the Barometer/Thermometer Mode, hold down A until OFF or the current temperature value flashes in the upper part of the display.

3. Use E (+) or B (-) to change the displayed temperature by 0.1°C (or 0.2°F). Pressing E and B at the same time returns to the factory calibration (OFF).

4. Press A to exit.

To calibrate the barometric pressure sensor:

1. Compare readings with another reliable and accurate barometer.

2. In the Barometer/Thermometer Mode, hold down A until the temperature setting flashes in the upper display.

3. Press C to move the flashing to the pressure sensor calibration setting (lower display).

4. Use E (+) or B (-) to change the displayed barometric pressure by 1 hPa (0.05 inHg). Pressing E and B at the same time returns to the factory calibration (OFF).

5. Press A to exit.

To change the barometric pressure and temperature units:

1. Press B to enter the Barometer/Thermometer Mode.

2. Hold down A until the temperature calibration setting appears.

3. Press C to cycle through the settings: Temperature Calibration -> Pressure Calibration -> Temperature Unit (°C/°F) -> Pressure Unit (hPa/inHg).

4. When the unit setting you want to change is flashing, use E to select the unit you want.

5. Press A to exit.

To change the altitude unit:

1. Press E to enter the Altimeter Mode.

2. Hold down A for about two seconds until the reference altitude setting appears.

3. Press C to move the flashing to the altitude unit setting (m or ft).

4. Use E to select the unit you want (m or ft).

5. Press A to exit.
