ICOM IC-M510 (01) PDF Document

If your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on Channel 16.

1. Push [16/C] to switch to Channel 16.

2. While holding down [PTT], provide the following information:

• “MAYDAY MAYDAY MAYDAY.”

• “THIS IS [name of vessel].”

• Say your call sign or other indication of the vessel (AND your 9 digit DSC ID, if you have one).

• “LOCATED AT [your position].”

• State the nature of the distress and assistance required.

• Give any other information which might facilitate the rescue.

You can transmit a Distress call using Digital Selective Calling (DSC) on Channel 70.

1. Lift up the key cover and hold down [DISTRESS] for 3 seconds until you hear 3 short beeps and then one long beep.

2. Wait for an acknowledgment from another station.

3. After the acknowledgment is received, Channel 16 is automatically selected.

4. Hold down [PTT], then transmit the appropriate information as you would for a Channel 16 distress call.

• WARNING! NEVER connect the transceiver directly to an AC outlet. This may cause a fire or an electric shock.

• WARNING! NEVER connect the transceiver to a power source of more than 16 V DC, such as a 24 V battery. This could cause a fire or damage the transceiver.

• WARNING! NEVER reverse the DC power cable polarity. This could cause a fire or damage the equipment.

• WARNING! NEVER cut the DC power cable between the DC power connector and the fuse holder. An incorrect connection may damage the transceiver.

• WARNING! NEVER operate the transceiver during a lightning storm. Always disconnect the power source and antenna before a storm.

• WARNING! NEVER place the transceiver where normal operation of the vessel may be hindered, or where it could cause bodily injury.

• CAUTION: DO NOT place or leave the transceiver in areas with temperatures below –20°C (–4ºF) or above +60°C (+140ºF), or in areas subject to direct sunlight.

• CAUTION: DO NOT use harsh solvents such as Benzine or alcohol when cleaning. If the surface becomes dusty or dirty, wipe it clean with a soft, dry cloth.

• NEVER place the transceiver in an insecure place to avoid inadvertent use by unauthorized persons.

• BE CAREFUL! The transceiver’s rear panel will become hot when transmitting continuously for long periods.

• BE CAREFUL! The transceiver meets IPX8 requirements for waterproof protection. However, if the transceiver or microphone is dropped or the waterproof seal is damaged, waterproof protection cannot be guaranteed.

• NOTE: Install the transceiver and/or microphone more than 1 meter from the vessel’s magnetic navigation compass.

Precautions on using the wireless LAN:

• It is recommended that users with pacemakers take precautions to ensure this device does not cause them a problem due to electromagnetic interferences.

• Do not use this device near microwave ovens. A microwave oven may cause electromagnetic interference to communications.

• Do not modify the device. The device warranty does not cover problems caused by unauthorized modification.

Wireless LAN installation location considerations:

• Install the device in a stable place, free from falling or vibration dangers.

• Do not place anything on top of the device.

• The communication range is best in open space. Metallic walls may cause radio waves to reflect. Radio waves may pass through a wall or window but not through metal.

• Communication may not be possible with a wireless LAN installed on a different floor.

• Install the transceiver within approximately 15 meters from the CT-M500 or an existing access point, with no obstacles between them.

CLEAN THE TRANSCEIVER AND MICROPHONE THOROUGHLY WITH FRESH WATER after exposure to saltwater, and dry it before operating. Otherwise, the transceiver’s keys and switches may become unusable due to salt crystallization.

NOTE: If the transceiver’s waterproof protection appears defective, carefully clean it with a soft, damp (fresh water) cloth, then dry it before operating.

When the connection is successful, the mobile device icon is displayed at the top of the ICOM IC-M510 screen.

If the fuse blows or the transceiver stops functioning, track down the source of the problem, repair it, and then replace the damaged fuse with a new one of the proper rating.

The fuse is installed in the supplied DC power cable. The correct fuse rating is:

• Fuse Coding: F 250 V 10 A

• Fuse Voltage Rating: 250 Volts

• Fuse Current Rating: 10 Amperes

CAUTION: Keep the transceiver and microphone at least 1 meter (3.3 ft) away from the vessel’s magnetic navigation compass.

1. Mount the bracket securely to a surface that is more than 10 mm thick and can support more than 5 kg, using the 4 supplied screws (5 × 20 mm).

2. Attach the transceiver to the bracket so that the face of the transceiver is at a 90° angle to your line of sight for optimal viewing. You can adjust the display angle for readability.

If your ICOM IC-M510 does not turn ON, please check the following:

• Bad connection to the power supply: Check the connection to the transceiver and the power supply.

• The fuse is blown: Repair the source of the problem, and then replace the fuse.

If there is little or no sound from the speaker, check these settings:

• The squelch level is set too high: Set the squelch to the threshold point by rotating the [SQL] dial.

• The volume level is set too low: Set the volume level to a suitable level by rotating the [VOL] dial.

If you cannot transmit on high power, consider the following:

• Some channels are set for low power or receive-only by regulations: Change to a different channel that allows high power transmission.

• The output power is set to low: Push the [H/L] key on the microphone to select high power.

If the scan does not start, it is likely because there are not enough Favorite channels set.

• You must have more than 2 favorite channels set for a scan to start. Set at least 2 favorite channels.

If you see “No Position” and “No Time” on the display, check these possibilities:

• The GPS signal is not correctly received: Check the GPS antenna connection and position. Ensure the transceiver is located where the built-in GPS has a clear view to receive signals from satellites.

• The position and time have not been manually entered: Enter the position and time manually if a GPS signal is unavailable.

If the transceiver has locked up, a software error may have occurred.

• Turn OFF the transceiver, and then turn it ON again to reset it.

If you are having trouble connecting to a CT-M500 or mobile devices via WLAN, check the following:

• The WLAN function is OFF: Turn ON the WLAN function in the menu.

• SSID is set incorrectly: Check the SSID on both the transceiver and the access point to ensure they match.

• CT-M500 has a bad power connection: Check the connection to the CT-M500 and its power supply.
