    What to do if there is no sound from the Icom IC-M324G speaker?
    • C
      Charles PageAug 4, 2025
      If you experience little or no sound from the Icom Transceiver's speaker, there are several potential causes. First, the squelch level might be set too high; try setting the squelch to the threshold point. Second, the volume level could be too low; adjust the volume to a suitable level. Finally, if the speaker has been exposed to water, use the AquaQuake function to remove it.

      Diana KnightAug 8, 2025
      If your Icom Transceiver does not turn on, the cause might be a bad connection to the power source. Check the connection to both the transceiver and the power source to ensure they are properly connected.

    Why Icom IC-M324G transmitting is impossible?
    • J
      Jennifer LopezAug 13, 2025
      If transmitting is impossible or high power cannot be selected on your Icom Transceiver, it could be due to a couple of reasons. Some channels might be restricted to low power or receive only by regulations, so try changing channels. Alternatively, the output power might be set to low; push the [HI/LO] button to select high power.

      Sarah HuntAug 17, 2025
      If distress calls cannot be transmitted on your Icom Transceiver, the cause might be that the MMSI (DSC self ID) code is not entered. Enter the MMSI (DSC self ID) code to resolve this issue.

    Why is Icom IC-M324G Transceiver GPS receiver not receiving valid position data?
    • M
      Matthew WolfeAug 21, 2025
      If the built-in GPS receiver in your Icom Transceiver (IC-M323G and IC-M324G models only) is not receiving valid position data, it may be because the built-in GPS antenna is covered by an object that interrupts the GPS signals from the satellites. Mount the transceiver in a location where no objects interrupt the satellite signal.

    • M
      Mr. Robert MendezAug 26, 2025
      If the scan function does not start on your Icom Transceiver, it might be because favorite channels are not entered. Set the desired channels as favorite channels to enable the scan function.

    How to turn on beep sounds on Icom Transceiver?
    • D
      Diamond JohnsonAug 29, 2025
      If there are no beep sounds on your Icom Transceiver, it is likely that the beep tones are turned OFF. Turn ON the beep tones in the CONFIGURATION menu to restore the beep sounds.
