    Why Icom IC-M32 Transceiver does not turn ON?
    • S
      Susan SmithAug 23, 2025
      Your Icom Transceiver might not be turning on because the battery is exhausted. In this case, recharge the battery pack. Alternatively, there may be a bad connection to the battery pack; check the connection to the transceiver to resolve this.

    What to do if there is no sound from Icom IC-M32 speaker?
    • T
      Tanya BurtonAug 26, 2025
      If you're not getting any sound from your Icom Transceiver's speaker, there are a few potential causes. First, the squelch level might be set too deep; try setting the squelch to the threshold point. Also, the volume level could be too low, so push the [+]/[–] buttons to adjust it to a suitable level. Finally, if the speaker has been exposed to water, drain the water from the speaker.

    Why is transmitting impossible or high power cannot be selected on my Icom Transceiver?
    • K
      Kelly JacksonAug 28, 2025
      If transmitting is impossible or you can't select high power on your Icom Transceiver, it could be due to several reasons. Some channels are designated for low power or receive only, so try changing channels. Also, check if the battery is exhausted and recharge it if necessary. The battery may be over charged, so verify the battery voltage is correct. Finally, the output power might be set to low; push [H/L•LOCK] to select high power.

    What to do if Icom IC-M32 Transceiver displays self check error related to battery voltage?
    • J
      Jennifer WaltonAug 30, 2025
      If your Icom Transceiver shows a self-check error related to battery voltage, it means that the connected battery pack’s voltage is more than 11 V. Verify that the battery voltage is correct.

    What does it mean when Icom Transceiver displays self check error related to temperature?
    • J
      Joshua LaneSep 1, 2025
      If your Icom Transceiver displays a self-check error related to temperature, it means the temperature is outside of –25°C to +65°C (–13°F to +149°F). Leave the transceiver at room temperature for a while and then turn the power ON to check if the internal temperature has returned to normal.

    • J
      jamiedavisSep 4, 2025
      If you are not hearing any beeps from your Icom Transceiver, the beep tones are likely turned OFF. You can set the beep tones to ON (Fix Beep/User Beep) in SET mode.

    What to do if the displayed channel cannot be changed on Icom IC-M32?
    • J
      John SalinasSep 6, 2025
      If you cannot change the displayed channel on your Icom Transceiver, the lock function is probably activated. Push the [H/L•LOCK] button for 1 second to cancel the function.

    Why Icom IC-M32 Transceiver scan does not start?
    • B
      Brian SantosSep 8, 2025
      If the scan function does not start on your Icom Transceiver, it is possible that “TAG” channels are not programmed. To resolve this, set the desired channels as “TAG” channels.
