Why distress calls cannot be transmitted on Icom IC-M424?
If distress calls cannot be transmitted from your Icom Transceiver, the MMSI (DSC self ID) code has not been entered. Enter the MMSI (DSC self ID) code into the transceiver.
Why Icom Transceiver transmitting is impossible?
If you cannot transmit or select high power on your Icom Transceiver, it may be due to the following reasons: 1. Some channels might be restricted to low power or receive-only due to regulations. Try changing to a different channel. 2. The output power may be set to low. Push the [HI/LO] button to select high power.
What to do if distress calls cannot be transmitted on Icom IC-M424 Transceiver?
If distress calls cannot be transmitted on your Icom Transceiver, it is likely because the MMSI (DSC self ID) code has not been entered. Enter the MMSI (DSC self ID) code to resolve this issue.
Why Icom Transceiver scan does not start?
If your Icom Transceiver scan does not start, it could be because no favorite channels have been entered. Set the desired channels as favorite channels to enable the scan function.
What to do if Icom IC-M424 Transceiver displays 'NO POSITION' and 'NO TIME'?
If “NO POSITION” and “NO TIME” are displayed on your Icom Transceiver instead of the actual position and time, this indicates that the GPS signal is not being received correctly. Try mounting the transceiver in a location where no objects obstruct the satellite signal. Alternatively, the position and time may not have been manually entered; in this case, enter the position and time manually.
How to enable beep sounds on Icom IC-M424?
If there are no beep sounds on your Icom Transceiver, the beep tones are likely turned OFF. To resolve this, turn ON the beep tones in the CONFIGURATION menu.
Why Icom Transceiver cannot transmit distress calls?
If you're unable to transmit distress calls with your Icom Transceiver, the MMSI (DSC self ID) code might not be programmed. Program the MMSI (DSC self ID) code to enable distress call transmission.
What to do if Icom Transceiver has no sound?
If you're experiencing little to no sound from your Icom Transceiver's speaker, there are a few potential causes. First, the squelch level might be set too high; try setting the squelch to the threshold point. Alternatively, the volume level could be set 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.
What does 'NO POSITION' and 'NO TIME' mean on Icom Transceiver?
If your Icom Transceiver displays “NO POSITION” and “NO TIME” instead of the position and time (for IC-M423G, IC-M423GE, and IC-M424G models only), this indicates that the GPS signal is not being received correctly. Ensure the transceiver is mounted in a location where no objects obstruct the satellite signal. If that doesn't work, you may need to manually enter the position and time.
Why does scan not start on Icom IC-M424 Transceiver?
If your Icom Transceiver's scan function doesn't start, it might be because you haven't entered any favorite channels. Set the channels you want to scan as favorite channels, and then try starting the scan again.
