Why is there no sound from my Icom IC-M411 Transceiver speaker?
If you can't hear any sound from the Icom Transceiver's speaker, there might be a few reasons: * The squelch level could be too high. Try adjusting the [SQL] to the appropriate threshold. * The volume might be set too low. Increase the [VOL] to a suitable level. * The speaker may have been exposed to water. If so, drain the water from the speaker.
How to fix an Icom IC-M411 Transceiver that does not turn on?
If your Icom Transceiver isn't turning on, the issue might be a bad connection to the power supply. Check the connection to the transceiver to ensure it is properly connected.
What to do if Icom IC-M411 Transceiver transmitting is impossible?
If you're unable to transmit or select high power on your Icom Transceiver, it could be due to a couple of reasons: * Some channels are designated for low power or receive-only. Try changing to a different channel. * The output power might be set to low. Press the [HI/LO] button on the microphone to select high power.
Why distress call cannot be transmitted on Icom IC-M411 Transceiver?
If a distress call cannot be transmitted from your Icom Transceiver, the MMSI (DSC self ID) code may not be programmed. Program the MMSI (DSC self ID) code into the transceiver.
Why does scan not start on my Icom IC-M411?
If the scan function on your Icom Transceiver isn't starting, it's possible that no TAG channel is programmed. Set the desired channels as TAG channels to resolve this.
How to enable beeps on Icom IC-M411 Transceiver?
If you are not hearing any beeps from your Icom Transceiver, the beep tones may be turned OFF. Turn the beep tone ON in Set mode.
