Why does the noise cancellation not work on my Icom IC-M35?
If the noise cancellation feature isn't working on your Icom Transceiver, it might be because the sub-microphone is covered. Make sure the sub-microphone is not covered. Also, disconnect any optional external speaker-microphones, as they can interfere with the noise cancellation.
How to unlock channel change on Icom Transceiver?
If the displayed channel on your Icom Transceiver cannot be changed, the lock function may be activated. To cancel this function, push and hold the [Hi/Lo] button for 1 second.
What to do if there is no sound from the Icom IC-M35 Transceiver speaker?
If your Icom Transceiver has no sound coming from the speaker, there could be a few reasons. First, the squelch level might be too high; try setting it to the threshold level. Second, the volume level could be too low; adjust it to a suitable level. Finally, if the speaker has been exposed to water, drain the water from it.
What causes a battery voltage error on an Icom IC-M35 Transceiver?
If you are getting a battery voltage error on your Icom Transceiver, it might be because the connected battery pack’s voltage is more than 11 V. Ensure that the battery voltage is correct.
Why won't my Icom IC-M35 start scanning?
If scan does not start on your Icom Transceiver, it may be because “TAG” channels are not programmed. To fix this, set the desired channels as “TAG” channels.
How to enable beep sounds on Icom IC-M35?
If your Icom Transceiver makes no beep sounds, the beep tone function may be turned OFF. To resolve this, set the beep tone function to ON (Fix Beep/User Beep) in the set mode.
Why is noise cancellation not working on my Icom IC-M35?
If the noise cancellation feature isn't working on your Icom Transceiver, ensure that the sub-microphone is not covered. Also, disconnect any optional external speaker-microphones that are connected.
What to do if Icom Transceiver can't transmit or select high power?
If transmitting is impossible or high power cannot be selected on your Icom Transceiver, it may be due to several reasons. Some channels are for low power or receive only, so try changing channels. Also, the battery could be exhausted, so recharge it. Ensure the battery voltage is correct, as an overcharged battery can cause this issue. Lastly, the output power might be set to low; push the [Hi/Lo] button to select high power.
Why does my Icom IC-M35 Transceiver have no sound?
If no sound is coming from the Icom Transceiver's speaker, there are a few potential causes. First, the squelch level may be too high; try setting it to the threshold level. Second, the volume level may be too low; adjust it to a suitable level. Finally, if the speaker has been exposed to water, drain the water from the speaker.
