How to unlock frequency change on Icom IC-A14?
If the operating frequency or memory channel on your Icom Transceiver can't be changed, the lock function may be activated. Hold down [ ] for 2 seconds to turn the Lock function OFF.
Why Icom Transceiver won't turn on?
Your Icom Transceiver might not be turning on because the battery is exhausted. In that case, recharge the battery pack. Alternatively, there may be a bad connection for the battery pack. Check the connection to the transceiver to ensure it is properly connected.
What to do if Icom IC-A14 Transceiver has no sound?
If there is no sound coming from the speaker of your Icom Transceiver, it could be due to a squelch level that is too deep. Try setting the squelch to the threshold point. Also, check if the volume level is too low and set the [VOL] to a suitable level.
Why Icom IC-A14 scan does not start?
The scan function on your Icom Transceiver might not start for several reasons: - All memory channels in the selected bank are not programmed as “TAG” channels. Set the “TAG” settings of desired channels. - The squelch is open. Adjust the squelch level to tighten it. - There are not more than 2 memorized channels. Program 2 or more memory channels.
How to fix Icom IC-A14 transmitting impossible issue?
If you are unable to transmit with your Icom Transceiver, it may be because WX channels or the NAVI band is selected. Set the COM band in frequency mode. Also, ensure that the battery is not exhausted by recharging the battery pack.
How to turn on beep sound on Icom IC-A14 Transceiver?
If there are no beep sounds on your Icom Transceiver, it is possible that the beep tones are turned OFF. To turn them ON: - For IC-A14: Push [FUNC], then push [BEEP](8). - For IC-A14S: Turn the beep tone ON in set mode.
Why is my Icom Transceiver not transmitting?
If your Icom Transceiver isn't transmitting, it might be because a WX channel or the NAVI band is selected. Switch to COM band in frequency mode. Also, check if the battery is exhausted and recharge it if necessary.
How to fix no sound from the Icom IC-A14 speaker?
If you're not getting any sound from your Icom Transceiver's speaker, the squelch level might be set too deep. Try adjusting the squelch to the threshold point. Also, make sure the volume isn't too low by adjusting the [VOL] to a suitable level.
What to do if my Icom Transceiver won't turn on?
If your Icom Transceiver won't power on, the battery may be exhausted; try recharging it. Also, ensure the battery pack has a good connection by reattaching it to the transceiver.
