Why Icom IC-450 cannot change the operating channel?
If you cannot change the operating channel on your Icom Transceiver, it might be due to the lock function being activated. Hold down for 2 seconds to turn OFF the Lock function. Alternatively, priority scan might be paused on the watching frequency; push to cancel the scan.
How to fix Icom IC-450 Transceiver when the power will not turn ON?
If your Icom Transceiver's power won't turn on, first check the connector pins for poor contact. If that's not the issue, ensure the power connection polarity is correct by reconnecting the power cable properly. Finally, inspect the fuse; if it's blown, identify and fix the cause before replacing it.
What to do if no sound is heard from the Icom IC-450 Transceiver speaker?
If you can't hear any sound from your Icom Transceiver's speaker, first, ensure the volume isn't set too low by pushing . Next, verify that the volume level isn't set to 0 (audio muting) by pushing . Also, check if the squelch is set too high and adjust it to the threshold. Lastly, confirm that a selective call or squelch function, like pocket beep or tone squelch, isn't activated and turn it off if it is.
How to improve sensitivity on Icom IC-450 if only strong signals are audible?
If the sensitivity of your Icom Transceiver is low, and you can only hear strong signals, the antenna feedline or connector may have poor contact or be shorted. Inspect the feedline and connector, and if necessary, replace the feedline or resolder the antenna connector.
Why does scan not start on Icom IC-450?
If the scan function on your Icom Transceiver does not start, it could be because the squelch is open. Try setting the squelch to the threshold point. Another possible reason is that priority scan is activated; in this case, cancel the scan.
