How to fix an Icom IC-M45A Transceiver that won't turn on?
If your Icom Transceiver shows no power, first ensure the power cord is properly connected. If it is, check the fuse. If the fuse is blown, check the polarity of the power connection and then replace the fuse.
Why is my Icom Transceiver's sensitivity so low?
If the sensitivity of your Icom Transceiver is low, and only strong signals are audible, it could be due to the [SQUELCH] being rotated too far clockwise. Try rotating the [SQUELCH] counterclockwise to a suitable position. Also, inspect the antenna feedline or the antenna connector solder for poor contact or short circuits. If necessary, replace the feedline or resolder the antenna connector.
How to restore sound to my Icom IC-M45A speaker?
If you cannot hear any sound from the speaker of your Icom Transceiver, the [SQUELCH] may be rotated too far clockwise. Rotate the [SQUELCH] counterclockwise to a suitable position.
What to do if my Icom Transceiver won't transmit?
If your Icom Transceiver does not allow transmitting or selecting high power, it may be because transmission is restricted on the current channel. Try changing to a different channel.
Why won't my Icom IC-M45A scan?
If your Icom Transceiver's scan function doesn't start, it might be because no channels are programmed as “TAG” channels. Set the channels you want to scan as “TAG” channels.
How to turn on the backlight on an Icom IC-M45A Transceiver?
If there is no display backlighting on your Icom Transceiver, the backlight function may be turned OFF. While pushing [H/L • DIM], push [UP]/[DN] to select the desired brightness.
Why does my Icom IC-M45A have no beep sound?
If no beeps sound when you push a switch on your Icom Transceiver, the beep function is likely turned OFF. Set beeps to ON in SET mode.
