What to do if no sound comes from the Icom Receiver speaker?
If you are not getting any sound from the Icom Receiver's speaker, first, ensure the volume isn't too low by rotating the [R-DIAL] or pushing [Y] to adjust it. Also, check if the squelch level is set too high by pushing [SQL] and rotating [R-DIAL] to adjust the squelch level. Finally, if using tone squelch, verify that the correct tone is selected and turn the function OFF if needed.
How to fix an Icom Receiver that won't power on?
If your Icom Receiver isn't powering on, the batteries may be exhausted. Try replacing them or charging the battery pack. Also, ensure that the battery polarity is correct when inserting them.
