Sound does not work

1 comments:
Mr. Anderson
February 10, 2025

The sound might not work on the Icom IC-M72 due to the following reasons:

1. Squelch Level: The squelch level may be set too high, which blocks audio. Adjust it by pushing the appropriate buttons (`[ ]`, `[Y]`/`[Z]`) to lower the squelch level.

2. Volume Setting: The volume may be set too low. Rotate the `[VOL]` knob to increase the volume.

3. Signal Reception: Ensure the radio is receiving a signal. The " " indicator should appear when a signal is being received, and audio should emit from the speaker.

4. Speaker Issue: Check if the speaker is functioning properly. If the external speaker or audio output is faulty, repair or replacement may be needed.

5. Incorrect Channel: Verify that the correct channel is selected, as some channels may not have active transmissions.

If these adjustments do not resolve the issue, further inspection or servicing may be required.
