What to do if there is no sound from the speaker of Icom IC-GM1600?
- B
  Barry BurtonAug 22, 2025
  If you are unable to hear any sound from the speaker of your Icom Two-Way Radio, there are several potential causes. First, the squelch level might be set too deep; try setting the squelch to the threshold point. Second, the volume level could be too low; rotate the [VOL] control to adjust it to a suitable level. Third, the speaker may have been exposed to water; drain any water from the speaker. Finally, water might have entered the [MIC/SP] connector; ensure that the connector is dry.
