      Anne WrightAug 1, 2025
      If your CountyComm Receiver isn't turning on, the issue might be due to dead batteries. Try replacing them with new ones. Another possibility is that the batteries are not correctly installed; double-check the polarity and reinstall them. Also, ensure the power button isn't locked; if it is, unlock it by pressing the appropriate button.

      If your CountyComm Receiver shuts off while you're listening, it could be due to dead batteries, so try replacing them. Alternatively, the sleep timer may be activated. If so, simply turn the radio on again.

    What to do if CountyComm Receiver alarm makes noise instead of playing the radio?
    • M
      Michael MatthewsAug 11, 2025
      If your CountyComm Receiver alarm produces only noise, it may be because you haven't properly set the radio station for the alarm. Make sure to preset your alarm station correctly. Also, verify that the radio station is currently broadcasting in your location. As an alternative, you can set the alarm to use the buzzer instead.

    Why can't my CountyComm GP-5 store some stations using ATS?
    • M
      Megan MirandaAug 15, 2025
      If your CountyComm Receiver can't store some stations using ATS, or stores them with noise, the stations might be too weak. Try searching for the station manually. Another cause may be interference in your area. In this case, move to another location and try again.

    How to improve AM reception on CountyComm Receiver in USA?
    • C
      Christine BernardAug 20, 2025
      If you're experiencing poor AM broadcast reception on your CountyComm Receiver in the USA, it's likely because the USA uses a 10kHz step for AM. To resolve this, turn off the radio and press the [9/10kHz] button to select 10kHz.

    Why can my CountyComm GP-5 only receive limited FM stations in Japan?
    • J
      James LeonardAug 27, 2025
      If your CountyComm Receiver is only receiving limited FM stations in Japan, it's because the FM frequency range is 76~90MHz there. To fix this, turn off the radio and long-press the [FM SET] button, then quickly press the [FM SET] button again to select 76~108MHz.
