      If you're not getting any sound from your GENASYS Radio, there are a few things to check. Ensure that the channel setting on the transmitter matches the receiver. Verify that the transmitter is powered on and transmitting, and if the signal seems weak, try reducing the distance between the transmitter and receiver. Also, make sure the transmitter isn't muted by pressing the MUTE button. As a last resort, try cycling the transmitter’s power.

      Nicole SmithAug 21, 2025
      Sound interruptions or noise in your GENASYS Radio can be due to several reasons. If multiple transmitters are set to the same channel, reconfigure the channel on the transmitter and receiver. Avoid using adjacent channels; instead, use a channel at least two channels apart from any other channel in use. Also, ensure that the channel setting on the transmitter is the same as on the receiver.

    Why do GENASYS LRAD Radio batteries drain quickly?
    • M
      mathew04Aug 25, 2025
      If the batteries in your GENASYS Radio are draining quickly, consider these factors: if the batteries are old, replace them with new ones. Using alkaline batteries is recommended, as manganese batteries have a significantly shorter lifespan. Also, cold conditions can cause batteries to drain faster, so avoid or leave cold environments.
