I have looked through the manual and still can't find how to reset the scanner. I think I programmed it the wrong way so now when it's tuned into any frequency. You can listen to it through the speaker and it'll play on for about 4 seconds, then pause and totally go silent for about 3. When I received this it didn't do it, but now that I programmed it, it does. I guess I just won't program it and just put the frequency in and just keep that saved.
