What to do if my Radio Shack 20-163 does not function?

If your Radio Shack Scanner is not functioning, ensure the AC or DC adapter is properly connected. The adapter's barrel plug should be fully inserted into the PWR jack, with the center tip set to positive. If using a DC adapter, unplug it from the power source and clean the socket. Also, check the adapter’s internal fuse.
