SOURCE: how to program radio shack pro 82 scanner

is it a digital scanner? You know that everyone has gone digital there fore making that kind of scanner outdated and if you are trying to listen to police u wont pick anything up. I was told that some raido shacks will re program it for you.

Turn it on, and when "Welcome" appears, press zero, then press one. It will display a message indicating it is initializing to the factory state.

• Turn the scanner on.
• Press "0"
• Press "1"
• Press "ENT"
• Now press any key
• Now press any key again.

• Somewhere along the line you programmed a talk group into your scanner that does not have any association with any trunking system and your scanner did not like it. You can either find the codes and erase them individually or the hard reset (reset to factory default) by following the steps above.
