RESETTING THE SCANNER

If the scanner's display locks up or does not work properly after you
connect power, you might need to reset the scanner.

CAUTION:  This procedure clears all the information you have stored into
          the scanner (such as frequencies and car numbers).  Before you
          rest the scanner, try turning it off and on to see if it begins
          working properly.  Reset the scanner only when you are sure it
          is not working properly.

1.  Turn off the scanner.

2.  While you hold down the 2 and 9 keys, turn on the scanner.

If you still have problems after resetting the scanner, take it to your
local RadioShack store.
