RESETTING THE SCANNER

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

CAUTION:  This procedure clears all the information you have programmed
          into the scanner.  Before you reset the scanner, try turning it
          off and on to see if it begins working properly.  Use the
          following procedure only when you are sure your scanner is not
          working properly.

1.  Turn off the scanner.

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