If you aren't sure what programming options are in your scanner, or you've
changed some options and want to restore the scanner to factory default settings,
first scan the Remove Custom Defaults bar code, then scan Activate Defaults.
This resets the scanner to the factory default settings.
Remove Custom Defaults
Activate Defaults
Note: If using a cordless system, scanning the Activate Defaults bar code also causes both
the scanner and the base or Access Point to perform a reset and become unlinked.
The scanner must be placed in its base to re-establish the link before any setup codes
are entered. If using an Access Point, the linking bar code must be scanned. See
Cordless System Operation: Xenon 1902g/1912 and Granit 1911i/1981i beginning
on page 43,or Cordless System Operation: Xenon 1902g-BF beginning on page 81
for additional information.
The Menu Commands, beginning on page 272, list the factory default settings for
each of the commands (indicated by an asterisk (*) on the programming pages).
