Tools needed:
• Phillips head screwdriver
Procedure Outline
The procedure consists of these basic steps:
• Mechanical installation of the Wireless module.
• Setting new parameters for the module. Certain modules are self-conguring,
but most will need you to enter some information into the printer’s memory. ou
must be certied to use Zebra’s proprietary software to perform this update.
If you send your printer back to the Factory Repair Services, your printer will be updated
as necessary to conform with the as-shipped configuration. Any changes you have made
to the printer may be removed.
Removing the Wireless Module
1. Turn the Printer off.
2. Remove the Battery Pack.
3. Remove and retain the screw from inside the battery compartment.
4. Remove the Wireless module, or if upgrading the printer from a cable ready
unit, remove the cover. Lift up the module from the bottom of the unit and pull
it out. Opening the latch to the printer’s media supply will make it easier to re-
move the module.
