Using Power Options
Use the following options to power the printer:
•AC — AC/DC Power Supply
•DC — Cigarette Adapter
•Batteries — NiMH
The red-tagged cable attached to the printer connects
to the AC adapter cable. The white-tagged cable
connects to the cigarette lighter adapter for use in
vehicles. If neither the red nor the white cable is in use,
the printer is running off the battery.
The third cable (RJ11 telephone style) is the data cable
(see Attaching Cables on page 12). The fourth cable,
blue-tagged, is a third cradle connection used to
connect to external cradle, either in a truck or a bag
solution.
