Introducing the 6620 Computer
The 6620 Computer is a ruggedized, ergonomic, battery-
powered, touch-based computer, with input from finger
touch, stylus, keyboard, or scanner. It has integrated com-
munications and various combinations of external and in-
ternal peripherals. It is designed for a mobile environment.
AC Power

computer.
Batteries
The 6620 Computer contains a rechargeable lithium ion
(Li ION) main battery pack and a smaller rechargeable
Li ION backup battery.

NOTE: A discharged main battery pack takes up to 4.5 hours to recharge. A
backup battery that no longer accepts a charge must be replaced by
a factory-approved service provider.
BIOS
The 6620 Computer is shipped with a BIOS firmware
(PhoenixBIOS V4.0) and Windows 95. See the 6620 Com-
puter User’s Guide for instructions on how to change or up-
grade the computer.
