6640 Computer
The 6640 Computer is a ruggedized, ergonomic, batteryĆ
powered, touchĆbased computer, with input from finger
touch, stylus, keyboard, or scanner.  It has integrated comĆ
munications and various combinations of external and inĆ
ternal peripherals.  It is designed for a mobile environment.
AC Power
Alternating Current (AC) power is available through an AC
power adapter.  This allows the computer to be operated
from standard electrical outlets.  The adapter cable charges
the main and backup batteries while simultaneously powerĆ
ing the computer.
Batteries
The 6640 Computer contains a rechargeable lithium ion 
(Li ION) main battery pack and a smaller rechargeable 
Li ION backup battery.
If the 6640 Computer is turned off at normal room temperaĆ
ture, a discharged battery takes about 4 hours to recharge.
If the 6640 Computer is turned on at normal room temperaĆ
ture, a discharged battery takes more than 6 hours to reĆ
charge due to the internal heat.
In extreme temperatures, charging may not happen.  The
battery temperature must be between 0_ and 55_ C for it to
charge.  Once outside this range, the battery will not
charge.

NOTE:
A backup battery that no longer accepts a charge must be replaced
by a factory-approved service provider.
