CHARGING & COMMUNICATIONS
The main and backup batteries may not be charged to full for shipment. When you first
receive the package, you will need to charge the main battery to full before using the
mobile computer. Instead of direct charging, you may use a cradle or charger to charge
the Mobile Computer or spare batteries.
Because the internal backup battery is constantly charged from the main battery, the
initial charging requires inserting the battery pack to the mobile computer and then
connecting the mobile computer for direct charging or via cradle. This will have both the
main and backup batteries charged at the same time.
Charging Time
 Main battery: It takes approximately 4 hours to charge the main battery to full (from the
adaptor). The LED above the screen is red while charging and will turn green when charging is
done.
 Backup battery: It takes at least 8 hours to charge the backup battery to full. The main
battery must be inserted and left inside, whether the mobile computer is in use or not.
However, it is not necessary to fully charge the backup battery for the mobile computer to
work.
Charging Temperature
 It is recommended to charge the battery at room temperature (18°C to 25°C) for optimal
performance.
 Battery charging stops when the temperature drops below 0°C or exceeds 40°C.
Operation on Battery Power
 When 802.11b/g and BT are all enabled on battery power, the main battery charge will drop
down substantially.
 In order to prevent a cold boot after the battery is drained out, we suggest that you keep a
fresh battery for replacement or connect the mobile computer to an external power.
USING WIRELESS NETWORKS
The mobile computer supports state-of-the-art wireless technologies, Bluetooth and
802.11b/g, so that it is able to send/receive data in real time in an efficient way.
