Using 8300 Mobile Computer
1.1.2 CHARGING THE BATTERY
The main and backup batteries may not be charged to full for shipment. When you first
receive the package, you will need to charge batteries to full before using the mobile
computer.
Note: For initial charging, it takes approximately 4 hours to fully charge the main
battery.
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
seating the mobile computer in the cradle for charging. This will have both the main and
backup batteries charged at the same time.
Note: For a new battery, make sure it is fully charged before use. Always prepare a
spare battery pack, especially when you are on the road.
1.1.3 CAUTION OF LOW BATTERY CHARGE
The battery pack is the only power source for the mobile computer to work. It also
charges the backup battery on the main board so that the data stored in SRAM can be
retained properly. Therefore, when the main battery charge goes low, you need to
replace the battery pack with a charged one or charge it as soon as possible. Most of all,
always save data before it is too late; you should upload important data on a regular
basis.
Warning: Data loss may occur with SRAM during low battery condition. Always save
data before running out of power or keep a fresh battery for replacement.
1.1.4 POWER MANAGEMENT
For any portable device, power management is a critical issue especially when you are on
the road. Below are some tips to help you save battery power.
Warning: Using backlight, wireless connectivity, and peripherals while on battery
power will substantially reduce battery power.
To speed up charging the mobile computer, turn off the mobile computer and seat it
in the cradle.
Bring a second battery pack on the road.
Stop wireless connectivity, Bluetooth or 802.11b/g when not in use.
