 Backup Battery
The backup battery on the main board takes charge when the main battery is
removed or drained out. When fully charged, the 3.0 V/7 mAh rechargeable Lithium
button cell helps retain data in SRAM and maintain the running of the real-time clock
and calendar for at least 30 days without the main battery. In the meantime, you
have to replace the main battery as soon as possible.
It takes at least twenty-four hours to fully charge the backup battery. However, it is
not necessary to fully charge the backup battery for the mobile computer to work.

1.1.1 INSERTING THE BATTERY
For shipping and storage purposes, save the mobile computer and the main battery in
separate packages. This will keep both batteries in good condition for future use.
Note: Any improper handling may reduce the battery life.
1) Hold the mobile computer face down in one hand as shown below.
2) Press the battery lid release and slide the battery lid.
3) Remove the battery lid by the other hand.
4) Slide the battery pack into the battery compartment at a proper angle (30°~45°) so
that the contacts of the battery are pressed onto the protruding contacts inside the
compartment. Make sure that the battery is snugly fit into the compartment.
5) Replace the battery lid and lock it firmly.
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.
