Chapter 1 Using the 9500PPC 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: To charge the batteries to full, it requires approximately 8 hours for the first time. After the
initial charging, it takes only 4 hours to charge the batteries to full.
Because the internal backup battery is constantly charged from the main battery, the initial charging
requires installing 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.
To charge the backup battery, make sure that you slide the DIP switch inside the battery
compartment to the ON position.
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 UNDERSTANDING THE BATTERY ICONS
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 (see below for battery status icon), 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 backup 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.
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.
