1.1 BATTERY
Main Battery
The mobile computer is powered by a rechargeable 3.7 V/1800 mAh Li-ion battery
pack. When the mobile computer is turned on, it takes approximately four hous to
charge it to full from the power adapter (via cable or cradle) or less than 5 hours from
the USB cable (at 500 mA).
For power-saving purpose, always turn off the backlight while working in a well-lit
area. When the backlight is on for extended periods of time, the main battery will
become low sooner than expected.
The smart battery icon on the LCD screen shows the status of power consumption.
There are two ways to monitor a low battery charge or discharged battery from the
screen.
Examine the level of the 4-bar battery icon
Monitor voltage level (see section 3.5 Power)
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 twenty-five days without the main battery. In the meantime,
you have to replace the main battery as soon as possible.
It takes at least thirty hours to fully charge the backup battery. However, it is not
necessary to fully charge the backup battery for the mobile computer to work.

Note: Any improper handling may reduce the battery life.
1) Unhook the hand strap from the bottom of the mobile computer. Make sure to turn
off the mobile computer.
2) Hold the mobile computer still and press the release button to unlock the battery
cover.
3) Slide off the battery cover.
4) Use your finger to slide the locking plate towards its hinge to unlock the SD card
holder.
5) Flip up the SD card holder.
6) Insert your memory card (microSD or microSDHC) to the SD card holder.
7) Push the SD card holder down.
8) Slide the locking plate away from its hinge to secure the card.
9) Slide the battery pack into the battery compartment at a proper angle (30°~45°) so
that the tabs on the bottom of the battery are hooked in the grooves of the
compartment.
10) Push down the battery and make sure that the battery is snugly fit into the
compartment.
11) Slide the battery cover back onto the mobile computer until it clicks into place.

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. (see section
Note: For initial charging, it takes approximately 3~5 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.
1.7 Charging & Communications)
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 or use the charging/communication cable.
Bring a second battery pack on the road.
Stop wireless connectivity, Bluetooth or 802.11b/g that is not in use.

Chapter 1 Using 8400 Mobile Computer
1.2 MEMORY
The collected data can be sent back to a host computer immediately over wireless
networks, or stored in memory (SRAM) and upload later. The mobile computer is
equipped with a calendar chip for accurate time/date logging. When the main battery is
removed or drained, the backup battery on the main board is to retain the contents of
SRAM and maintain the running of real-time clock and calendar for at least 25 days, on
condition that the backup battery has already been fully charged.
If you want to put away the mobile computer for a couple of days, you should be aware
that data loss occurs when both the main and backup batteries discharge completely.
Therefore, it is necessary to upload data and files before putting away the mobile
computer!
1.2.1 READ-ONLY MEMORY (ROM)
4 megabytes flash memory for storing core, OS, application programs, fonts, etc.
1.2.2 RANDOM-ACCESS MEMORY (RAM)
Options include 4 or 16 megabytes SRAM for storing data. Its contents will be retained by
the backup battery.
1.2.3 SD CARD
Up to 4 GB high capacity memory card (microSDHC) is supported. Refer to section 1.1.1
Inserting the Battery & Memory Card
It can be used as extended data memory or as a USB disk when connecting to your
