8400 Series Mobile Computer Reference Manual
INITIAL CHARGING
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. Refer to 1.7 Charging & Communications.
Note: For initial charging, it takes approximately 4~5 hours to fully charge the main
battery.
Warning: It is recommended that the charging devices be operated at room
temperature (18°C to 25°C) for optimal performance. The charging devices
will not charge the battery when the temperature exceeds 40°C.
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. It takes at least 72 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: In order to charge the backup battery to full, you must insert the main battery and
leave it for at least 72 hours, whether the mobile computer is in use or not.
SETTING LOCAL TIME
If you need to set your local time, go to System Menu |2. Settings |1. Clock. Refer
to 3.2.1 Clock.
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.
Go to System Menu |2. Settings |2. Backlight, and configure backlight period,
luminosity, as well as the shade effect. Refer to 3.2.2 Backlight.
Go to System Menu |2. Settings |4. Auto Off, and configure the amount of idle
time that must pass before the system will shut down automatically. Refer to 3.2.4
Auto Off.

1.1 BATTERY
1.1.1 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 approx. 4 hours to charge it to full from
the power adaptor (using RS-232 cable or cradle) or approx. 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)
Chapter 1
USING 8400 MOBILE COMPUTER

8400 Series Mobile Computer Reference Manual
1.1.2 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/18 mAh rechargeable Lithium button cell
helps retain data in SRAM and maintain the running of the real-time clock and calendar
for at least 25 days without the main battery. In the meantime, you have to replace the
main battery as soon as possible. It takes at least 72 hours to fully charge the backup
battery. However, it is not necessary to fully charge the backup battery for the mobile
computer to work.
Monitor voltage level (see section 3.5 Power)
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,
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.

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, font, 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
Secure Digital (SD) card is a flash memory data storage device. Up to 8 GB high capacity
memory card (microSDHC) is supported. Refer to Inserting Battery & Memory Card for
how to insert the microSD or microSDHC card. For more details, refer to 1.8 SD Card.
Note: (1) When SD card is present, the card icon will appear on the screen and flash
while being accessed.
(2) For an SD card that has never been used on 8400, a message like “Found New
