adjustable with key sequences. Backlighting is available and can be adjusted with key sequences.
The turn-off timing is configured through the Control Panel. The display controller supports
Windows CE graphics modes. Touchscreen allows mouse functions (pointing and taping on the

There are two types of displays available: transflective greyscale monochrome; and transmissive
color. The transmissive color display is optimized for indoor lighting. It cannot be used without
the backlight. The transflective monochrome is optimized for outdoor use but may also be used
indoors. The monochrome display has an electroluminescent backlight. The color displays have a
CCFL (Cold-Cathode Fluorescent Lighting) backlight.
The transflective display appears to have a greenish hue when the display is off or suspended. The
transmissive display appears black when the display is off or suspended.

Power Supply
The mobile device uses two batteries for operation.
• An 1900 mAh replaceable Lithium-Ion (Li-Ion) battery pack. The battery pack recharges
while the computer is in a powered cradle or when connected to the optional external
power sources. The main battery can be removed and inserted in the MX3 Multi-Charger
which simultaneously charges up to six battery packs in four hours.
• An internal 50 mAh Nickel Cadmium (NiCd) backup battery. The backup battery is
recharged directly by the main battery when it is in the mobile device. Full charging of the
backup battery may take several hours. The recharging of the backup battery is
automatically controlled by the operating system. The backup battery must be replaced by
qualified service personnel.
Optional AC adapters are available – external AC power supplies (US and International) and a
cigarette lighter adapter. See Chapter 3 “Power Supply”, “External Power Supply”.
When the backup battery and main battery are dead, the mobile device reverts to it’s default values
when a fully charged main battery is installed and the device is powered On again. Follow the
steps in section titled “Getting Started”.
