System Memory

System Memory
A CF Card FLASH is used for ROM, Flash for Windows operating system and Flash memory for bundled applications. The
Flash is configured as the primary boot device and contains the Windows operating system image, boot loader, OAL,
applications, utilities and device drivers.
Any flash remaining beyond the Windows operating system image is formatted for use as a persistent memory drive (which
appears in My Computer as the folder labeled System). Any programs or data stored in this folder will not be lost if the memory
backup battery fails.
The computer has one Type II CF+ slot. The computer supports and auto detects up to 256MB of Type I compact flash
memory.

Video Subsystem

The display has a 640 pixel (horizontal) by 240 pixel (vertical) format. Display contrast is 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. Touch screen allows mouse functions (pointing and tapping on
the display or Signature Capture) using an LXE approved stylus.
There are two types of displays available:
transflective greyscale monochrome. The transflective monochrome is optimized for outdoor use but may also be used
l
indoors. The monochrome display has an electroluminescent backlight.
transmissive color. The transmissive color display is optimized for indoor lighting. It cannot be used without the back-
l
light. The color display has 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 MX3X uses two batteries for operation.
A 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.

Audio Interface

An interface is available for headset operation. When a headset is plugged into the audio jack on the endcap, the main speaker
is disabled.
