E-EQ-MX3OGWW-D MX3 Installation and Operator’s Guide
The MX3 Hand Held Computer
Introduction
The MX3 is a rugged, portable, hand-held PC-compatible computer capable of wireless data
communications. The MX3 can transmit information using either a 900 MHz or 2.4 GHz radio
(with an internally mounted antenna). It can store information for later transmission through an
RS-232 or InfraRed port. The MX3 is horizontally oriented and features electroluminescent
backlighting for the display. The keys on the keypad are constructed of a phosphorescent material
that can easily be seen in dimly lighted areas.
The MX3 is an MS-DOS compatible computer designed to run as a batch unit or run software
applications such as LXE’s Terminal Emulator applications (ANSI Plus, LDS Plus, DOS 5250,
DOS 3270, TN3270 and TN5250).
Note: The “MX3 Reference Guide” contains MX3 technical information and advanced
functions.

Display
Figure 3 MX3 Display
The MX3 Display is a transflective monochrome LCD unit capable of supporting VGA graphics
modes. Display size is 640 x 240 pixels with an electroluminescent backlight. An optional touch
screen is available for batch and client server MX3s only.
Cleaning the Display
Keep fingers and rough or sharp objects away from the scan aperture and display. If the glass
becomes soiled or smudged, clean only with a standard household cleaner such as Windex®
without vinegar or use Isopropyl Alcohol. Do not use paper towels or harsh-chemical-based
cleaning fluids since they may result in damage to the glass surface. Use a clean, damp, lint-free
cloth. Do not scrub optical surfaces. If possible, clean only those areas which are soiled.
Lint/particulates can be removed with clean, filtered canned air.
Optional Touch Screen
A touch screen option is available that allows signature capture and touch input with the
appropriate software load. A pen stylus is included with the touch screen option. Contact LXE for
availability.

4 Display
MX3 Installation and Operator’s Guide E-EQ-MX3OGWW-D
Display Backlight
A display backlighting feature is available and depending upon programming, will operate in one
of three ways:
1. Backlighting Off. This is the most efficient way to operate the computer with
battery power.
2. Backlighting On For A Short Time. This will provide display backlighting for a
predetermined amount of time. Use of this feature will result in reduced battery life.
3. Backlighting On Whenever The Unit Is On. This provides full time
backlighting to the display whenever the unit is turned on. It greatly reduces the
expected battery life.
Display Backlight Timer
When the Display Backlight Timer expires the display backlight is turned off. The default value
for this parameter is 3 seconds. The value can be adjusted using the BIOS Setup. Refer to the
“MX3 Reference Guide”.
Any of the following will wake the display and display backlight:
• Display update by host or currently running application on the MX3
• Any key on the keypad
• Pen-touch on a touch screen display
When the display wakes up, the Display Backlight Timer will begin the countdown again. When
any of the above events occur prior to the timer expiring, the timer starts the countdown again.
The ability of touch screen activation to wake up the MX3 is configurable in BIOS Setup. Refer to
the “MX3 Reference Guide” for details.
