Overview

The MX3-CE is a rugged, portable, hand-held Windows CE computer capable of wireless data
communications. The MX3-CE can transmit information using a 2.4 GHz radio (with an internally
mounted antenna) and it can store information for later transmission through an RS-232 or
InfraRed port.
The MX3-CE is horizontally oriented and features backlighting for the display. The touch-screen
display supports graphic features and Windows icons that the Windows CE operating system
supports. The keys on the keypad are constructed of a phosphorescent material that can easily be
seen in dimly lighted areas. The MX3-CE is a Windows CE compatible computer that can be
scaled from a limited function batch computer to an integrated RF scanning computer. A stylus is
enclosed with the MX3-CE to assist in entering data and configuring the unit.

About Lithium-Ion Batteries

Li-Ion batteries (like all batteries) gradually lose their capacity over time (in a linear fashion) and
never just stop working. This is important to remember -- the MX3-CE is always 'on' even when
in the Suspend state and draws battery power at all times. Use the Start | Settings | Control Panel |
Power Properties | Charge tab to check the battery status and power reading. The following chart
is an approximation. Actual battery capacity may vary based on usage, ambient temperature and
peripherals drawing power from the MX3-CE:
Deciding when to put a fully charged Main Battery pack in the MX3-CE is difficult to quantify
because it is very application specific. 1000 mAh may be the cutoff for one customer who uses the
computer frequently, while 300 mAh may be perfectly fine for a customer who occasionally uses
the computer. You need to determine the point at which battery life becomes unacceptable for
your business practices and replace the Main Battery pack before that point.

Introduction

Until the Main Battery and Backup Battery are completely depleted, the MX3-CE is
always drawing power from the batteries (On).
100% capacity 1400 mAh minimum
80% capacity 1120 mAh minimum
Always store unused mobile devices with a fully charged main battery pack installed.
LXE recommends the mobile device be connected to an external power source
periodically to retain optimum power levels in the main battery pack and the backup
battery.
