Introduction 5
Installation and Operation
Introduction
The life and capacity of a Lithium Ion battery can vary significantly depending on the discharge
current and the environment in which it is used. As with all batteries, expect to see a reduction in
the total number of operations a fully charged battery pack can deliver as it ages.
Charging times may increase but will not exceed five hours. Battery packs do not need to be fully
discharged between charge cycles.
Normal Operations
The optimal operating temperature range for the MX8 Multi-Charger is between 50°F and 100°F
(10°C and 40°C). While charging, the multi-charger and battery pack will generate enough heat to
feel warm. This is normal and does not indicate a problem. Do not store the battery pack in direct
sunlight or anywhere the battery pack cannot cool down. If the battery pack is hot after removal
from the mobile device, allow it to cool at room temperature before placing it in the multi-charger.
Charge times may increase significantly if the battery is warm or hot, since it takes the battery
pack longer to cool down while in the charging bay. If the battery pack is hot from severe
environmental use and immediate recharging is necessary, place the battery pack in a cool air
stream or in a cool location until it is no longer warm to the touch before charging.
Do not use, place or store the MX8 Multi-Charger in hazardous locations.
Caring for Batteries
• Do not dispose of batteries into a fire. Burning will generate hazardous vapors and may
cause the battery to explode. Failure to observe this warning may result in injury from
inhalation of vapors or burns from flying debris.
• Do not immerse batteries in water or any other liquid. If batteries are immersed, contact
LXE.
• Do not disassemble or perform modifications to the battery. There are no user serviceable
components in the battery.
• Do not place battery into pocket or toolbox with conductive objects (coins, keys, tools,
etc.).
• A battery placed on damp ground or grass could be electrically shorted. Lay the battery
on its side when not in use.
• Do not store batteries above 140°F (60°C) for extended periods.
• Failure to observe these warnings could result in injury or damage to the battery from
rapid discharge of energy or overheating of the battery.

Setup / Installation
• Ensure that the location you choose for the battery multi-charger is well ventilated.
• Is not in high traffic areas.
• Has enough clearance to allow easy access to the power and ports on the back of the
device.
• Is protected from rain, dust or inclement weather.
1. Place the multi-charger on a horizontal, hard surface or fasten securely to a wall using the
keyhole openings on the bottom of the unit.
2. Plug the power cord into a properly grounded outlet. Locate or orient the AC cord so that it
will not be stepped on, tripped over or subjected to damage or stress.
3. On initial power-up, multi-charger LEDs light up for a few seconds.
Figure 4 AC Power Supply
The external Power Supply for the multi-charger is shipped with the multi-charger. If there is no
AC cable, please contact your LXE representative. The multi-charger power supply is intended for
use with the MX8 Multi-Charger only.

Orienting the Battery Pack
Caution!
When preparing the battery pack for insertion into the multi-charger well, hold the battery with its
four charging contacts in line with the charging contacts in the battery well. Aim the retaining
catch towards the back of the multi-charger.
It is important that battery packs are inserted into the charging well correctly.
Inserting the battery incorrectly could result in damage to the battery pack or the
multi-charger.
applied.
Fault Battery pack fault or failure.

Progress Monitoring 9
Inserting the Battery Pack
Push the locking tab towards the back of the battery well until it stays in place. Place the battery in
the battery well, making sure the tab at the top of the battery pack fits into the slot at the top end of
the battery well. With a hinging motion, slip the battery down into the battery well until the
locking tab clicks into place and the battery pack is secure in the battery well.
Failure to follow these instructions can result in damage to the main battery or the multi-charger.
Caution!
Do not "slam" or slide the battery pack into the battery well. Damage may result.
Progress Monitoring
The MX8 Multi-Charger indicates the status of a battery pack with an LED located below each
charging well.
Charge Timer
The charge timer is based upon the capacity of the battery pack. There are two ranges and two
different timeouts. The charging bay LED flashes red to indicate a fault when the multi-charger’s
timeout period has expired. The LED also indicates a fault if the battery voltage does not rise
above 2.5V after 60 minutes.

communicates the status of the charge operation.
Note: On initial power-up, all four charging LEDs will light red, yellow, green for 1 second
before turning off.

Maintenance 11
Maintenance
Use a clean soft cloth to wipe any dirt, moisture or grease from the battery pack, contacts or the
multi-charger. Do not use any liquid to clean the battery charging well or multi-charger contacts.
Unplug the multi-charger from power source before cleaning. Do not operate the multi-charger
with a damaged AC cord or plug.
Storage
Battery packs should be kept in a cool, dry place whenever possible. Do not store battery packs in
direct sunlight, on a metal surface, or anywhere the battery pack cannot cool down. Do not leave
the battery pack in a non-operating multi-charger. The battery pack may discharge through the
multi-charger rather than hold its charge.
Service
There are no user serviceable parts in the Rechargeable Lithium Ion Battery Pack or the MX8
Multi-Charger. Should your multi-charger require service, contact your LXE representative.
Do not operate the multi-charger if it has been dropped or damaged in any way. Return the multicharger to LXE.
Troubleshooting
The following is intended as an aid in determining whether the battery pack or the multi-charger may be
malfunctioning.
Problem Cause Solution
Battery pack does not fit in
battery well.
No battery pack in multicharger, but any of the LEDs are
on.
Charger is plugged into a live
outlet, battery pack is inserted,
but RED LED is OFF and no
other LEDs are on, or all LEDs
are off.
Different manufacturer's battery
pack, or there is an object in the
battery well.
Dirt or foreign objects are in the
battery well.
• Battery pack is not making
contact with charging
terminals in the battery
well.
• Faulty battery pack.
• New battery pack, same
result.
Check if the battery pack is LXE part
number 161376-0001. If not, do not use.
Remove the object from the battery well.
Unplug multi-charger from outlet.
Remove any dirt or foreign objects from
battery wells. If the LEDs continue to
remain ON, the multi-charger may be
defective. Return multi-charger to an
authorized LXE service center.
• Push battery pack in firmly. Do not
"slam" the battery pack into the
battery well.
• Replace battery pack.
• Contact LXE for replacement
options.

12 Troubleshooting
Problem Cause Solution
When you first put a fully
charged battery pack in the
battery well, the RED LED
comes on, indicating the battery
pack is charging.
LED is flashing RED at any
station.
During the first few minutes, the
multi-charger checks the battery
pack for correct voltage and
charge state. During this time
the LED is RED and is
continuously ON. After
charging is complete, the LED
is GREEN.
Current could not be sourced
through the battery pack due to
age, exhaustion or damage to
the cell(s). The battery pack
does not communicate with the
multi-charger.
OR
The battery pack voltage has not
reached 2.5V within 60 minutes
and the multi-charger has timed
out.
OR
The multi-charger’s timeout
period has expired.
There is nothing wrong with the battery
pack or multi-charger.
Contact LXE for battery pack
replacement options.
Contact LXE for battery pack
replacement options.
Make sure that the battery pack
temperature is within specification and
retry charging. If problem repeats,
contact LXE for battery pack replacement
options.
Solid YELLOW LED when
battery pack is inserted in the
multi-charger.
The battery pack is too hot or
too cold to charge.
Remove battery pack from the multicharger and allow it to adjust to room
temperature.
Note: If the battery pack is left in the
multi-charger, it will cool down or warm
to a temperature upon which the multicharger will begin the charge cycle.
However, depending on the temperature
of the battery, it may take 2-3 hours to
adjust. The cool-down of a battery pack
is much quicker if the battery is not in the
battery well.
