Safety
General Information
Safety Information
The MTP850 Ex/MTP810 Ex is restricted to occupational use
only to satisfy ICNIRP RF energy exposure requirements.
Before using the products, read the RF energy awareness
information and operating instructions in the Product Safety
and RF Exposure booklet (Motorola Publication part number
Safety Leaflet 6866588D20/6866588D45/6864117B25) to
ensure compliance with RF energy exposure limits.
Keep this User Guide and the Product Safety and RF
Exposure booklet in a safe place and make it available to
other operators in case the accessories are passed on to
other people.
Disposal Information
The European Union Waste of Electrical and
Electronic Equipment directive requires that
products sold into EU countries must have the
crossed out trashbin label on the product (or the package in
some cases). As defined by the WEEE directive, this cross-
out trashbin label means that customers and end-users in EU
countries should not dispose of electronic and electrical
equipment or accessories in household waste.
Customers or end-users in EU countries should contact their
local equipment supplier representative or service centre for
information about the waste collection system in their
country.
Before using these products, read the
operating instructions for safe usage
contained in the Product Safety and RF
Exposure booklet 6866588D20/6866588D45/
6864117B25.

Copyright Information
The Motorola products described in this manual may include
copyrighted Motorola computer programs stored in
semiconductor memories or other media. Laws in the United
States and other countries preserve for Motorola certain
exclusive rights for copyrighted computer programs
including, but not limited to, the exclusive right to copy or

Accordingly, any copyrighted Motorola computer programs
contained in the Motorola products described in this manual
may not be copied, reproduced, modified, reverse-
engineered, or distributed in any manner without the express
written permission of Motorola. Furthermore, the purchase of
Motorola products shall not be deemed to grant either directly
or by implication, estoppel, or otherwise, any license under
the copyrights, patents or patent applications of Motorola,
except for the normal non-exclusive license to use that arises
by operation of law in the sale of a product.
Product Specific Information
• Max. Voltage 7.9 V
• Max. Current 1.2 A
• Max. RF Power 1 Watt
• Max. Speaker Load 1 Watt at 20 Ohms
• Antenna Impedance 75 Ohms
• Operation Temperature Range -10 °C to +50 °C
• Operating Time Continuous / Intermittent
In general, the radio transmit and receive time (operating cycle
time) is determined by the communication system. On overload,
respectively on extensive use beyond the systems specifications
at high ambient temperatures, the radio is protected by its
thermal control, which cuts down the RF output power, thus
reducing the radio coverage range.

Safety
Icon Conventions
The document set is designed to give the reader more visual
cues. The following graphic icons are used throughout the
documentation set. These icons and their associated
meanings are described below.
The signal word Warning with the associated
safety icon implies information that,
if disregarded, could result in death or serious
injury, or serious product damage.
The signal word Caution with the associated
safety icon implies information that, if
disregarded, may result in minor or moderate
injury, or serious product damage.
The signal word Caution may be used without the
safety icon to state potential damage or injury that is
not related to the product.
Notes contain information more important than the surrounding
text, such as exceptions or preconditions. They also refer the
reader elsewhere for additional information, remind the reader
how to complete an action (when it’s not part of the current
procedure, for instance), or tell the reader where something is
located on the screen. There is no warning level associated with
a Note.

Battery Maintenance
The performance of the rechargeable battery delivered with
your terminal depends on the way the battery is treated.
Therefore, to comply with the Motorola warranty for batteries
and to assure high performance and a long life cycle of your
Motorola rechargeable battery, please read and follow the
maintenance rules stated below.
• As part of an Annual Battery Maintenance Program or as
required (when the battery contacts are dirty or show signs
of wear) it is recommended that the Battery‘s Radio-side
and Charger-side contacts are cleaned with
DeoxIT®GOLD cleaner/lubricant. DeoxIT®GOLD
(Supplier CAIG Labs, P/N G100P) cleaner/lubricant pen
has been found to be very effective at cleaning and
extending the life of the battery‘s contacts. DeoxIT®GOLD
cleaner/lubricant is available at numerous electronics
suppliers (Radio Shack, McMaster Carr, Fry’s, etc.) and
directly from manufacturer, CAIG Labs, at
http://www.caig.com. This pen based package is
recommended as it provides better access to the recessed
contacts of the battery. The pen’s tip may need to be
modified (trimmed on the sides) to improve penetration
into the battery contact slots. Per the manufacturer’s
instructions, shake the pen until the fluid begins to flow
and wipe the battery's contact surface with the felt tip.

Getting Started
After cleaning, inspect the contact surfaces for signs of
advanced wear. Advanced contact wear is defined as wear
through either the contact platings (gold and nickel) to the
base metal (copper). Copper exposure is characterized by
a distinctive orange-brown metal appearance surrounded
by the silvery nickel underplate and gold top coat. In some
cases, a magnified (10x minimum) inspection may be
required to verify wear through to the base material.
Polishing of the gold or nickel surface is common and is
not considered a need for replacement. In instances where
advanced wear is evident, the battery should be replaced.
• After cleaning the contact areas of any foreign material, let
the lubricant/cleaner dry for 2 minutes. Replace the battery
on the radio and test for intermittency by moving the
battery relative to the radio as might occur in regular use.
Regular maintenance (at least annually) of this area is
recommended to ensure contamination free interface and
to prolong the life of the battery contacts.
Storage
Do not store your battery where the temperatures will exceed
+60 °C or fall below -20 °C.
New Lithium-Ion batteries (i.e.batteries that have never been
charged before) may be stored for up to 2 years (with up to
50% of maximum charge) in well ventilated, cool and dry
areas with some capacity loss in life cycle.
Batteries, which have already been charged and then stored
for more than 2 months should be recharged overnight (14-
16 hours) before use.
Extending Battery Life
A battery is an expendable part and may need replacing
during the life of the terminal.To ensure maximum service life
of your handset, always replace the battery with a genuine
Motorola replacement.

10
In order to ensure maximum life from your battery, do not
place the handset and/or battery in the charger, unless you
really want to charge the battery.
Battery Charging Temperature
Your charger will only charge your battery when it is at
temperature range of 1°C to 37 °C.
This is due to the fact that the internal battery cell can be
charged in the temperature range of 0 °C to 45 °C.
As the temperature gets colder (close to 0 °C) less capacity
is stored in the battery.
If, during charging, the temperature is out of range, the
battery might not be fully charged since the charging is
temporarily stopped until the temperature becomes suitable.
The range of battery operation is from 0 °C to +45 °C in
charger mode and from -10 °C to +50 °C in discharge
(application) mode.
First Time Battery Charging
Always charge your new battery/(whichever type) overnight
(14 - 16 hours) before using it. This is referred to as
Initialising and will ensure maximum battery start capacity.
Battery Charging Rules
Generally, to reduce the number of charge cycles as much as
you can wait for Low Battery message to charge as this will
ensure maximum battery life.
Do not use your charger as a terminal stand or leave your
terminal and fully charged battery connected to the charger
whilst not charging. Continuous charging will shorten the
battery life.
Additional Battery Warnings/Cautions
• Battery Storage above 60° C (140° F)
and below -20° C (-4° F) is NOT recommended.
• To prevent injury, do not allow metal objects to contact the
battery terminals.

11
Getting Started
• Do NOT disassemble.
• Do NOT throw in fire.
• Do NOT dispose of battery in household waste.
