General Information
Safety Information
The MTP850 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
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 6864117B25.

Copyright Information
The Motorola products described in this manual may include
copyrighted Motorola computer programs stored in
semiconductor memories or other mediums. Laws in the
United States and other countries preserve for Motorola
certain exclusive rights for copyrighted computer programs,
but not limited to, including the exclusive right to copy or
reproduce in any form the copyrighted computer program.
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 licence under
the copyrights, patents, or patent applications of Motorola,
except for the normal non-exclusive licence to use that arises
by operation of the law in the sale of a product.
Product Specific Information
• Max. Voltage 4.2 V
• Max. Current 0.5 A
• Max. RF Power 1 or 1.8 Watt (Adjustable)
• Max. Speaker Load 0.5 Watts at 8 Ohms
• Antenna Impedance 50 Ohms
• Operation Temperature Range -25 °C to +60 °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.

General
Icon Conventions
The document set is designed to give the reader more visual
clues. 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.
Storage
Do not store your battery where the temperatures will exceed
+65 °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.
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.

9
Getting Started
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 +60 °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.
