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

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.

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 (14­16 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.

8

Getting Started

If, during charging, the temperature is out of range, the

Turn clockwise
to attach

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.

Attaching the Antenna

Turn the MTP850 Off before installing or removing the antenna.

Insert the bottom of the antenna into the screw-in base on the
top of the MTP850. Turn clockwise until snug. Do not force.

MTP850 is idle.

The message will stay on your MTP850 display until a new
message is received.

29

If configured by your Service Provider, your MTP850 will
display an internal Home display until another message is
received.

Time & Date

If your Service Provider configured this feature, the MTP850
shows current time and date on home display.

You can also check time and date, wherever in menu, by
pressing relevant one-touch button.

Check in the menu options whether the Service Provider has
given you the capability of customising time and date settings

General

In Trunked Mode Operation (TMO) the MTP850 is used with
the infrastructure services within system coverage.

In Direct Mode Operation (DMO) the MTP850 is used without
infrastructure services required.

While operating in DMO the propagation travels directly from the
transmitting terminal antenna to the receiving terminal antenna,
with no assistance from any base station or tower. Therefore,
the range is critically dependent on the position of the user and
the antenna. To achieve best results, hold the terminal in the
hand as high as comfortably possible, and be sure not to
obstruct the antenna in any way. Be sure that the antenna is
clear from the body, cables, or other obstructions.
As there is no tower-mounted base station to assist, and the two
users are usually standing at ground level, the range is usually
shorter than that can be achieved towards a tower or hilltop. Any
obstructions (hills, buildings, etc.) between the users will further
decrease the range. Conversely, raising the terminal higher or
moving to a higher location may improve the range.

A MTP850 in DMO can communicate with the trunked
system (and vice-versa) through a gateway device. To use

Optns

Pre-emptive calling is particularly useful when you need to
speak urgently with a user whose terminal is busy in a non­emergency voice call.

A pre-emptive priority call (PPC) is either an Emergency
Group Call or a Private PPC (Simplex or Duplex call).

This feature allows to disconnect the on-going lower priority
call and to connect to the incoming higher priority call.

To place a PPC, see the Emergency Operation and Private
Call sections in the user guide.

Your MTP850 receives the call via speaker or earpiece,
according to the setting used when the PPC is received.

For call alert, see settings in the Vibrate menu option (page 126)
and the Tones menu option (page 132)

.

Receiving a PPC is explained in the following paragraphs.

In the screens, <Any> in Use refers to any of the non­emergency voice calls: Group, Private, Phone, or PABX.

Receiving an Emergency Group Call during a Call

The MTP850 receives the Emergency Group Call, drops the
on-going non-emergency voice call, and connects to the
Emergency Group Call.

Receiving a Private PPC during a Call

If configured by your Service Provider, the MTP850 receives
the PPC, drops the on-going, non-emergency, lower priority
voice call, and connects to the higher priority Private Call.

A PPC with lower or equal priority, will be dropped without
any indication to the called user and will enter the missed call

Broadcast Call

The Broadcast Group Call (also called Site
Wide Call) is a high-priority group call from the
console operator (or dispatcher) to all users
located at one or more sites. The terminals are
configured to monitor a Broadcast Call, but the

users cannot talk back.

The call can be received as normal Broadcast
Call or Emergency Broadcast Call.

The Broadcast Call pre-empts an on-going
Group Call that has the same (or lower) call
priority.

Packet Data

The Packet Data (PD) Service allows you to transfer data in a
TETRA system using the Internet Protocol (IP). Check with
your Service Provider for the availability of this feature.

For transferring data from a standard computer over the air
connect the computer via the Active Data Cable FKN4897 with
your MTP850. Your Service Provider has to setup additional
applications on your computer.

If set up by your Service Provider it is possible to accelerate
the transmission by using the Multi-Slot Packet Data (MSPD)
Service (refer to “Packet Data” on page 163).

Reseting the Terminal to Default Settings

This feature can be triggered only when you are in the idle
display of TMO, DMO, TXI, Repeater or Covert mode.

TMO Group Call

General

A Group Call is an instant communication between you and
others in a talkgroup that you select. Participants may join
(late entry) and leave an on-going Group Call. A talkgroup is
a pre-defined set of subscribers enabled to participate in and/
or invoke a Group Call, that is set up by your Service
Provider.

Talkgroups appear on your display as names or numbers (for
example: Sales, Service, Electricians, Talkgrp10).

Talkgroups can be divided into many folders. Each folder
may contain several talkgroups.

For ease of use, your MTP850 also provides the ability to:

• Perform an alphabetical search of the talkgroup aliases.
Scroll through the entire talkgroup list.

• Organise your groups into three folders (default name for
the first favorite folder is called My Groups which is set up
by your Service Provider).

Your talkgroups may be organized into scan lists (set up by
your Service Provider, or by yourself through the Menu).
When you activate one of these scan lists, your MTP850 will
continuously monitor the activities of the selected talkgroups.

By assigning priorities to the talkgroups defined in the scan
list, you will be capable of accepting calls that have higher
priority than the on-going call.

You can go to talkgroup, folder, or scanning selection when
the terminal is idle.

Pressing PTT during talkgroup selection switches to a new
group and starts a call.

Each talkgroup may have one associated Announcement
Talkgroup (ATG) that it monitors (if set up by your Service
Provider).

42

TMO Group Call

An ATG is a special group which is linked to a number of
talkgroups and has the highest priority level, thus enabling
broadcast of the call to all these talkgroups.

When an ATG is selected, the scanning icon is not displayed.
The MTP850 monitors the ATG scan list instead of the
selected scan list. The ATG scan list contains all the
talkgroups associated with a selected ATG. Your Service
Provider should advise what talkgroups are associated with
which Announcement Talkgroup.

Your MTP850 will always monitor the Group Calls in the ATG
scan list. To place an Announcement Call, you must first
select the specified Announcement Talkgroup as advised by
your Service Provider, otherwise you will only be able to
participate when an Announcement Talkgroup is received.

Activation and deactivation of talkgroup scanning has no
effect on the ATG scan list.

You can activate the Transmit Inhibit (TXI) Mode before
entering RF sensitive areas, e.g. in hospitals or in potentially
explosive areas, where safety can be jeopardized due to
MTP850 transmission radiation.

Radiation of the MTP850 is only suppressed if the TXI Mode is
activated or the MTP850 is separated from power supply.

In TXI Mode the MTP850 will not transmit under any
circumstances, except for the Emergency Call, which can be
initiated even if the MTP850 is in TXI Mode.

All MTP850 functions and keys which cause transmission,
e.g. registration to the network, change of talkgroup or folder,
sending messages, pressing PTT, etc. are disabled. In this
case the display shows “Not Allowed In TXI Mode” and the
MTP850 sounds the “Transmit Inhibit” tone.

When no danger to safety exists anymore (for instance if you
leave the RF sensitive area), the TXI Mode can be
deactivated and the MTP850 returns to standard operation.

Setting the TXI Mode is described in “Setting Transmit Inhibit
(TXI) Mode” on page 163.

Activated Transmit Inhibit is indicated by the solid orange

message by pressing the button/footswitch. In TMO mode,
the ability to send an Alarm and initiate a TMO Group/Private
call is unavailable.

Message addressing and sending:

• the address can be predefined by the Service Provider, if
not it is sent to currently selected group

• if no group is selected the message is sent to the reserved
address

• message is sent even if the user is involved in any active
call.

The indication depends on the setting from the Service
Provider. Visible/audible indications can be disabled for the
status message.

When the radio is PIN locked the user can still press the
Button/Footswitch to send the message.

If the radio is out of service the user will only see indication
that the operation failed.

DMO Group Call

General

In DMO, the MTP850 can be used without your Service
Provider’s infrastructure.

Direct Mode allows communication with other terminals also
operating in Direct Mode, which are on the same frequency
and talkgroup as your MTP850.

In DMO it is only possible to place Group Calls, Emergency
Group Calls and Private Simplex Calls.

You can receive a call:

• From the selected talkgroup

• From other users within talkback range (if configured by
your Service Provider). This is called an InterMNI (Mobile
Network identity) call.

• From an open group. (An open group is a super-group to
which all DMO groups belong.)

When you start a call, the members of the selected talkgroup
who have their units turned on, and are within the group
subscriber identity (as configured by the Service Provider),
will receive the transmission.

In DMO the MTP850 can communicate with the trunking
system (and vice-versa) if the Gateway option is enabled in
the MTP850.

To enhance the terminal’s DMO coverage area the DMO
group can link to a repeater if the Repeater option is enabled
in the terminal. Additionally the GW + Rep (gateway and
repeater) communication mode can be used.

If Transmit Inhibit is activated while the terminal is set to
DMO, the PTT is disabled. You can only listen. For detailed
information on Transmit Inhibit, see page 51. DMO Talkgroup
selection is allowed when Transmit Inhibit is activated.

Emergency call, and Hot Microphone was enabled by your
Service Provider, the Wait For Mic message will be
displayed. Your MTP850 will attempt to get a talk permit.

Silent Emergency Mode

Silent Emergency mode is a type of emergency services that
provides no audible indications and no keypad tones at the

Silent Emergency and TMO/DMO Mode

As the Silent Emergency is only available in TMO, radio will
change the mode from DMO to TMO. When the user is in a
private or group call, Silent Emergency waits until any of the
calls is ended to change the mode and enter the Silent
Emergency Mode.

If the Silent Emergency mode enters after the call the only
change on the display is the Private/Group notice which
disappears.

Power off in Silent Emergency mode

If user initiates the power off while in Silent Emergency mode

Overview

You can initiate an Emergency Group Call to a group.

You can receive an Emergency Group Call:

• From the selected talkgroup

• From other users within talkback range (if configured by
your Service Provider). This is called an InterMNI call.

• From an open group. (An open group is a super-group to
which all DMO groups belong.)

Emergency calls can be placed via gateway and repeater.
For gateway and repeater settings, see “Gateway/Repeater
Selection” on page 56.

Hot Microphone Feature in DMO
