BATTERY INFORMATION
Battery Care and Tips
This product is powered by a nickel-metalhydride (NiMH) or lithium-ion rechargeable
battery.
The following battery tips will help you obtain the
highest performance and longest cycle life from
your Motorola rechargeable battery.
• Charge your new battery overnight (14-16 hrs)
before using it to obtain maximum battery
capacity and performance.
• Charging in non-Motorola equipment may lead
to battery damage and void the battery warranty.
• When charging a battery that is attached to the
radio, turn the radio off to ensure a full charge.
• The battery should be at about 25°C (room
temperature) whenever possible. Charging a
cold battery (below 10°C) may result in leakage
of electrolyte and ultimately, in failure of the
battery.
• Charging a hot battery (above 35°C) results in
reduced discharge capacity, affecting the
performance of the radio. Motorola rapid-rate
battery chargers contain a temperature-sensing
circuit to ensure that the battery is charged
within these temperature limits.
• New batteries can be stored up to two years
without significant cycle loss. Store new/unused
batteries in a cool dry area.
• Batteries which have been in storage should be
charged overnight.
• Do not return fully charged batteries to the
charger for an “extra boost”. This action will
significantly reduce cycle life.
• Do not leave your radio and battery in the
charger when not charging. Continuous charging
will shorten battery life. (Do not use your charger
as a radio stand.)
• For optimum battery life and operation use only
Motorola brand chargers. They were designed to
operate as an integrated energy system.

Recycling or Disposal of Batteries
Motorola endorses and encourages the recycling
of all re-chargeable batteries. Contact your local
Motorola dealer for further information.
Charging the Battery
If a battery is new, or its charge level is very low,
indicated by high pitched warning tones, you will
GETTING STARTED
need to charge the battery before you can use it
in your radio.
Note: Batteries are shipped uncharged from the
factory. New batteries could prematurely
indicate full charge, charge a new battery for
14-16 hrs before initial use.
Charger LED Status

PERSONALITY
The personalities described below are
programmed into your radio by your dealer and
are accessible via the personality button.
A radio personality contains data such as
frequencies, alert tones, permitted calls etc.
which determines the operation of your radio.
Your radio may be programmed with up to 2
different personalities, selected from MPT,
Talkgroup Select and Conventional.
MPT
This personality permits the radio to operate in
a trunked mode. Incoming and outgoing calls
are set up using a defined set of rules or
protocol between your radio and a controller in
a similar manner to your home telephone. Your
radio ‘registers’ onto an MPT trunked system
as described in GETTING STARTED - Radio
Registration.
PERSONALITY
19
English
Talkgroup
Talkgroup is an MPT personality following the
same rules or protocol, but is primarily for
talkgroup calls. In talkgroup personality,
talkgroups are contained in a Talkgroup list,
similar to the Contact list, which is scrolled and
selected using the Rotary Knob (1).
PERSONALITY
On selection of a talkgroup, you may send and
receive calls as described below.
Fixed and Dynamic Groups
These groups form part of the Talkgroup
Personality, such that when this personality is
selected your talkgroup list shows only these
groups.
A fixed group is a group of users, the address
(number/alias) of which is preprogrammed into
your radio by your dealer.
A dynamic group is a group of users, the
address (number) of which is sent to your radio
‘over air’ at any time via the system controller.
Therefore at any time you may become a
member of a dynamic group, able to receive
calls and (depending on how your radio is
programmed) send calls to that group.
Incoming calls to fixed and dynamic group
numbers are detailed in Receiving a Call.
To make an outgoing call to a selected
talkgroup, press the PTT and speak after the
confidence tone.
Calls are cleared in the normal manner.
If the system is busy an engaged tone will be
heard, release the PTT and wait for the
confidence tone. You may then proceed with
the call by pressing the PTT.
English

Conventional Mode
In the conventional mode your radio operates
as a standard two-way radio.
Select the personality number which
corresponds to Conventional mode as
described in Personality Selection.
Use the rotary knob (1) to select the desired
channel.
Prior to transmission always make sure that
the channel is free (red LED not flashing).
Press the PTT (4) to transmit, release to listen.
The red LED lights while the radio transmits
and flashes if the channel is busy.
Some channels may be monitored for activity
by pressing the Clear button (3).
In the conventional mode, the radio is
