General Radio Operation
Receive / Transmit
Radio users who switch from analog to digital radios often assume
that the lack of static on a digital channel is an indication that the
radio is not working properly. This is not the case. Digital technology
quiets the transmission by removing the “noise” from the signal and
allowing only the clear voice or data information to be heard.
This section emphasizes the importance of knowing how to monitor a
channel for traffic before keying up to send a transmission.
Without Using Volume Set and Monitor Buttons
1 Turn the radio on and select
the desired zone and
channel.

Key Loading
Refer to the key-variable loader (KVL) manual for equipment
connections and setup.
1 Attach the KVL to your radio.
When it is attached, all radio
functions, except for power
down, backlight, and volume,
will be locked out.
2 Press the PTT button on the
KVL. This will load the
encryption keys into your
radio. When the key has
been loaded successfully,
the radio will sound a short
tone for single-key radios; for
multikey radios, an
alternating tone will be
heard.
Multikey
The multikey feature allows your radio to be equipped with as many
as 48 different encryption keys and supports the DES-OFB algorithm.
• Conventional Multikey — The encryption keys can be tied
(strapped), on a one-per-channel basis, through radio service
software. In addition, you can have operator-selectable keys,
operator-selectable keysets, and operator-selectable key erasure.
If talkgroups are enabled in conventional, then the encryption keys
are strapped to the talkgroups.
• Trunked Multikey — If you use your radio for both conventional
and trunked applications, you will have to strap your encryption
keys for trunking on a per-talkgroup or announcement-group
basis. In addition, you may strap a different key to other features
for example, dynamic regrouping, failsoft, or emergency talkgroup.
You can have operator-selectable key erasure.

Special Radio Features
Dynamic Regrouping (Trunking Only)
The dynamic regrouping feature lets the dispatcher temporarily
reassign selected radios to a single special channel so they can
communicate with each other. This feature is typically used during
special operations and is enabled by a qualified radio technician. You
will not notice whether your radio has this feature enabled until a
dynamic regrouping command is sent by the dispatcher.
Note: If you try to access a zone or channel that has been reserved
by the dispatcher as a dynamically regrouped mode for other
users, you will hear an invalid tone.
When your radio is dynamically regrouped, it automatically
switches to the dynamically regrouped channel. You see the
dynamically regrouped channel’s name, and hear a “gurgle”
tone.
Press the PTT button to talk; release it to listen.
When the dispatcher cancels dynamic regrouping, the radio
automatically returns to the zone and channel that you were
using before the radio was dynamically regrouped.

Trunking System Controls
Failsoft
The failsoft system ensures continuous radio communications during
a trunked system failure. If a trunking system fails completely, the
radio goes into failsoft operation and automatically switches to its
failsoft channel.
During failsoft operation:
Your radio transmits and receives
in conventional operation on a
predetermined frequency.
You hear a medium-pitched tone
every 10 seconds
When the trunking system returns to normal operation, your radio
automatically leaves failsoft operation and returns to trunked
operation.
• A medium-pitched tone
Out-of-Range
If you go out of the range of the system and can no longer lock onto a
control channel, you hear a low-pitched tone.
Your radio remains in this out-ofrange condition until it locks onto a
control channel, locks onto a
failsoft channel, or is turned off.

Helpful Tips
Battery
Battery Life
Battery life is determined by several factors. Among the more critical
are the regular overcharge of batteries and the average depth of
discharge with each cycle. Typically, the greater the overcharge and
the deeper the average discharge, the fewer cycles a battery will last.
For example, a battery which is overcharged and discharged 100%
several times a day, will last fewer cycles than a battery that receives
less of an overcharge and is discharged to 50% per day. Further, a
battery which receives minimal overcharging and averages only 25%
discharge, will last even longer.
Charging the Battery
Motorola batteries are designed specifically to be used with a
Motorola charger and vice-versa. Charging in non-Motorola
equipment may lead to battery damage and void the battery warranty.
Motorola-authorized battery chargers may not charge batteries other
than the ones listed on page 45.
The battery should be at about 77°F (25°C) (room temperature),
whenever possible. Charging a cold battery (below 50° F [10°C]) may
result in leakage of electrolyte and ultimately in failure of the battery.
Charging a hot battery (above 95°F [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 batteries are charged within the temperature limits stated
above.
Battery Charge Status
Your radio can indicate your battery’s charge status through LED and
sounds.
When your battery is low:
• you see the LED flash red when the PTT button is pressed
• you hear a low-battery “chirp” (short, high-pitched tone)

Battery Recycling and Disposal
Nickel-cadmium (NiCd) rechargeable batteries can be recycled.
However, recycling facilities may not be available in all areas. Under
various U.S. state laws and the laws of several other countries, NiCd
batteries must be recycled and cannot be disposed of in landfills or
incinerators. Contact your local waste management agency for
specific requirements and information in your area.
Motorola fully endorses and encourages the recycling of NiCd
batteries. In the U.S. and Canada, Motorola participates in the
nationwide Rechargeable Battery Recycling Corporation (RBRC)
program for NiCd battery collection and recycling. Many retailers and
dealers participate in this program.
