Turn the transceiver power off in the following locations:
• In explosive atmospheres (inammable gas, dust particles, metallic
powders, grain powders, etc.).
• While taking on fuel or while parked at gasoline service stations.
• Near explosives or blasting sites.
• In aircraft. (Any use of the transceiver must follow the instructions
and regulations provided by the airline crew.)
• Where restrictions or warnings are posted regarding the use of
radio devices, including but not limited to medical facilities.
• Near persons using pacemakers.
• Do not disassemble or modify the transceiver for any reason.
• Do not place the transceiver on or near airbag equipment while the
vehicle is running. When the airbag inates, the transceiver may
be ejected and strike the driver or passengers.
• Do not transmit while touching the antenna terminal or if
any metallic parts are exposed from the antenna covering.
Transmitting at such a time may result in a high-frequency burn.
• If an abnormal odor or smoke is detected coming from the
transceiver, switch the transceiver power off immediately,
remove the battery pack from the transceiver, and contact your
KENWOOD dealer.
• Use of the transceiver while you are driving may be against trafc
laws. Please check and observe the vehicle regulations in your
area.
• Do not expose the transceiver to extremely hot or cold conditions.
• Do not carry the battery pack (or battery case) with metal objects,
as they may short the battery terminals.
• When operating the transceiver in areas where the air is dry, it is
easy to build up an electric charge (static electricity). When using
an earphone accessory in such conditions, it is possible for the
transceiver to send an electric shock through the earphone and to
your ear. We recommend you use only a speaker/microphone in
these conditions, to avoid electric shocks.

Information concerning the battery pack:
The battery pack includes ammable objects such as organic
solvent. Mishandling may cause the battery to rupture
producing ames or extreme heat, deteriorate, or cause other
forms of damage to the battery. Please observe the following
prohibitive matters.
• Do not disassemble or reconstruct battery!
The battery pack has a safety function and protection circuit to
avoid danger. If they suffer serious damage, the battery may
generate heat or smoke, rupture, or burst into ame.
• Do not short-circuit the battery!
Do not join the + and – terminals using any form of metal (such
as a paper clip or wire). Do not carry or store the battery pack in
containers holding metal objects (such as wires, chain-necklaces or
hairpins). If the battery pack is short-circuited, excessive current will
ow and the battery may generate heat or smoke, rupture, or burst
into ame. It will also cause metal objects to heat up.
• Do not incinerate or apply heat to the battery!
If the insulator is melted, the gas release vent or safety function is
damaged, or the electrolyte is ignited, the battery may generate
heat or smoke, rupture, or burst into ame.
• Do not leave the battery near re, stoves, or other heat
generators (areas reaching over 80°C/ 176°F)!
If the polymer separator is melted due to high temperature, an
internal short-circuit may occur in the individual cells and the
battery may generate heat or smoke, rupture, or burst into ame.
• Do not immerse the battery in water or get it wet by other
means!
If the battery’s protection circuit is damaged, the battery may
charge at extreme current (or voltage) and an abnormal chemical
reaction may occur. The battery may generate heat or smoke,
rupture, or burst into ame.
• Do not charge the battery near re or under direct sunlight!
If the battery’s protection circuit is damaged, the battery may
charge at extreme current (or voltage) and an abnormal chemical
reaction may occur. The battery may generate heat or smoke,
rupture, or burst into ame.
B62-2580-00_0i-vi.indd 4 7/5/13 1:56 PM
v
• Use only the specied charger and observe charging
requirements!
If the battery is charged in unspecied conditions (under high
temperature over the regulated value, excessive high voltage or
current over regulated value, or with a remodeled charger), it may
overcharge or an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into ame.
• Do not pierce the battery with any object, strike it with an
instrument, or step on it!
This may break or deform the battery, causing a short-circuit. The
battery may generate heat or smoke, rupture, or burst into ame.
• Do not jar or throw the battery!
An impact may cause the battery to leak, generate heat or smoke,
rupture, and/or burst into ame. If the battery’s protection circuit
is damaged, the battery may charge at an abnormal current (or
voltage), and an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into ame.
• Do not use the battery pack if it is damaged in any way!
The battery may generate heat or smoke, rupture, or burst into
ame.
• Do not solder directly onto the battery!
If the insulator is melted or the gas release vent or safety function
is damaged, the battery may generate heat or smoke, rupture, or
burst into ame.
• Do not reverse the battery polarity (and terminals)!
When charging a reversed battery, an abnormal chemical reaction
may occur. In some cases, an unexpected large amount of current
may ow upon discharging. The battery may generate heat or
smoke, rupture, or burst into ame.
• Do not reverse-charge or reverse-connect the battery!
The battery pack has positive and negative poles. If the battery
pack does not smoothly connect with a charger or operating
equipment, do not force it; check the polarity of the battery. If the
battery pack is reverse-connected to the charger, it will be reverse-
charged and an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into ame.
B62-2580-00_0i-vi.indd 5 7/5/13 1:56 PM

• Do not touch a ruptured and leaking battery!
If the electrolyte liquid from the battery gets into your eyes, wash
your eyes with fresh water as soon as possible, without rubbing
your eyes. Go to the hospital immediately. If left untreated, it may
cause eye-problems.
• Do not charge the battery for longer than the specied time!
If the battery pack has not nished charging even after the
regulated time has passed, stop it. The battery may generate heat
or smoke, rupture, or burst into ame.
• Do not place the battery pack into a microwave or high
pressure container!
The battery may generate heat or smoke, rupture, or burst into
ame.
• Keep ruptured and leaking battery packs away from re!
If the battery pack is leaking (or the battery emits a bad odor),
immediately remove it from ammable areas. Electrolyte leaking
from battery can easily catch on re and may cause the battery to
generate smoke or burst into ame.
• Do not use an abnormal battery!
If the battery pack emits a bad odor, appears to have different
coloring, is deformed, or seems abnormal for any other reason,
remove it from the charger or operating equipment and do not use
it. The battery may generate heat or smoke, rupture, or burst into
ame.

is switched ON and the VOX Gain level is congured to a higher,
more sensitive level, louder received signals may cause the
transceiver to start transmitting.
◆ If no operation is performed for 20 seconds, the transceiver will exit
VOX setup mode.

NXDN
NXDN is a general term for the NXDN wireless communication
protocol which uses 4 Level FSK. Various data communications,
including individual and group voice communications, Status
calls, and GPS data transmission, are possible.
INDIVIDUAL/GROUP CALLS
Each channel is set up with an individual or group ID list number.
To make a call, select the channel with the ID list number you
wish to call, then press the PTT switch to start the call.
• Your dealer may also have set Selcall on PTT for Individual or
Group calls, allowing you to make an Individual or Group call when
pressing the PTT switch.
• To page the target transceiver instead of initiating a voice call,
press the key programmed as [Paging Call].
• If PTT Proceed tone is enabled, the Proceed tone will sound. After
the tone ends, you can being the call.
■ Receiving
When you receive an individual call, a ringing tone will
sound. Respond to the call by pressing the PTT switch.
• If the auto reset timer expires before you respond to the call,
the call will end. Your dealer can set the duration for the auto
reset timer (default is 10 seconds).
When you receive a group call and the received group ID
matches the ID set up on your transceiver, a ringing tone
will sound and you can hear the caller’s voice.
STATUS CALL
You can transmit your status (preset by your dealer) to the
target transceiver by pressing the key programmed as [Call 1]
or [Call 2], if they have been set up with an NXDN Status.
• Channels are set up with ID list numbers by your dealer. Select the
desired channel before sending the status call.

BACKGROUND OPERATIONS
TIME-OUT TIMER (TOT)
The Time-out Timer prevents callers from using a channel
for an extended duration. If you continuously transmit for the
duration programmed by your dealer (default is 1 minute),
transmission will stop and a warning tone will sound. To stop
the tone, release the PTT switch.
BATTERY SAVER
When activated by your dealer, the Battery Saver function
decreases the amount of power used after no signal is present
and no operations are being performed for 5 seconds. When a
signal is received or an operation is performed, Battery Saver
turns off.
Note: While the Battery Saver is operating, the LED may ash
green when receiving a QT/DQT signal which does not match the
QT/DQT tone/code set up in your transceiver.
LOW BATTERY WARNING
While operating the transceiver, the Low Battery Warning
sounds until the PTT switch is released and the LED indicator
blinks red when the battery needs recharged or replaced.
BUSY CHANNEL LOCKOUT (BCL)
When activated, BCL prevents you from interfering on a
channel that is already in use. Pressing the PTT switch will
cause an alert tone to sound and the transceiver will not
transmit. Release the PTT switch to stop the tone.
Note: Ask your dealer for an explanation on how BCL functions
when using QT, DQT, RAN, or Optional signaling.

If BCL Override has been programmed, you can transmit over
the current signal:
1 Press and hold the PTT switch.
• If the channel is already in use, a warning tone will sound.
2 Quickly release and then press the PTT switch again.
3 Speak into the transceiver as you would during a normal call.
PTT ID
PTT ID is the transceiver unique ID code which is sent each
time the PTT switch is pressed and/or released.
Note: PTT ID can be made only in analog operation.
SIGNALING
■ QT/ DQT
The Encoder/Decoder function uses QT/ DQT to segregate
talk groups, so users only hear calls from their own group.
■ Radio Access Number (RAN)
RAN is a signaling system designed for digital radio
communications. When a channel is set up with a RAN,
squelch will only open when a call containing a matching
RAN is received. If a call containing a different RAN is
made on the channel you are using, you will not hear the
call. This allows you to ignore (not hear) calls from other
parties who are using the same channel.
■ NXDN ID
NXDN ID is an optional signaling system available only for
digital communications.
■ DTMF
A DTMF PTT ID is included for dispatch operations or
simple remote control applications. The DTMF decode
capabilities include Selective Call ID, Transpond with ID,
and “Wild Card” Group Calling.

■ 2-Tone
2-tone Signaling opens the squelch only when your
transceiver receives a call containing matching 2 tones.
■ FleetSync
Utilizing JVC KENWOOD’s FleetSync digital signaling
protocol, this transceiver has PTT ID and Selective
Calling capabilities for managed dispatch operations. For
hazardous/hostile duty environments, the Side1 or Side 2
key can be programmed for Emergency status to alert the
dispatcher and/or operator in distress.
■ MDC-1200
The following features are available with the built-in MDC
signaling: PTT ID Encode, Emergency Encode, Stun/
Revive Decode, and Radio Check Decode.
Note: The transceiver cannot decode MDC-1200 if the
FleetSync baud rate is 2400 bps.
COMPANDER
If programmed by your dealer for a channel, the compander
will remove excessive noise from transmitted signals, to
provide higher clarity of signals.
Note: The compander is used only in analog operation.
VOICE ANNUNCIATION
If enabled by your dealer, when changing the zone and
channel, an audio voice will announce the new zone and
channel number.

RADIO FREQUENCY ENERGY SAFETY INFORMATION
This KENWOOD transceiver has been tested and complies with the standards listed below, in regards
to Radio Frequency (RF) energy and electromagnetic energy (EME) generated by the transceiver.
• FCC RF exposure limits for
Occupational Use Only
. RF Exposure limits adopted by the FCC are generally
based on recommendations from the National Council on Radiation Protection and Measurements, & the
American National Standards Institute.
• FCC OET Bulletin 65 Edition 97-01 Supplement C
• American National Standards Institute (C95.1 – 1992)
• American National Standards Institute (C95.3 – 1992)
This KENWOOD transceiver generates RF EME while transmitting. RF EME (Radio Frequency Electric &
Magnetic Energy) has the potential to cause slight thermal, or heating effects to any part of your body less
than the recommended distance from this radio transmitter’s antenna. RF energy exposure is determined
primarily by the distance to and the power of the transmitting device. In general, RF exposure is minimized
when the lowest possible power is used or transmission time is kept to the minimum required for consistent
communications, and the greatest distance possible from the antenna to the body is maintained. The
transceiver has been designed for and is classified for
Occupational Use Only
. Occupational/ controlled
exposure limits are applicable to situations in which persons are exposed to RF energy as a consequence
of their employment, and such persons have been made aware of the potential for exposure and can
exercise control over their exposure. This means you can use the transceiver only if you are aware of
the potential hazards of operating a transceiver and are familiar in ways to minimize these hazards. This
transceiver is not intended for use by the general public in uncontrolled environments. Uncontrolled
environment exposure limits are applicable to situations in which the general public may be exposed to RF
energy, or in which the persons who are exposed as a consequence of their employment may not be fully
aware of the potential for exposure or cannot exercise control over their exposure.
The following list provides you with the information required to ensure that you are aware of RF
exposure and of how to operate this transceiver so that the FCC RF exposure limitations are not
exceeded.
• While transmitting (holding the PTT switch or speaking with VOX enabled), always keep the antenna
and the radio at least 3 cm (1 3/16 inches) from your body or face, as well as from any bystanders. A
LED on the top of the radio shows red when the transmitter is operating in both PTT and VOX modes.
• Do not transmit for more than 50% of the total transceiver use time; transmitting over 50% of the total use
time may exceed the limits in accordance to the FCC RF exposure requirements. Nominal transceiver
operation is 5% transmission time, 5% reception time, and 90% stand-by time.
• Use only the specified antenna for this transceiver; this may be either the antenna provided with the
transceiver or another antenna authorized by KENWOOD.
Use only KENWOOD authorized accessories (antennas, battery packs, belt clips, Speaker/ Mics
or headsets etc.): When worn on the body, always place the radio in a KENWOOD recommended
clip or carrying case meant for this product. The use of other than recommended or approved
body- worn accessories may result in RF exposure levels which exceed the FCC’s occupational/
controlled environment RF exposure limits.
To ensure that your exposure to RF EME is within the FCC limits for occupational use, you must
observe and adhere to the above points.
Electromagnetic Interference Compatibility
Electronic devices are susceptible to electromagnetic interference (EMI) if they are not adequately
shielded or designed for electromagnetic compatibility. Because this transceiver generates RF
energy, it can cause interference to such equipment.
• Turn OFF your transceiver where signs are posted to do so. Hospitals and health care facilities use
equipment that is sensitive to electromagnetic radiation.
• Turn OFF your transceiver while on board an aircraft when so instructed. Use of the transceiver must
be in accordance with airline regulations and/or crew instructions. B59-2687-00
