FCC WARNING

This equipment generates or uses radio frequency energy.

Changes or modifications to this equipment may cause harmful

interference unless the modifications are expressly approved in the

instruction manual. The user could lose the authority to operate this

equipment if an unauthorized change or modification is made.

INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY

THE FCC

This equipment has been tested and found to comply with the limits

for a Class B digital device, pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against

harmful interference in a residential installation.

This equipment generates, uses and can generate radio

frequency energy and, if not installed and used in accordance

with the instructions, may cause harmful interference to radio

communications. However, there is no guarantee that the

interference will not occur in a particular installation. If this equipment

does cause harmful interference to radio or television reception,

which can be determined by turning the equipment off and on, the

user is encouraged to try to correct the interference by one or more of

the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment to an outlet on a circuit different from

that to which the receiver is connected.

• Consult the dealer for technical assistance.

PRECAUTIONS

• Do not charge the transceiver and battery pack when they are wet.

• Ensure that there are no metallic items located between the

transceiver and the battery pack.

• Do not use options not specified by KENWOOD.

• If the die-cast chassis or other transceiver part is damaged, do not

touch the damaged parts.

• If a headset or headphone is connected to the transceiver, reduce

the transceiver volume. Pay attention to the volume level when

turning the squelch off.

• Do not place the microphone cable around your neck while near

machinery that may catch the cable.

• Do not place the transceiver on unstable surfaces.

• Ensure that the end of the antenna does not touch your eyes.

• When the transceiver is used for transmission for many hours, the

radiator and chassis will become hot. Do not touch these locations

when replacing the battery pack.

• Always switch the transceiver power off before installing optional

accessories.

• The charger is the device that disconnects the unit from the AC

mains line. The AC plug should be readily accessible.

Turn the transceiver power off in the following locations:

• In explosive atmospheres (inflammable 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 aircrafts. (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 inflates, 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 traffic

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 with metal objects, as they may short

the battery terminals.

• Danger of explosion if the battery is incorrectly replaced; replace

only with the same type.

• 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 flammable objects such as organic solvent.

Mishandling may cause the battery to rupture producing flames 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 flame.

• 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-

necklace or hairpins). If the battery pack is short-circuited,

excessive current will flow and the battery may generate heat

or smoke, rupture, or burst into flame. 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 flame.

• Do not leave the battery near fires, 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

flame.

• Avoid immersing the battery in water or getting it wet by

other means!

If the battery becomes wet, wipe it off with a dry towel before

use. 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 flame.

vii

• Do not charge the battery near fires 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 flame.

• Use only the specified charger and observe charging

requirements!

If the battery is charged in unspecified conditions (under high

temperature over the regulated value, excessive high voltage

or current over regulated value, or with a remodelled charger),

it may overcharge or an abnormal chemical reaction may occur.

The battery may generate heat or smoke, rupture, or burst into

flame.

• 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

flame.

• Do not jar or throw the battery!

An impact may cause the battery to leak, generate heat

or smoke, rupture, and/or burst into flame. 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.

• Do not use the battery pack if it is damaged in any way!

The battery may generate heat or smoke, rupture, or burst into

flame.

• 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 flame.

• 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 flow upon discharging. The battery may

generate heat or smoke, rupture, or burst into flame.

viii

• Do not charge the battery for longer than the specified

time!

If the battery pack has not finished charging even after the

regulated time has passed, stop it. The battery may generate

heat or smoke, rupture, or burst into flame.

• Do not place the battery pack into a microwave or high

pressure container!

The battery may generate heat or smoke, rupture, or burst into

flame.

• Keep ruptured and leaking battery packs away from fire!

If the battery pack is leaking (or the battery emits a bad odor),

immediately remove it from flammable areas. Electrolyte

leaking from battery can easily catch on fire and may cause the

battery to generate smoke or burst into flame.

• 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 flame.

• 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

flame.

• Do not touch a ruptured and leaking battery!

If the electrolyte liquid from the battery gets into your eyes,

wash your eyes out with fresh water as soon as possible,

without rubbing your eyes. Go to the hospital immediately. If

left untreated, it may cause eye-problems.

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
