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.

• Use only KENWOOD specifi ed explosion-protected options for the
NX-203 and NX-303 transceivers.

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

• 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.

iii

Turn the transceiver power off in the following locations:

• 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 wearing pacemakers.

• Do not remove the black sheet from the reverse side of the
transceiver (refer to the illustration below). Removal of this
sheet decreases the waterproof effi ciency of the transceiver and
may cause malfunctions if water seeps into the transceiver.

• The orange seal on the reverse side of the transceiver is
important with respect to the waterproof effi ciency of the
transceiver. Do not place stickers or other materials on or
around the seal shown in the fi gure, or on the reverse side of
the battery pack. Doing so will impair the waterproof effi ciency
of the transceiver and may cause it to break down. Additionally,
in order to prevent damage to the seal, do not allow it to come
in contact with foreign materials.

iv

• 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 infl 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
traffi 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 change or charge the battery pack in a hazardous
location. Charge only in fresh air.

• Danger of explosion if the battery is incorrectly replaced;
replace only with the same type.

v

INFORMATION CONCERNING THE BATTERY PACK

The battery pack includes fl ammable objects such as organic solvent.
Mishandling may cause the battery to rupture producing fl 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 fl 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, chain­necklace or hairpins). If the battery pack is short-circuited,
excessive current will fl ow and the battery may generate heat
or smoke, rupture, or burst into fl 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 fl ame.

• Do not leave the battery near fi res, 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
fl ame.

• 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 fl ame.

vi

• Do not charge the battery near fi res 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 fl ame.

• Use only the specifi ed charger and observe charging

requirements!

If the battery is charged in unspecifi ed 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
fl 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
fl 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 fl 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.

• Do not use the battery pack if it is damaged in any way!
The battery may generate heat or smoke, rupture, or burst into

fl 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 fl 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 fl ow upon discharging. The battery may
generate heat or smoke, rupture, or burst into fl ame.

vii

• 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
fl ame.

• 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.

• Do not charge the battery for longer than the specifi ed

time!

If the battery pack has not fi nished charging even after the

regulated time has passed, stop it. The battery may generate
heat or smoke, rupture, or burst into fl 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

fl ame.

• Keep ruptured and leaking battery packs away from fi re!
If the battery pack is leaking (or the battery emits a bad odor),

immediately remove it from fl ammable areas. Electrolyte
leaking from battery can easily catch on fi re and may cause the
battery to generate smoke or burst into fl 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 fl ame.

SCAN

Scan monitors for signals on the transceiver channels. While
scanning, the transceiver checks for a signal on each channel
and only stops if a signal is present.

To begin scanning, press the key programmed as [Scan].

• The icon appears on the display .

• When a signal is detected on a channel, Scan pauses at that
channel. The transceiver will remain on the busy channel until the
signal is no longer present, at which time Scan resumes.

To stop scanning, press the [Scan] key again.

Note: To use Scan, there must be at least 2 channels in the scan
sequence.

TEMPORARY CHANNEL LOCKOUT

During scan, you can temporarily remove specifi c channels
from the scanning sequence by selecting them and pressing

• The channel is no longer scanned. However, when scanning is
ended and restarted, the channels are reset and deleted channels
will again be in the scanning sequence.

PRIORITY SCAN

Note: To use Priority Scan, a Priority channel must be programmed.

When using a single Priority channel, the transceiver will
automatically change to the Priority channel when a call is
received on that channel, even if a call is being received on a
normal channel.

When using dual Priority channels, Priority channel 1 is given
precedence over Priority channel 2. So, if a call is received on
Priority channel 1 while a call is already on Priority channel 2,
