NOTICES TO THE USER
WARNING:
Ƈ GOVERNMENT LAW PROHIBITS THE OPERATION OF UNLICENSED TRANSMITTERS WITHIN THE
TERRITORIES UNDER GOVERNMENT CONTROL.
ƇILLEGAL OPERATION IS PUNISHABLE BY FINE AND /OR INPRISONMENT.
Ƈ REFER SERVICE TO QUALIFIED TECHNICIANS ONLY.
SAFETY:
It is important that the operator is aware of, and understands, hazards common to the operation of any transceiver.
WARNING:
ƇEXPLOSIVE ATMOSPHERES (GASES, DUST, FUMES, etc.)
Turn OFF your transceiver while taking on fuel or while parked in gasoline service stations. Do not carry spare
fuel containers in the trunk of your vehicle if your transceiver is mounted in the trunk area.
ƇINJURY FROM RADIO FREQUENCY TRANSMISSIONS
Do not operate your transceiver when somebody is either touching the antenna or standing within 2 to 3 feet
(60 to 90 cm) of it, to avoid the possibility of radio frequency burns or related physical injury.
ƇDYNAMITE BLASTING CAPS
Operating the transceiver within 500 feet (150m) of dynamite blasting caps may cause them to explode.
Turn OFF your transceiver when in an area where blasting is in progress, or where ‘TURN OFF TWO-WAY
RADIO’ sighs have been posted. If you are transporting blasting caps in your vehicle, make sure they are carried
in a closed metal box with a padded interior. Do not transmit while the caps are being placed into or removed
from the container.

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.

PREPARATION
WARNING
Various electronic equipment in your vehicle may malfunction if they are not properly protected from the radio
frecuency
energy which is present while transmitting. Electronic fuel injection,anti-skid braking,and cruise control
systems are typical examples of equipment that may malfunction. If your vehicle contains such equipment,
consult the dealer for the make of vehicle and enlist his/her aid in determining if they will perform while
transmitting.
Note: The following preparation instructions are for use by your KENWOOD dealer,an authorized KENWOOD
service facility, or the factory.
TOOLS REQUIRED
Note: Before installing the transceiver, always check how far the mounting screws will extend below the mounting
Surface. When drilling mounting holes, be careful not to damage vehicle wiring or parts.
The following tools are required for installing the transceiver:
• 1/4inch (6 mm) or larger electriic drill
• 5/32 inch (4.2 mm) drill bit for the 5 x 16 mm self-tapping screws
• 1/8 inch (3.2 mm) drill bit for the 4 x 16 mm self-tapping screws
• Circle cutters
POWER CABLE CONNECTION
CAUTION
•The transceiver operates in 12V negative ground systems only! Check the battery polarity and voltage of the vehicle
before installing the transceiver.
•Do not cut and/or remove the fuse holder from the DC power cable.
1 Check for an existing hole, conveniently located in the firewall, where the power cable can be passed through.
If no hole exists, use a circle cutter to drill the firewall, then install a rubber grommet.
2 Run the two- power cable leads through the firewall and into the engine compartment, from the passenger
compartment.
3 Connect the red lead to the positive (+) battery terminal and the black lead to the negative (-) battery terminal.
Locate the fuse as close to the battery as possible.
4 Coil and secure the surplus cable with a retaining band.
Be sure to leave enough slack in the cables so the transceiver can be removed for servicing while keeping the
power applied.
INSTALLING THE TRANSCEIVER
WARNING
For passenger safety,install the transceiver securely, using the supplied mounting bracket, so the transceiver will
not break loose in the event of a collision.
1 Mark the position of the holes in the dash by using the mounting bracket as a templete. Drill the holes, then
attach the mounting bracket using the supplied self-tapping screws.
Be sure to mount the transceiver in a location where the controls are within easy reach of the user and where
there is sufficient space at the rear of the transceiver for cable connections.
2 Connect the antenna and the supplied power cable to the transceiver.
3 Slide the transceiver into the mounting bracket and secure it using the supplied hex-headed screws.
4 Mount the microphone hanger in a location where it will be within easy reach of the user.
NX-700-K FCC ID: K44378600 / IC: 282F-378600
NX-800-K FCC ID: K44378700
The microp hone and microphone cable should be mounted in a place where they will not interfere with the
safe operation of the vehicle.
CAUTION
When replacing the fuse in the DC power cable,be sure to replace it with a fuse of the same value.
Never replace a fuse with a fuse that has a higher value.

OPERATING BASICSATING
ƇSwitching Power ON/OFF
Press the switch to switch the transceiver ON.
Press and hold the switch for approximately 1 second to switch the transceiver OFF.
ƇAdjusting the Volume
The Volume Up/Down SW control to adjust the volume. You can adjust the volume up sw to increases the volume and
the volume down sw to decreases it.
ƇSelecting a Channel
The Channel Up/Down SW to select a channel.
The channel up sw the channel number increases and The channel down sw decreases it.
ƇTransmitting
Note: Before transmitting, first monitor the channel to make sure it is not already in use.
1 Select your desired channel.
• If the channel is busy, wait until it becomes free.
1 Press the microphone PTT switch and speak into the microphone. Release
the PTT switch when you have finished speaking.
• For best sound quality at the receiving station, hold the microphone approximately 1.5 inches (3~4cm) from
your mouth.
ƇReceiving

2 When you hear a signal, readjust the volume level if necessary.
2 Respond to the call as described in step 2 of “TRANSMITTING”,above.
AUXILIARY FEATURES
ƇTime-out Timer (TOT)
The purpose of the Time-out Timer is to prevent any caller from using a channel for an extended period of time. If you
continuously transmit for a period of time that exceeds the programmed time, the transceiver will stop transmitting and
an alert tone will sound. To stop the tone, release the PTT switch.
Your dealer can program a warning function to alert you before the TOT expires. Continuously transmitting for the
specified by your dealer will cause the warning tone to sound.
MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS
• Use only manufacturer or dealer supplied antennas.
• Antenna Minimum Safe Distance: 120 cm (4 feet), 50% duty Cycle.
• Antenna Gain: 0dBd referenced to a dipole.
The Federal Communications Commission has adopted a safety standard for
human exposure to RF (Radio Frequency) energy which is below the OSHA
(Occupational Safety and Health Act) limits.
• Antenna Mounting: The antenna supplied by the manufacturer or radio dealer
must not be mounted at a location such that during radio transmission, any
person or persons can come closer than the above indicated minimum safe
distance to the antenna, i.e. 120 cm (4 feet) , 50% duty Cycle.
• To comply with current FCC RF Exposure limits, the antenna must be installed
at or exceeding the minimum safe distance shown above, and in accordance
with the requirements of the antenna manufacturer or supplier.
• Vehicle installation: The antenna can be mounted at the center of a vehicle
metal roof or trunk lid, if the minimum safe distance is observed.
• Base Station Installation: The antenna should be À[HGPRXQWHG on an outdoor
permanent structure. RF Exposure compliance must be addressed at the time
of installation.
Antenna substitution: Do not substitute any antenna for the one supplied or
recommended by the manufacturer or radio dealer.
You may be exposing person or persons to excess radio frequency radiation. You
may contact your radio dealer or the manufacturer for further instructions.
Maintain a separation distance from the antenna to person(s) of at least 120 cm (4 feet), 50%
duty Cycle.
