
This radio generates RF electromagnetic energy during transmission.
This radio is designed for and classified as “Occupational Use Only”,
meaning it must be used only during the course of employment by
individuals aware of the hazards, and the ways to minimize such
hazards.This radio is NOT intended for use by the “GeneralPopulation”
in an uncontrolled environment.
For compliance with FCC and Industry Canada RF Exposure
Requirements, the transmitter antenna installation shall comply with the
following two conditions:
1.The transmitter antenna gain shall not exceed 0 dBi.
The antenna is required to be located outside of a vehicle and kept at
a distance of 63 centimeters or more between the trans-mitting
antenna of this device and any persons during operation.For small
vehicle as worst case, the antenna shall be located on the roof top at
any place on the centre line along the vehicle in order to achieve 63
centimeters separation distance. In order to ensure this distance
is met, the installation of the antenna must be mounted at least 63
centimeters away from the nearest edge of the vehicle in order to protect
against exposure to bystanders.

To ensure that your exposure to RF electromag-netic energy is within
the FCC allowable limits for occupationaluse, always adhere to the
following guidelines:
DO NOT operate the radio without a proper antenna attached, as
this may damage the radio and may also cause you to exceed FCC
RF exposure limits. A proper antenna is the antenna supplied with this
radio by the manufacturer or an antenna specifically authorizedby the
manufacturer for use with this radio.
In order to comply with RF exposure
requirements, a minimum distance of 200 cm must be maintained between
the antenna and all persons
DO NOT transmit for more than 50% during the time of employment
(50% duty cycle or less). Transmitting excessive amount of time can
cause RF exposure compliance requirements to be exceeded. Please
carefully read this instruction manual to learn how to transmit and stop
transmitting before starting to use it.

During transmissions, your radio generates RF energy that can
possibly cause interference with other devices or systems. To avoid
such interference, turn off the radio in areas where signs are posted to
do so. DO NOT operate the transmitter in areas that are sensitive to
electromagnetic radiation such as hospitals, aircraft, and blasting sites.

This product is used in situations that users are exposed to RF as
consequence of their employment provided those users are fully aware
of the potential RF hazards and can exercise control over their exposure.
This transceiver is NOT ATEX approved and NOT intended for the use
in hazardous explosive atmospheres.

Mobile Operation
The vehicle battery must have a nominal rating of 12V. Never
connect the transceiver to a 24V battery. Be sure to use a 12V
vehicle battery that has sufficient current capacity. If the current
to the transceiver is insufficient, the display may darken during
transmission, or transmitting output power may drop excessively.
When the ignition key is turned to ACC or ON position with the
8.
radio's power switch on, the unit turns on automatically and the
power switch will be lit. Turn the ignition key to OFF position or
manually turn the power switch off to shut down the radio.
Using extra cable,power consumption:5MAH.

Without this function,user can turn on/off radio by Power knob.
10.
Route the DC power cable supplied with the transceiver directly

to the vehicle's battery terminals using the shortest path from the
transceiver.
Never use the cigarette lighter socket as a DC source.

The entire length of the cable must be dressed so it is isolated from

heat, moisture, and the engine secondary (high voltage) ignition
system/ cables.
After installing cable, in order to avoid the risk of damp, please
2.
use heat-resistant tap to tie together with fuse box. Don't forget to
reinforce whole cable.
In order to avoid the risk of short circuit, please cut down


connections.
In order to use this transceiver for fixed station operation, you will
need a separate 13.8V DC power supply (not included) , Please
contact local dealer to require.
The recommended current capacity of your power supply is 12A or more.
Connect the DC power cable to the regulated DC power supply
1.
and ensure that the polarities are correct. (Red: positive, Black:
negative).
Never directly connect the transceiver to an AC outlet.

Use the supplied DC power cable to connect the transceiver to a

regulated power supply.
Do not substitute a cable with smaller gauge wires.

Connect the transceiver's DC power connector to the connector
2. on
the DC power cable.
Press the connectors rmly together until the locking tab clicks

3Initial Installation
REPLACING FUSES
If the fuse blows, determine the cause, then correct the problem.
After the problem is resolved, replace the fuse. If newly installed fuses
continue to blow, disconnect the power cable and contact your dealer
for assistance.
Only use fuses of the specified type and rating, otherwise the
transceiver could be damaged.
After connecting the transceiver to the power supply, the supply voltage
can be displayed on LCD by pressing the FUN key together with the
MONI
key.
The display immediately changes as the voltage supply changes, It
also displays voltage during transmission.
The transceiver will return to its normal operation when the power is
switched ON or repeat above operation.
Before operating, install an efcient, well-tuned antenna. The success
of your installation will depend on the type of antenna and its correct
installation.
Use a 50Ω impedance antenna and low-loss coaxial feed-line that
has a characteristic impedance of 50 Ω, to match the transceiver input
impedance. Coupling the antenna to the transceiver via feed-lines having
an impedance other than 50Ω reduces the efficiency of the antenna
system and can cause interference to nearby televisions, radio receivers
and other electronic equipment.
Fuse Location Fuse Current Rating
Transceiver 15A
Supplied Accessory DC
power cable 20A
If you use the transceiver for a long period when the vehicle battery is
not fully charged, or when the engine is OFF, the battery may become
discharged, and will not have sufcient reserves to start the vehicle. Avoid
using the transceiver in these conditions.
The range of displayed voltage is only from 7V to16V DC. Because the
displayed value is estimated, please use a voltmeter when a more precise
reading is desired.
Power supply voltage Display
Antenna Connection
Important
Transmitting without first connecting an antenna or other matched
load may damage the transceiver. Always connect the antenna to the
transceiver before transmitting.
All xed stations should be equipped with a lightning arrester to reduce
the risk of re, electric shock, and transceiver damage.

Microphone
If you plan to use an external speaker, choose a speaker with an
impedance of 8 Ω. The external speaker jack accepts a 3.5 mm (1/8")
mono (2-conductor) plug.
For voice communications, connect a microphone equipped with
an 8-pin modular plug into the modular socket on the front of the
main unit. Press rmly on the plug until the locking tab clicks. Attach
the supplied microphone hanger in an appropriate location using the
screws included in the screw set.
External speaker adopt double port BTL, please care about the connection.
The speaker can not connect with the ground, otherwise the speaker will be
fault.

According to the option selected during
installation, press the switch or turn the
ignition key to ACC (speed up) or ON (startup)
position to power on. Press the key for 1s or
turn the ignition key to OFF position to turn off.
A squelch eliminates white-noise (the background noise when a signal
is not received). Higher level settings will keep the squelch "closed” more
tightly for quieter monitoring, but weak signals will not be heard. Lower
settings allow weaker signals to "open” the squelch but noise may also
cause it to open. By rotating the SQL knob, adjust the squelch level to
the desired level.
