SAFETY TRAINING

WARNING:

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
indiv iduals aw are of th e hazards, and the w ays to mi nimize su ch
hazards.This radio is NOT intended for use by the “GeneralPopulation”
in an uncontrolled environment.

• Fo r c omp lia nce wit h F CC and Ind ust ry Can ada RF Exp osu re

Requirements, the transmitter antenna installation shall comply with
the following two conditions:

1.The transmitter antenna gain shall not exceed 0 dBi.

2.The antenna is required to be located outside of a vehicle and kept at

a distance of 63 centimeters or more between the transmitting

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.

CAUTION:

To ensure that your exposure to RF electromagnetic energy is within

the FCC allowable limits for occupational use, 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

INFORMATION

radio by the manufacturer or an antenna specically authorized by the

manufacturer for use with this radio.

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.

Electromagnetic Interference/Compatibility

Du ring tra nsm iss ion s, your rad io gen erate s R F e nergy 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.

Occupational/Controlled Use

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.

Initial Installation

DC Power Cable Connection

Mobile Operation

The v ehicle batter y must have a nominal ra ting 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.

Route the DC power cable supplied with the transceiver directly

1.

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

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 sp ecified type an d rating, otherwi se the
transceiver could be damaged.

If you use the transceiver for a long period when th e 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.

Antenna Connection

Before operating, install an efficient, 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 lo w-los s 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.

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.

Accessories Connections

External Speaker

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.

External speaker adopt double port BTL, please care about the connection.
Do not use the speaker that requires grounding.

Microphone

For voice communications, connect a provided microphone into the

ADJUSTING SQUELCH LEVEL

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.

Receiving

Select the desired receiving frequency
or browse channels to listen to ongoing
communications. The S-meter shows relative
signal strength between BUSY and 5th segment when the transceiver
detects an incoming signal.

CTCSS/DCS Encode and Decode setup

Many repeaters require a CTCSS tone or a DCS code encode
setting as a “key” to access the system, so-called “selective-calling”.
Sometimes, CTCSS or DCS decode features are used on the output of
a repeater so they can be used as a squelch. In this mode, regardless
of the main squelch status, the audio can be heard ONLY when the
matching tone/code signal is received. The combination of CTCSS
squelch and DCS function is not available; only one or the other may
be used for a given channel.The operation is available on VFO and
memory mode. Dealer-Preprogrammed units can't operate this function
manually. In the memory mode, the setting is temporary; changing the
channel or turning off the radio will erase the setting.

Press

key. The current setting will be displayed with T/SQ/

1.

DCS icons and relative frequency/code. Press the same key to
select T/SQ/DCS setting.

The numbers (such as 88.5) represent the CTCSS frequency in

2.

Hz. When it is displayed with the icon only, the unit transmits
the sub-audible tone while the PTT
is pressed (encode) and the repeater
access is en a b l e d (assuming th e
repeater is using 88.5Hz tone).

Press the same key again so that the

This is the CTCSS decode frequency.
This enables CTCSS squelch (or Tone
Squelch, TSQ).

Press it again so that the 3-digit number

and icon is displayed. This is the DCS code, and it enables
DCS encoding and decoding.

For 2-4, rotate the main dial or press the [
change tone or code. Press any key ( Except FUNC / PWR / TS / DCS,

/ ] keys to

T/SQ/DCS icon will remain on the display to show the current selective-

calling status. To exit, simply use the TS/DCS key and press it until the
relative status icon T/TQ/DCS disappears.

The CTCSS encoding and decoding frequencies may be set differently.
The encode settin g frequency automatically relates to the dec ode
setting, but decode setting does not affect encode. The standard set of
50 different CTCSS tones are available. DCS encode/decode cannot be
separated. The list of selectable tones and codes is shown on Appendix
at the end of this booklet.
