DC Power Cable Connection



Initial Installation

Mobile Operation

The vehicle battery must have a nominal rating of 13.8V. Never
connect the transceiver to a 24V battery. Be sure to use a 13.8V
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
system/cables.

After installing cable, in order to avoid the risk of damp, please use

2.

3

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 connec-

3.

tion with negative (-) of battery, then connect with radio.

Confirm the correct polarity of the connections, then attach the

4.

power cable to the battery terminals; red connects to the positive (+)
terminal and black connects to the negative (-) terminal.

▼

Never remove the fuse holders from the cable.

Reconnect any wiring removed from the negative terminal.

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 specied type and rating, otherwise the transceiver

could be damaged.

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.

External Speaker

If you plan to use an external speaker, choose a speaker with an

impedance of 8Ω. The external speaker jack accepts a 3.5mm (1/8")

mono (2-conductor) plug.

5

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 low-loss coaxial feed-line that
has a characteristic impedance of 50Ω, 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.

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
socket on the front of the main unit. Turn the ring firmly on the plug
until it locks. Attach the supplied microphone hanger in an appropriate
location using the screws included in the screw set.

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. Dealer­Preprogrammed 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 [TS/DCS/LOCK] key. The current setting will be displayed

1.

with T/SQ/DCS icons and relative frequency/code. Press the same

Offset Direction and offset frequency setup



Repeater receives a signal(UP-LINK) on one frequency and re-transmits
on another frequency(DOWN-LINK). The difference between these two
frequencies is called the offset frequency. If the UP-LINK frequency
higher than DOWN-LINK frequency, the direction is positive, If it is lower,
the shift direction is negative.
