To install the transceiver, select a safe, convenient location inside your
vehicle that minimizes danger to your passengers and yourself while the
vehicle is in motion. Consider installing the unit at an appropriate position
so that knees or legs will not strike it during sudden braking of your
vehicle. Try to pick a well ventilated location that is shielded from direct
sunlight.
Double check that all screws are tightened to prevent vehicle

vibration from loosening the bracket or transceiver.

2. Position the transceiver, then insert and tighten the supplied
hexagon SEMS screws.
DC Power Cable Connection
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.
1. Route the DC power cable supplied with the transceiver directly
to the vehicle's battery terminals using the shortest path from the
transceiver.
We recommend you do not use the cigarette lighter socket as

some cigarette lighter sockets introduce an unacceptable voltage
drop.
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.
2. After installing cable, in order to avoid the risk of damp, please
use heat-resistant tap to tie together with fuse box. Don't forget to
reinforce whole cable.
3. In order to avoid the risk of short circuit, please cut down
connection with negative (-) of battery, then connect with radio.
4. Confirm the correct polarity of the connections, then attach the
power cable to the battery terminals; red connects to the positive (+)
terminal and black connects to the negative (-) terminal.
Use the full length of the cable without cutting off excess even if

the cable is longer than required. In particular, never remove the
fuse holders from the cable.
1. Install the mounting bracket in the vehicle using the supplied self-
tapping screws (4pcs) and at washers (4pcs).
Locate the power input connector as close to the transceiver as
possible.

Initial Installation
Before connecting the DC power to the transceiver, be sure to switch

the transceiver and the DC power supply OFF.
Do not plug the DC power supply into an AC outlet until you make all

connections.
In order to use this transceiver for fixed station operation, you will
need a separate 13.8V DC power supply (not included), power
supply( QRP-01) as optional accessories. Please contact local dealer
to require.
The recommended current capacity of your power supply is 12A.
1. Connect the DC power cable to the regulated DC power supply
and ensure that the polarities are correct. (Red: positive, Black:
negative).
2. Connect the transceiver's DC power connector to the connector on
the DC power cable.
Press the connectors rmly together until the locking tab clicks
.
Fixed Station Operation
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 autho-
rized dealer or an authorized servi-
cecenter for assistance.

Initial Installation
Only use fuses of the specified 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.
Before operating, install an efcient, well-tuned antenna. The success of
your installation will depend largely on the type of antenna and its correct
installation. The transceiver can give excellent results if the antenna
system and its installation are given careful attention.
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 broadcast television
receivers, radio receivers, and other electronic equipment.
Antenna Connection
Transmitting without rst 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.
The possible locations of antenna on a car are shown as following:
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.
External speaker adopt double port BTL, please care about the
connecting way. The speaker can not connect with the ground,
otherwise the speaker will be fault. The wrong connecting way as
the following picture.

Initial Installation

Choose an suitable location to install the microphone hanger.
1. Use the microphone hanger to locate the position for the
screws.
2. Use the screws and pads to x the microhone hanger.
To utilize the optional AT-778 software, you must first connect the
transceiver to your PC then using an optional programming cable
PC55 (via Data socket ).
Please use AT-778V/U software for programming.
Ask your dealer about purchasing a Programming Cable PC55.
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 irmly on the plug until the locking tab clicks.
