Thank you for choosing this vehicle transceiver,
always provides high quality products, And this transceiver is no
exception. As you learn how to use this transceiver, you will find that
is pursuing "user friendliness". For example, each time you
change the menu no. in Menu mode, you will see a text message on the
display that lets you know what you are conguring.
Though friendly design for user, this transceiver is technically
complicated and some features may be new to you. Consider this
manual to be a personal tutorial from the designers,allow the manual to
guide you through the learning process now, then act as a reference in
the coming years.
Do not attempt to configure your transceiver while driving,it is
dangerous.
This transceiver is designed for a 13.8V DC power supply. Don't use
a 24V battery to power on the transceiver.
Do not place the transceiver in excessively dusty, humid or wet
areas, nor unstable surfaces.
Please keep it away from interferential
devices (such as TV, generator etc.)
Do not expose the transceiver to long
periods of direct sunlight nor place it close
to heating appliances.
If an abnormal odor or smoke is detected
coming from the transceiver, turn OFF the
power immediately. Contact an Anytone
service station or your dealer.
Do not transmit with high output power for extended periods; the
transceiver may overheat.
Please observe the following precautions to prevent fire, personal
injury, or transceiver damage:

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.
Install the mounting bracket in the vehicle using the supplied self-
1.
tapping screws (4pcs) and at washers (4pcs).
Position the transceiver, then insert and tighten the supplied
2.
hexagon SEMS screws.
Double check that all screws are tightened to prevent vehicle
vibration from loosening the bracket or transceiver.

Mobile Operation
In many cars,the cigar-lighter plug is always powered. If this is the case, you
cannot use it for the ignition key on/off function.
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(Start) position with
7.
the radio turned off, the power switch illuminates. The illumination
will be turned off when the ignition key is turned to the off position.
Route the DC power cable supplied with the transceiver directly
1.
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.
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
3.
connection 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.
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.
Reconnect any wiring removed from the negative terminal.
5.
optional QCC-01(For Cigar-Plug connection) cable. Connect one of
the cables between the ACC terminal or a Cigar-Plug that operates
with the vehicle ignition or ACC switch on the vehicle and EXT

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 xed 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.
Connect the DC power cable to the regulated DC power supply
1.
and ensure that the polarities are correct. (Red: positive, Black:
negative).
Do not 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.
To turn on the unit, press the power switch manually while it is
illuminated. (While ignition key is at ACC or ON position)
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:
9. 5mAh.
Without this function,user can turn on/off radio by Power knob.

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 autho-
rized dealer or an authorized servi-center 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
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 efcient, 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 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 broadcast television
receivers, radio receivers, and other electronic equipment.

Transceiver 15A

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 sufcient 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.
The possible locations of antenna on a car are shown as following:

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.
To utilize the optional FR488 software, you must rst connect the
transceiver to your PC then using an optional programming cable
PC50 (via Data socket ).
Please use FR488 software for programming.
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.
Ask your dealer about purchasing a Programming Cable PC50.
