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

DC Power Cable Connection
Mobile Operation
In some cars,the 12V 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.
7. When the ignition key is turned to ACC or ON (Start) position with
the radio turned off, the power switch illuminates. The illumination
will be turned off when the ignition key is turned to the off position.
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, to avoid the risk of moisture, please use
heat-resistant tape to tie together with fuse box. Don't forget to
reinforce whole cable.
3. In order to avoid the risk of short circuit, please remove negative (-)
terminal 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.
5. Reconnect any wiring removed from the negative terminal.
optional 12V Plug cable. Connect one of the cables between the ACC
terminal or a 12v Plug that operates with the vehicle ignition or ACC
switch on the vehicle and EXT POWER jack on the rear side of the
unit.
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). Please
contact your local dealer to purchase.
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).
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 (not supplied).
Do not substitute a cable with smaller gauge wires.
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.
To turn on the unit, press the power switch manually while it is
illuminated. (While ignition key is at ACC or ON position)
8. When the ignition key is turned to ACC or ON position with the
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.
9. When using extra cable, power consumption: 5 mAH.
10.
Without this function, user can turn on/off radio by Power knob.

Initial 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
authorized Crystal M dealer or an authorized Crystal M service center
for assistance.
Only use fuses of the specified type and rating, otherwise the
transceiver could be damaged.
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.
Fuse Location Fuse Current Rating
Transceiver 10A
Supplied Accessory DC
power cable 10A
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.
Antenna Connection
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:

Getting Acquainted
Microphone
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.
