DB477C

Version 3

Thank you for choosing this vehicle transceiver,

always strives to provide high quality products, And this transceiver is

no exception. As you learn how to use this transceiver, you will nd that

your unit is very user friendly. For example, each time you

select a menu item, you will see a text message on the display that lets

you know what you are conguring.

Though it is user friendly, 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 a Crystal

service agent or your dealer.

Please observe the following precautions to prevent re, 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.

1. Install the mounting bracket in the vehicle using the supplied self-

tapping screws (4pcs) and at washers (4pcs).

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.

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, 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 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), 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).

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.

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. Using extra cable, power consumption:5MAH.

10.

Without this function, user can turn on/off radio by Power knob.

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

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 autho-

rized dealer or an authorized service

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 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.

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.

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:
