MOBILE INSTALLATION

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.

vibration from loosening the bracket or transceiver.

Initial Installation

• Determine the appropriate angle of the transceiver, using the 3

screw hole positions on the side of the mounting bracket.

Initial Installation

DC POWER CABLE CONNECTION

For best operation, connect directly to vehicle battery.

MOBILE OPERATION

The vehicle battery voltage must be between 11.5 ~ 14.5 Volts

DC. Be sure to use a 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.

2. If using the supplied power cable make sure the entire length of

the cable is dressed so it is isolated from heat, moisture, and the

engine high voltage ignition system.

3. If using the optional Powerwerx TMCG-72 cigarette lighter plug

make sure your cigarette lighter socket in your vehicle can handle

12 VDC @ 12 Amps.

• Conrm 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 length of cable nessary to reach your battery. In

particular, never remove the fuse holders from the cable.

4. Reconnect any wiring removed from the negative terminal.

5. Connect the DC power cable to the transceiver's power supply

connector.

• Press the connectors rmly together until the locking tab clicks.

NOTE

3Initial Installation

• Do not directly connect the transceiver to an AC outlet.

• Use the optional DC Power Adapter (MBXRPA) to connect

the transceiver to a regulated power supply.

• Do not substitute a cable with smaller gauge wires.

BASE STATION OPERATION

In order to use this transceiver for fixed base station operation,

you will need an optional SS-30DV DC power supply and optional

Base Station Enclosure (not included). Please contact your local

dealer for these items.

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.

correct. (Red: positive, Black: negative).

2. Connect the transceiver's DC power connector to

the connector on the DC Power Adapter (MBXRPA).

Press the connectors rmly together until the locking tab clicks.
