Technical diagram of a vehicle interior showing dashboard, steering wheel, and control panel (no text or labels)

AVOID mounting the transceiver where:

a) Hot or cold air can blow directly on the unit.
b) Normal operation of the vehicle may be hindered.
c) Excessive vibrations are present.

Technical line drawing of a mechanical device with two views: top shows a mounted device, bottom shows a cylindrical device with a 18° angle indicator (no text or symbols present)

Securely mount the transceiver with the supplied bracket to minimize vibrations.

The installation angle of the IC-1200A/E can be varied by approximately 18^ . Adjust the angle for the clearest view of the transceiver.

To protect the mic connector cable from damage, the MIC CONNECTOR MUST BE attached to the microphone connector support.

DO NOT use the cigarette lighter socket for power connections.

To prevent the voltage from dropping, solder or crimp the cable lag when connecting the power cable to the battery.

- ANTENNA

Transceiver performance largely depends on the quality of the antenna used. Select a high-quality antenna and use it as recommended by the manufacturer.

●TYPE-N CONNECTOR INSTALLATION

A: Roof-mount antenna

- Best location for a good radiation pattern. - Drill a hole in the roof, or use a magnetic antenna base.

B: Gutter-mount antenna

C: Trunk-mount antenna

D: Bumper-mount antenna

- Best location for longer antennas.

A TYPE-N connector should be used on the feedline to minimize power loss at UHF frequencies. Follow the instructions below for best results when installing the connector.

●BASE STATION USE

1) Slide the nut, washer, and rubber gasket over the coaxial cable and cut the end of the cable evenly.

2) Cut and remove 15mm of the outer vinyl jacket, and fold the braid back over the clamp. The clamp end should be flush with the end of the vinyl jacket. Evenly trim the braid ends.

Cut and remove 6mm of the dielectric (the center conductor insulation).

3) Soft-solder the center conductor. Install a center conductor pin and solder it.

4) Carefully slide the plug body into place aligning the center conductor pin on the cable with the hole in the insulator inside the plug body.

Complete the assembly by screwing the nut into the plug body.

When using the IC-1200A/E as a base station, be careful of the following points:

• POWER SUPPLY

Use a 13.8V power supply with more than 5.5A. The optional PS-45 AC POWER SUPPLY is available and can be used with an optional OPC-102 cable.

• COAXIAL CABLE

With a coaxial cable the strength of 1200MHz band signals diminishes, so be sure to use a 50Ω coaxial cable as short and thick as possible.
