Installation
LOCATION
Plan the location of the transceiver and microphone bracket before starting the
installation. Select a location that is convenient for operation and does not interfere
with the driver or passengers in the vehicles. In automobiles, the transceiver is
usually mounted below the dash panel, with the microphone bracket beside it.
MOUNTING THE RADIO
Your transceiver is supplied with a universal mounting bracket. When
mounting the bracket and radio to your car, make sure it is mechanically strong.
Also provide a good electrical connection to the chassis of the vehicle. Proceed as
follows to mount the transceiver:
1. After you have determined the most convenient location in your vehicle, hold
the transceiver with mounting bracket in the exact location desired. If nothing
will interfere with mounting it in the desired position, remove the mounting
bolts. Before drilling the holes, make sure nothing will interfere with the
installation of the mounting bolts.
2.
Connect the antenna coax connector to the standard antenna connector on the
rear panel of the radio. Most antennas are terminated with a type PL-259
connector.
3. Connect the red DC power input wire (with the fuse) to +13.8V DC. This wire
extends from the rear panel. In automatic installation, +13.8V DC is usually
obtained from the accessory contact on the ignition switch. This prevents the
set being left on accidentally when the driver leaves the car and also permits
operating the unit without the engine running. Locate the accessory contact on
most ignition switches by tracing the power wire from the AM broadcast
receiver in the car.
4. Connect the black lead to –13.8V DC. This is usually the chassis of the car.
Any convenient location with good electrical contact (remove paint) may be
used.
5. Mount the microphone bracket on the right side of the transceiver or near the
transceiver, using two screws supplied. When mounting in an automobile,
place the bracket under the dash so the microphone is readily accessible.
