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 CONNECTION
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 cable plug to the standard receptacle on the rear
panel. Most antennas are terminated with a type PL-259 plug and mate
with the receptacle.
3. Connect the red DC power input wire (with the fuse) to +13.8V DC.
This wire extends from the rear panel. In automobile 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.
