INSTALLATION
An extremely important requirement is the ease of installation and re-
moval for those occasions when you might want to remove the unit for
service and maintenance.
The most common mounting position for a transceiver is under the da-
shboard directly over the drive shaft hump. Do not mount the transceiver
in the path of the heater or air conditioning.
Take your time and plan your installation carefully. When you have de-
termined the best location for mounting, use the mounting bracket as a
template to mark mounting holes. Take care when you drill the holes that
you do not drill into wiring, trim or other accessories.
Mount in position with bolts, lock washers and nuts or self-threading
screws.
Insert the power cable with lighter plug into the vehicle’s cigarette lighter
cord.
Before operating, you must install and connect your antenna system. The
lead from the antenna you’ve installed should be connected to the an-
tenna coaxial connector. If you are using an external speaker, connect it
to the EXT-SPKR jack.
INSTALLING AN ANTENNA
A mobile antenna system is not limited to the antenna only. The transmis-
sion line, as well as the vehicle, are important factors in the total anten-
na system. Therefore, you must use the correct type of transmission line
and mount the antenna securely in a position that will give you optimal
results.
Use coaxial cable with an impedance of 50 Ohms. Generally speaking,
you should keep the length of the transmission line to a minimum.
The above discussion is as important for reception as it is for the transmis-
sion. If a mismatch exists between the antenna and the receiver, the
excellent sensitivity and signal-to-noise radio of the receiver circuit will
be defeated.
Useful information
1. Place the antenna as high as possible
2. The longer the antenna is, the better will be the performance
