INSTALLATION

MOBILESTATION INSTALLATION

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 passenger in the vehicle. The radio should be secure-

lyfastened to some solid face, using the mounting bracket and self-tapping screws which are provided.

bile, although the efficiency is less than a full quarter wave whip antenna.

For marine installation, consult your dealer for information regarding an adequate grounding system and pre-

vention of electrolysisfittings between the hulland water.

CONNECTING THE POWER CORDS

A negative ground system is generally identified by the (-) battery terminal being connected to the vehicle motor block, but ifyou cannot determine the polarity of your vehicle, it is suggested

that you consult your vehicle dealer for definite information.

NEGATIVE GROUND SYSTEM

convenient point and connect the black power lead to the chassis or vehicle frame, or (-) battery terminal.

POSITIVE GROUND SYSTEM

If you are operating on a positive ground system, connect the black DC powercordfrom the transceiverto the

negative, or (-), battery terminal or

MOBILE STATION ANTENNA

Since the maximum allowable power output of the transmitter is limited by the D.O.C., the antenna is a very im-

portant factor affect'ing transmission distance. It is for this reason that we

strongly recommended that you install only a quality antenna inyour new citiz- ens band system. You have just pur- chased a superior transceiver. Don't di-

minish its performance by installing an inferior antenna.

Only a properly matched antenna sys-

tem will allow maximum power transfer from the 50-ohm transmission line to

the radiating element. Your local dealer is qualified to assist you in the selection of the proper antenna to meet your ap- plication requirements.

For automobile installation, the whip antenna may be used with good effect. The most efficient and practical installa- tion isa fullquarter wave whip antenna mounted on the rear deck or fender top midway between the rear window and bumper.

A short "loaded" whip antenna is more convenient to install on your automo-

With regard to the connection of the power cords, it may be possible or desir- ; able to connect the (red lead for nega- tive ground system) or (black lead for positive ground system) to the ignition switch accessory terminal so that the transceiver is automatically turned off

when the ignition switch (key) is turned off.

Alternately, the power lead may be con- nected to an available terminal on the

fuse block or even to a point in the wir- ing harness. Care must be taken, how- I ever, to guard against a short circuit, condition. When in doubt, please con- tact your vehicle dealer for specific infor- mation for your vehicle.

GROUND INFORMAnON

NOTE: This transceiver may be in- ) stalled and used in any 12-volt DC ne- ' gative or positive ground system vehicle.

Most newer cars and small trucks use a

negative ground system, while some ol- der cars and some newer, larger trucks may use a positive ground system.

If you are operating on a negative ground system, connect the red DC power cord from the transceiver to the positive, or (+) battery terminal or other

other convenient point, and connect the red power leadto the chassisor ve-

hicleframe, or (+) battery terminal.
