WELCOME

To the world of sophisticated, microprocessor controlled AM/SSB radio communica
tions. Your Uniden PC 122 represents the most advanced mobile type radio ever
designed for use in the Citizens Band Radio Service. It will operate on any of the 40
AM frequencies and Upper and Lower Side Band Frequencies designated by the
Department of Communications. Your PC 122 features a frequency synthesizing
circuit with PHASE LOCK LOOP techniques to assure precise frequency control. This
radio has been type accepted and certified by the D.O.C.

WARNING

Before transmitting with your transceiver, you must obtain a Department of
Communications (D.O.C.) Citizens Radio Licence. Obtain an application
form, from the D.O.C, Before completing the form you should read the
conditions governing the licensing and operation of the C.R.S. (D.O.C.
brochure RB 249). This brochure also can be obtained from the D.O.C. After
completing the application form, mail it with the appropriate fee to the
Superintendant Regulatory of Licensing in the State or territory in which the
station will be operated.

MOBILE INSTALLATION

Plan the location of the radio and microphone bracket before starting 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 securely fastened to a solid
surface using the mounting bracket and self-tapping screws which are provided,

MOBILE ANTENNA

Since the maximum allowable power output of the transceiver is limited by the
D.O.C., the antenna is a very important factor affecting transmission distance. It is
for this reason that we strongly recommend that you install only a quality antenna in
your new CB radio system. You have purchased a superior quality transceiver. Don't
diminish its performance by installing an inferior antenna.

Only a properly matched antenna system will allow maximum power transfer from me
50-ohm transmission line to the radiating element. We recommend that you use an
SWR meter when installing your antenna. Set your PC 122 to channel 20 and adjust to
SWR — 1, Your SANTRONIC dealer is qualified to assist you in the selection of the
proper antenna to meet your application requirements.

For automobile installation, the whip antenna may be used with good effect. The most
efficient and practical installation is a full quarter 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 automobile,
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 prevention of electrolysis between fittings on the hull and
water.

CONNECTING THE POWER CORDS

With regard to the connection of the power cords, it may be possible or desirable to
connect the red lead (for negative ground systems) or the black lead (for positive
ground systems) to the ignition switch accessory terminal so that the radio is auto
matically turned off when the ignition switch (key) is turned off.

Alternately, the power lead may be connected to an available terminal on the fuse
block or even to a point in the wiring harness. Care must be taken, however, to guard
against a short circuit condition. When in doubt, please contact your vehicle dealer for
specific information for your vehicle.

GROUND INFORMATION

A negative ground system is generally identified by the " — " battery terminal being
connected to the vehicle motor block, but if you cannot determine the polarity of
your vehicle, consult your vehicle dealer for information.

NOTE: This radio may be installed and used in any 12-volt DC negative or positive
ground system.

NEGATIVE GROUND SYSTEM

If you are operating on a negative ground system, connect the red DC power cord
from the radio to the positive "+" battery terminal or other convenient point and
connect the black power lead to the chassis or vehicle frame, or the negative " — "
terminal of the battery.

POSITIVE GROUND SYSTEM

If you are operating on a positive ground system, connect the black DC power cord
from the radio to the negative " — " battery terminal or other convenient point and
connect the red power lead to the chassis or vehicle frame, or the positive " -t "
terminal of the battery.
