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.
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
onlya 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 maximumpower transfer
from the 50-ohm transmission line to
the radiating element. Yourlocal dealer
isqualified 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-
bile, although the efficiency isless than
a full quarter wave whip antenna.
For marine installation, consult your
dealer for information regarding an
adequate grounding system and pre-
vention of electrolysisfittingsbetween
the hulland water.
CONNECTING THE POWER CORDS
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) isturned
off.
Alternately, the power lead maybe 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 forspecificinfor-
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.
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
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
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
other convenient point, and connect
the red power leadto the chassisor ve-
hicleframe,or (+) battery terminal.
