INSTALLATION
MOBILE INSTALLATION
Plan the location of the radio and micro­
phone bracket before starting instailation,
Seiect a location that is convenient for op­
eration and does not interfere with the
driver or passenger in the vehicie. The mic
hanger bracket shouid be secureiy
fastened to a soiid surface using the seif­
tapping screws which are provided. The
button on the back of the radio wiil siide
into the mic hanger to hoid it secureiy in
place.
Mobile Antenna
If another external antenna is desired con­
sult your local CB Dealer for a com­
patible model. 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
the 50-ohm transmission line to the radiat­
ing element. We recommend that you
have your system checked with an SWR
meter when installing your antenna. Vbur
local dealer is qualified to assist you in
the selection an installation of a proper
antenna
to meet your application
requirements.
Connecting the Power
Since the maximum allowable power out­
put of the transceiver is limited by the
D.O.C, the antenna is a very important fac­
tor afferting transmission distance. The
magnetic mount base and screw-in teles­
copic antenna will provide maximum range
when properly installed.
Screw the antenna into the base. Place the
base on a flat metallic area of your vehicle
roof. The center of the roof is ideal for 360“
transmission. Feed the coaxial cable thru a
window or door. With the battery pack off,
connect the antenna to the bottom of the
unit.
Connect the power cord to the jack on the
bottom of the unit [battery pack must be
removed). Plug the cord into the cigarette
lighter of your vehicle. The PRO 31 Oe may
also be connected directly to the fuse
block
with the proper wiring (not
included).
IMPORTANT - The cigarette lighter plug
is designed to be used with negative
ground vehicles. Do not attempt to oper­
ate the unit with the power cord con­
nected to a positive ground vehicle.
Ground Information
Most newer cars and smali trucks use a ne­
gative ground system, while some older
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. If you cannot de­
termine the polarity ofyour vehicle, consult
your vehicle dealer for information.
Positive Ground System
If you are operating on a positive ground
system, the unit must be wired directly to
the fuse block. Connect the black lead
from the radio to the negative bat­
tery terminal or other convenient point
and connect the red power lead to the
chassis or vehicle frame, or the positive
" + " terminal of the battery.
Cord Holder
install the cord holder with ANT. iabei
on right-hand side and PWR. Iabei on
left-hand side as shown. Match key (A)
with notch (B) as illustrated.
While pressing the cord-holder's upper
and lower sides, insert the cord holder
securely into the grooves at the bottom
ofyour PRO 31 Oe. Cord holder will snap
into place when pressure is released.
PORTABLE USE
The PRO 3I0e can operate under its
own battery power. The snap-on bat­
tery pack included withyour unit makes
it a true Emergency CB. It also makes a
great portable CB for long range com­
munications outdoors.
Installing the Batteries and Bat­
tery Pack
Hold the battery pack in one hand and
press on the top of the pack where indi­
cated. The battery holder will slide out.
install 8 "AA" size nonrechargeable
batteries. Slide the battery holder back
into the battery pack until it is flush
with the bottom. Slide the battery pack
onto the bottom of the radio from left to
right until it snaps in place. Make sure
the slots on the battery pack and the ra­
dio fit correctly.
NOTE: When the batteries become weak
the battery LED will light. Be sure to
replace the batteries as soon as possible.
You can preserve battery power by select­
ing the LOW position on HI/LOW switch.
The LOW setting has substantially shorter
transmission range.
Connecting the Antenna
For portable use the telescopic antenna
will give good results. Simply unscrew it
from the magnetic mount base and
screw it into the antenna connector on
the top of the unit. Fully extend the an­
tenna for maximum range.
HI/LOW Switch
The PRO 3I0e has a transmission power
selector switch - HI/LOW. In the HI posi­
tion the unit win transmit at the higher
output power and achieve longer range.
In the LOW positron the transmission
output power (range) is substantially
reduced; however, the battery life will be
increased. For longer range select the HI
position. For maximum battery life select
the LOW position.
