INSTALLATION

1.

LOCATION

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.

In

automobiles,

the

transceiver

is

usually

mounted

to

the

dash

panel

with

the

microphone

bracket

beside

it.

2.

MOUNTING

AND

CONNECTION

This

radio

is

supplied

with

a

universal

mounting

bracket.

The

transceiver

is

held

in

the

bracket

by

the

four

thumb

screws.

supplied,

permitting

adjustment

to

the

most

convenient

angle.

The

bracket

must

be

mounted

with

the

screws

supplied.

The

mounting

surface

must

be

mechanically

strong.

Proceed

as

follows

to

mount

the

transceiver

:

a)

After

you

have

determined

the

most

convenient

location

in

your

vehicle,

hold

the

radio

with

the

mounting

bracket

in

the

exact

location

desired.

If

nothing

interferes

with

mounting

it

in

the

desired

position,

remove

the

~unting

bracket

thumb

screws

and

mark

the

mounting

holes

using

the

bracket

as

a

template.

Before

drilling

the

holes,

~e

sure

nothing

will

interfere

with

the

installation

of

the

mounting

screws.

Drill

the

holes

and

mount

the

bracket

and

then

install

the

radio.

b)

Connect

the

antenna

cable

plug

to

the

standard

receptacle

on

the

rear

panel.

Most

CB

antennas

are

terminated

with

a

type

PL-259

plug

which

mates

with

the

receptacle

on

the

rear

panel.

c)

.Connect

the

DC

power

input

wire

with

the

fuse

(red)

to

+12V

DC.

This

wire

extends

from

a

plug

which

connects

to

the

rear

panel.

ln

automobile

installations,

+12V

DC

is

usual-

ly

obtained

from

the

accessory

contact

on

the

ignition

switch.

This

prevents

the

set

being

left

on

accidentally

when

the

driver

leaves

the

car

and

also

permits

operating

the

radio

without

the

engine

running.

You

can

locate

the

I

)

)

accessory

contact

on

most

ignition

switches

by

tracing

the

power

wire

from

the

AM

broadcast

receiver

in

the

car.

d)

Connect

the

black

wire

to

ground.

This

is

usually

the

chassis

of

the

car.

Any

convenient

location

with

good

electrical

contact

may

be

used.

(remove

paint).

system

vehicle.

a)

Negative

or

other

con-

venient

point,

and

connect

:

In

the

cases

of

tem,

connect

the

Black

radio

to

the

nega-

tive

terminal

or

other

convenient

point,

and

connect

2.

ANTENNA

This

radio

is

designed

to

operate

into

a

50

ohm

CITIZENS

RADIO

antenna.

Best

result

will

be

obtained

:from

your

transceiver

if

you

use

good

antenna

and

properly

install

your

antenna.

(Refer

to

the

antenna

installation

instructions

included

w~th

your

an-

tenna.)

A

vertically

polarized

quarter-wavelength

whip

antenna

provides

the

most

reliable

operation

and

greater

range.

The

shorter

loa-

ded-type

whip

antennas

are

more

attractive,

compact

and

adequate

for

applications

where

the

maximum

possible

distance

is

not

re-

quired.

Also,

the

loaded

whip

antennas

do

not

present

the

pro-

blems

of

height

imposed

by

the

full

quarter-wavelength

whip.

When

installed

in

a

boat,

the

transceiver

will

operate

most

efficiently

when

the

antenna

used

has

been

especially

designed

for

marine

applications.

Mobile

whip

antennas

utilize

the

metal

body

of

the

vehicle

as

a

ground

plane.

When

mounted

on

a

corner

of

the

vehicle,

they

are

slightly

directional,

in

the

direction

of

the

body

of

the

vehicle.

For

all

practical

purposes,

however,

the

radiation

pattern

is

non-

directional.

A

slight

directional

characteristic

will

be

observed

only

at

extreme

distances.

A

standard

antenna

connector

(Type

)

}

S0-239)

is

provided

on

the

transceiver

for

easy

connection

to

a

standard

PL-259

cable

termination.

Before

installing

the

transceiver

in

a

boat,

consult

your

dealer

f'or

information

regarding

an

adequate

grounding

system

and

pre-

vention

of'

electrolysis

between

fittings

in

the

hull

and

water.

3.

BASE

STATION

OPERATION

To

operate

the

transceiver

from

your

home

or

of'f'ice,

using

regu-

lar

house

current

as

the

power

source,

you

will

require

a

sepa-

rate

power

supply

capable

of'

supplying

5 amps

at

a 13.SV'DC

out-

put

with

a

nominal

input

voltage

of'

220

volts

AC,

50/60

Hz.

Simply

connect

the

red

(+}

and

black

(-}

leads

to

the

transceiver

to

the

corresponding

DC

terminals

of'

the

power

supply.

NOTE

Do

not

attempt

to

operate

this

transceiver

by

connecting

directly

to

220V

AC.

When

an

AC

power

supply

is

used

with

the

transceiver

for

base

station

operation

any

Citizens

Band beam,

dipole;·ground

plane

or

vertical·antenna

may

be

used.

A

ground

plane

vertical

antenna

will

provide

the·

most

uniform

horizontal

coverage.

4.

REMOTE

SPEAKER

The

external

speaker

jack

(EXT.

SPKR)

on

the

rear

panel

is

used

f'or

remote

receiver

monitoring.

The

external

speaker

should

have

8 ohms

impedance.

When

the

external

speaker

is

plugged

in,

the

internal

speaker

is

disconnected.

5.

PUBLIC

ADDRESS

An

external

8

ohm

4-watt

speaker

must

be

connected

to

the

(PA

SPKR)

jack

located

on

the

rear

panel

when

the

transceiver

is

used

as

a

public

address

system.

The

speaker

should

be

directed

away

from

the

microphone

to

prevent

accoustic

feedback.

Physical

se-

paration

or

isolation

of'

the

microphone

and

speaker

is

important

when

operating

the

PA

at

high

output

levels.

6.
