When

instailing

the

transceiver

in

your

vehicle

consider

the

ease

of

operation

and

safety

when

selecting

the

location

for

the

mounting

bracket.

1.

instalt

the

2.

Attach

the

transceiver

loosely

using

the

4

screws

that

were

supplied.

3.

Align

the

grooves

in

the

bracket

with

the

transceivers

screws

(Fig.

and

slide

the

Installations

Cautions:

1.

Before

installing

the

power

cable

disconnect

the

nega-

tive

lead

from

the

battery

for

safety.

2.

After

installation

and

wiring

have

been

completed

go

back

and

check

your

work

to

ensure

that

you

have

not

made

any

errors,

before

you

reconnect

the

negative

bat-

tery

lead.

3.

if

the

fuse

opens

be

sure

to

check

that

each

conductor

is

undamaged,

then

replace

the

fuse

with

one

of

the

same

rating.

4.

After

completing

the

wiring,

wrap

the

fuse

holder

with

heat

resistant

tape

to

protect

against

heat

and

moisture.

5.

Do

not

remove

the

fuse

even

if

the

power

cable

is

too

long.

Pay

close

at-

to

the

polarity

of

the

when

connecting

them

to

the

Ignition

Noise

This

transceiver

has

been

designed

to

suppress

ignition

noise,

however,

you

may

occasionally

encounter

an

instal-

lation

where

the

use

of

suppressor

type

plugs

might

be

called

for.

Fixed

Station

A

regulated

DC

power

Supply

(13.8

VDC)

capable

of

sup-

plying

at

least

7

Amperes

is

required.

The

PS-430

or

the

PS-50

are

recommended.

CAUTION:

ote

1,

Never

connect

the

AC

power

cable

of

the

power

supply

to

the

AC

outlet

until

all

other

connections

have

been

made.

2.

Before

connecting

and

disconnecting

the

power

connec-

tor

be

sure

to

turn

OFF

the

POWER

switch

on

the

front

penel

of

the

transceiver

and

the

power

supply.

3.

Observe

proper

polarities

when

connecting

the

OC

power

cable

to

the

supply.

Remember

red

is

positive

and

biack

is

negative.

3-2-3.

Antenna

The

type

of

antenna

that

is

used

will

greatly

affect

the

per-

formence

of

the

transceiver.

Use

a

properly

adjusted

anten-

na,

of

good

quality,

to

enable

your

transceiver

to

perform

at

its

best.

The

antenna

input

impedance

is

50

ohms.

Use

60

ohm

coaxial

cable

such

as

RG-8U

or

8D-2V

for

this

con-

nection.

If

the

antenna

is

far

from

the

transceiver

the

use

of

low

loss

cable

is

recommended.

Match

the

impedance

of

the

coaxial

cable

and

that

of

the

antenna

so

that

the

SWR

will

be

less

than

1.5

to

1.

The

protection

circuit

in

the

tran-

sceiver

will

activate

if

the

SWR

is

particularly

poor

(greater

than

3

to

1).

High

SWR

values

will

cause

the

transmitter

output

to

fail

off

and

may

lead

to

TVI

or

BCI

reports.

CAUTION:

ee

teeta

bone

eee

We

recommend

that

you

instail

a

high

quality

lightening

ar-

restor

in

your

antenna

lines

for

protection

against

fire,

elec-

tric

shock,

personal

injury,

or

damage
