case

of

trouble

|

When

the

unit

dose

not

operate

properly,

contact

your

dealer

or

the

nearest

authorized

PIONEER

Service

Station.

Never

remove

the

to

attempt

check

or

repairs.

Memory

Backup

When

the

car

battery

is

removed

or

power

cord

of

this

unit

is

disconnected,

and

the

power

is

not

supplied

for

about

3

days,

the

settings

of

the

position

and

equalizer

curves,

etc.

are

initialized.

Connecting

the

Units

Note:

*

This

unit

is

for

vehicles

with

a

12-volt

battery

and

negative

grounding.

Before

installing

it

in

a

recreational

vehicle,

truck,

or

bus,

check

the

battery

voltage.

*

To

avoid

shorts

in

the

electrical

system,

be

sure

to

disconnect

the

battery

©

cable

before

beginning

installation.

*

Refer

to

the

owner's

manual

for

details

on

connecting

the

power

amp

and

other

units,

then

make

connections

correctly.

«

Secure

the

wiring

with

cable

clamps

or

adhesive

tape.

To

protect

the

wiring,

wrap

adhesive

tape

around

them

where

they

lie

against

metal

parts.

«

Route

and

secure

all

wiring

so

it

cannot

touch

any

moving

parts,

such

as

the

gear

shift,

handbrake,

and

seat

rails.

Do

not

route

wiring

in

places

that

get

hot,

such

as

near

the

heater

outlet.

If

the

insulation

of

the

wiring

melts

or

gets

torn,

there

is

a

danger

of

the

wiring

short-circuiting

to

the

vehicle

body.

-

Don’t

pass

the

orange

lead

through

a

hole

into

the

engine

compartment

to

connect

to

the

battery.

This

will

damage

the

lead

insulation

and

cause

a

very

dangerous

short.

:

*

Donot

shorten

any

leads.

If

you

do,

the

protection

circuit

may

fail

to

work

when

it

should.

DEG-7200

Never

feed

power

to

other

equipment

by

cutting

the

insulation

of

the

power

supply

lead

of

the

unit

and

tapping

into

the

lead.

The

current

capacity

of

the

lead

will

be

exceeded,

causing

over

heating.

When

replacing

fuse,

be

sure

to

use

only

fuse

of

the

rating

prescribed

on

the

fuse

holder.

;

When
