INSTALLATION

LOCATION

|

Install

the

amplifier

in

a

well

ventilated

location

where

it

will

not

be

exposed

to

high

temperature

or

humidity.

Do

not

install

the

amplifier

in

a

location

which

is

exposed

to

direct

rays

of

the

sun,

or

near

hot

appliances

or

radiators.

Excessive

heat

can

adversely

affect

the

cabinet

and

internal

components.

Installation

of

the

amplifier

in

a

damp

or

dusty

environment

may

result

in

malfunction

or

accident.

(Also

avoid

installation

near

cookers

etc.,

where

the

amplifier

may

be

exposed

to

smoke

from

oil,

steam

or

heat.)

POWER-CORD

CAUTION

Handle

the

power

cord

by

the

plug.

Do

not

pull

out

the

plug

by

tugging

the

cord

and

never

touch

the

power

cord

when

your

hands

are

wet

as

this

could

cause

a

short

circuit

or

electric

shock.

Do

not

place

the

unit,

a

piece

of

furniture,

etc,.

on

the

power

cord,

or

pinch

the

cord.

Never

make

a

knot

in

the

cord

or

tie

it

with

other

cords.

The

power

cords

should

be

routed

such

that

they

are

not

likely

to

be

stepped

on.

A

damaged

power

cord

can

cause

fire

or

give

you

an

electrical

shock.

Check

the

power

cord

once

in

a

while.

When

you

find

it

damaged,

ask

your

nearest

PIONEER

authorized

service

center

or

your

dealer

for

a

replacement.
