performance,

please

read

this

manual

carefully.

Keep

it

in

a

safe

place

for

future

reference.

Install

this

unit

in

a

cool,

dry,

clean

place

--

away

from

windows,

heat

sources,

sources

of

excessive

vibration,

dust,

moisture

and

cold.

Avoid

sources

of

humming

(transformers,

motors).

To

|

prevent

fire

or

electrical

shock,

do

not

expose

the

unit

to

rain

or

water.

|

Never

open

the

If

something

drops

into

the

Do

not

use

force

on

the

wires

connected

to

other

equipment.

Never

pull

the

wire

itself.

The

openings

on

the

cabinet

assure

proper

ventilation

of

the

amplifier.

If

these

openings

are

obstructed,

the

temperature

inside

the

cabinet

will

rise

rapidly

and

eventually

damage

the

Circuits.

Therefore,

avoid

placing

objects

against

these

openings

and

do

not

install

the

amplifier

where

the

flow

of

air

through

the

ventilation

openings

could

be

impeded.

Always

set

the
