In

Case

of

Moving

the

Unit

Before

moving

the

unit,

be

sure

to

pull

out

the

power

cord

from

the

AC

outlet

and

disconnect

the

interconnection

cords

with

other

units.

Cleaning

If

the

unit

gets

dirty,

wipe

it

with

a

soft

dry

cloth.

If

necessary,

wipe

it

with

a

soft

cloth

dampened

with

mild

soapy

water

and

then

with

a

dry

cloth.

Never

use

benzene,

thinner,

alcohol

or

other

volatile

agent,

and

avoid

spraying

an

insecticide

near

the

unit.

Protection

Circuit

The

protect

light

indicates

that

the

protection

circuitry

of

your

amplifier

is

engaged.

The

light

will

come

on

under

two

circumstances:

•

When

you

turn

the

unit

on.

As

the

unit

prepares

itself

for

operation,

a

muting

circuit

temporarily

prevents

pops

or

other

noise

from

reaching

your

speakers.

When

the

unit

is

ready

for

operation

(in

approximately

10

seconds),

the

light

will

go

off.

•

When

the

unit

detects

a

problem.

This

light

will

come

on

if

your

speakers

wires

are

touching,

causing

a

short

circuit,

or

if

your

amplifier

overheats.

In

the

case

of

overheating,

a

thermal

sensor

will

shut

down

the

unit

before

damage

can

occur.

Depending

on

the

cause

and

extent

of

the

overheating,

the

unit

may

take

some

time

to

cool

down,

and

the

protection

circuit

will

remain

in

operation

until

the

unit

is

cool

enough

to

operate

safely.

In

the

case

of

a

short

circuit

in

the

speaker

wires,

the

protection

circuitry

will

attempt

to

reset

itself

every

10

seconds,

and

you

may

hear

a

slight

click

as

it

does

so.

The

protection

circuit

will

remain

in

operation

until

the

condition

is

corrected.
