of

each

band

on

the

display

(not

available

in

the

GEQ

mode).

Diffuse

Function

This

applies

a

the

follow-

ing:

Power

Supply

*

Before

connecting

this

unit

to

other

devices,

turn

off

the

power

to

all

units;

this

will

help

prevent

damage

or

mal-

function.

*

Do

not

use

this

unit

on

the

same

power

circuit

with

any

device

that

will

generate

line

noise;

an

electric

motor

or

variable

lighting

system

for

example.

Placement

*

Using

the

unit

near

power

amplifiers

(or

other

equipment

containing

large

power

transformers)

may

induce

hum.

*

This

device

may

interfere

with

radio

and

television

recep-

tion.

Do

not

use

this

device

in

the

vicinity

of

such

receivers.

Maintenance

¢

For

everyday

cleaning

wipe

the

unit

with

a

soft,

dry

cloth

or

one

that

has

been

slightly

dampened

with

water.

To

remove

stubborn

dirt,

use

a

mild,

non-abrasive

detergent.

Afterwards,

be

sure

to

wipe

the

unit

thoroughly

with

a

soft,

dry

cloth.

¢

Never

use

benzene,

thinners,

alcohol

or

solvents

of

any

kind,

to

avoid

the

possibility

of

discoloration

and/or

defor-

mation.

Additional

Precautions

*

Protect

the

unit

from

strong

impact.

¢

A

small

amount

of

heat

will

radiate

from

the

unit

during

normal

operation.

¢

Before

using

the

unit

in

a

foreign

country,

consult

with

qual-

ified

service

personnel.

Memory

Backup

*

This

unit

contains

a

battery

which

powers

the

unit’s

memory

circuits

while

the

main

(AC)

power

is

off.

The

expected

life

of

this

battery

is

3

years

or

more.

However,

to

avoid

the

untimely

loss

of

memory

data,

it

is

strongly

recommended

that

you

change

the

battery

every

3

years.

Please

be

aware

that

the

actual

life

of

the

battery

will

depend

upon

the

phys-

ical

environment

—

especially

the

temperature

—

in

which

the

unit

is

used.

When

it

is

time

to

change

the

battery,

con-

sult

with

qualified

service

personnel.

When

the

battery

becomes

weak

the

following

message

will

appear

in

the

display:

"Battery

Low

Please

Change."

Please

change

the

battery

as

soon

as

possible

to

avoid

the

loss

of

memory

data.

Please

be

aware

that

the

contents

of

memory

may

at

times

be

lost;

when

the

unit

is

sent

for

repairs

or

when

by

some

chance

a

malfunction

has

occurred.

Important

data

should

be

stored

in

another

MIDI

device

(eg.,

a

sequencer),

or

writ-

ten

down

on

paper

(if

possible).

During

repairs,

due

care

is

taken

to

avoid

the

loss

of

data.

However,

in

certain

cases

(such

as

when

circuitry

memory

itself

is

out

of

order),

we

regret

that

it

may

not

be

possible

to

restore

the

data.

The

AP-700

is

equipped

with

the

following

three

modes.

Select

the

mode

according

to

what

you

wish

to

do.

See

"Choosing

the

Mode"

(p.

10)

if

you

need

more

information

on

how

to

select

a

mode.

all

the

way,

and

that

all

equip-

ment

is

switched

make

the

connection

through

a
