3. Voltage selector (rear panel)

·Worldwide models

are

equipped

with a voltage selector to conform with local power supplies.

Be

sure to set this

switch to match the voltage

of

the power supply in your

area

before turning the

power

switch

on

. Voltage

is

changed by sliding the groove in the switch with a screwdriver to the right

or

left. Confirm

that

the switch has

been moved all the way to the right

or

left before turni~g

the

power

switch

on.

Models without a voltage selector

can only be used

in

areas where the

power

supply

is

the same as

that

of

the unit.

ADJUSTMENT

PROCEDURES

Adjustments and Checking the Protection Circuitry

I.

Preparations

I)

Place

the

unit

on

the

workbench.

(There

should

be

about

15

mm

of

space

between

the

base

plate

of

the

unit

and

the

work

surface.)

2) Set up

the

unit as follows.

(I)

No load

(2) No signal

(3)

Volume

turned

all

the

way

down

(4)

Speaker

switch

OFF

(5)

Power

switch

OFF

Note)

Check

the

following points

before

making

adjustments

(I)

The

power

switch

should

be

OFF.

(2)

The

interior

of

the

unit should

not

be

warm

.

2. Idling current adjustment

1)

Turn

the

power

switch

ON

and

allow

the

unit

to

warm up for

about

10

minutes.

(1) Adjust R535 (R635) so

that

the

voltage at test point

VCT-IID

on

the

NAAF-3601 circuit

board

is

15mV

±Sm

V.

Note)

Semi-fixed resistors enclosed in

par

entheses ( )

are

for

the

right channel.

3. Check

of

operation

of

protection circuitry

I)

Check

of

operation

of

protection

relay

(I)

Confirm

that

the

relay turns

ON

approximately

5 seconds

after

the

power

switch

is

turned

ON

.

(2)

The

SERVO

indicator

LED

should

light

at

the

same

time.

(3)

The

relay

should

turn

OFF

approximately

0.5 seconds

after

the

power

switch

is

turned

OFF

.

2)

Check

of

DC

detection

and

servo circuitry

operation

(1)

Turn

the

power

on

with no load.

(2)

After

the

speaker

relay

turns

ON,

apply

DC+

200mV

to

the

CD

input terminals.

Confirm

that

the

relay turns

OFF

.

(3) Confirm

that

operation

is

the

same

as (2)

above

when an

input

of

DC-200mV

is

applied.

Note)

Under

no circumstances

connect

a load

or

short

the

speaker

terminals when

performing

the above test.

3) Signal input from

the

circuit illustrated below with

no

load.

(I)

Confirm

that

the

speaker

relay

does

not

turn

OFF

even when a 2

ohm

load

is

connected

when a p

ea

k value

of

35V

p-p

is

output.

(2)

Next,

confirm

that

when a 1

ohm

load

is

connected

the

speaker

relay switchse

OFF

and

ON

a couple

of

times

and

then

stays

OFF.

Note)

The

period

before

that

relay stays

OFF

should

not

last for

more

than

1 minute.

Relay

OFF

status can be

canceled

by switching the

power

OFF.
