are

neccessary.

To

as

shown

in

Maximum

output

and

frequency

response

can

be

obtained

only

when

the

record/playback

head

is

correctly

aligned

for

Azimuth.

Azimuth

alignment

refers

to

the

positioning

of

the

head

in

respect

to

the

tape

which

passes

across

it

during

recording

and

playback.

Since

the

head

adjustment

screw

is

set

and

sealed

at

the

factary,

adjustment

should

not

be

required

unless

the

screw

has

been

accidently

put

out

of

adjustment

in

some

manner.

If

a

record/playback

head

becomes

defective,

it

will

be

neccessary

to

align

the

new

head

for

correct

azimuth

after

installation.

To

do

so,

proceed

as

follows;

1.

Thread

a

pre-recorded

test

tape

(cassette

type)

(7,000

Hz

standard

frequency

tape)

onto

the

recorder.

2.

Connect

an

AC

voltmeter

across

the

speaker

voice

coil

termi-

nals.

To

make

this

connection

without

removing

the

recorder

from

the

cabinet,

connect

an

external

speaker

or

a

dummy

load

resistor

(same

impedance

as

that

of

the

speaker

voice

coil)

to

the

MONIT

EXT.

SP.

terminal.

NOTE:

Set

the

voltmeter

on

the

1.5

VAC

scale.

3.

Depress

the

PLAY

button

and

turn

the

tone

control

clockwise

until

a

reading

is

obtained

on

the

AC

voltmeter.

4.

Rotate

the

head

adjustment

screws

clockwise

or

counter-

clockwise,

and

continue

this

procedure

until

maximum

output

is

obtained

as

indicated

by

the

AC

voltmeter.

.

Head

demagnetization

Magnetization

of

the

heads

may

result

when

the

continuity

of

the

head

is

measured

with

an

ohmmeter.

If

it

is

neccessary

to

meas-

ure

head

continuity,

the

head

should

be

demagnetized

after

the

continuity

check.

Head

magnetization

is

evidenced

by

a

high

residual

noise

(a

hiss-

ing

and

low

popping

sound)

when

a

virgin

or

completely

erased

tape

is

played

at

a

high

volume

level.

The

magnetization

may

be

neutralized

by

use

of

a

standard

de-

magnetization

tool.

The

tip

of

the

tool

should

not

be

used

through

the

pad

but

must

be

thin

enough

to

fit

between

the

pres-

sure

pad

and

the

record/play

head.

A

piece

of

cellulose

tape

should

be

placed

over

the

end

of

the

tool

to

prevent

metal-to-

metal

contact

between

the

tool

and

the

head.

After

demagnet-

ization

is

completed,

slowly

remove

the

tool

from

the

vicinity

of

the

head

BEFORE

the

current

is

turned

off.
