state

of

the

product,

there

is

a

Replacement

of

@

Before

removing

the

pickup

assembly

be

sure

to

solder

-bridge

where

indicated

in

the

inset

(Fig.

4-1)

to

prevent

the

laser

diode

from

being

electrostatically

damaged.

After

replacing

the

pickup

assembly,

be

sure

to

unsolder

the

antistatic

bridge.

Or

else

the

laser

diode

does

not

function.

@

Before

servicing

the

pickup

assembly

be

sure

to

prevent

electrostatic-inducer

destruction

by

grounding

not

only

test

equipment

in

use

but

also

yourself

as

shown

in

Fig.

4-2.

*

Electrostatic

charge

drastically

shortens

the

operating

life

of

the

laser

diode

or

possibly

results

in

its

destruction.

@During

the

transportation,

mounting

and

dismounting

of

the

assembly,

support

with

your

fingers

at

points

A

and

B

as

shown

in

Fig.

4-3.

Be

particularly

careful

not

to

touch

the

actuator,

photosensor

and

LD

plate

and

do

not

apply

force

to

them.

@Don’t

touch

the

plated

portion

of

the

flat

cable

end

directly

with

fingers.

@Use

care

not

to

break

the

flat

@

Soldering

must

be

done

quickly

at

less

than

30W,
