CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of soldering iron around 270˚C

during repairing.

• Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering

or unsoldering.

Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.

Precaution

1. Clean the following parts with a denatured alcohol-moistened
swab:
record/playback head pinch rollers
erase head rubber belts
capstan idlers

2. Demagnetize the record/playback head with a head
demagnetizer.

3. Do not use a magnetized screwdriver for the adjustments.

4. After the adjustments, apply suitable locking compound to the
parts adjusted.

5. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.

NOTE:

• Due to standardization, replacements in the
parts list may be different from the parts
specified in the diagrams or the components
used on the set.

• -XX, -X mean standardized parts, so they
may have some difference from the original
one.

• Items marked “*” are not stocked since they
are seldom required for routine service.
Some delay should be anticipated when
