4-955-832-01: HTC-D259
4-955-832-11: HTC-D359 The transit key (a)) on the bottom exterior of the CD player protects
the optical system against shock during transportation.
Before operating the unit, be sure to remove the key by following the
instructions on the label, and store it in a safe place.
UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may
suffer electrostatic breakdown because of the poten-
tial difference generated by the charged electrostatic
load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-
down and also use the procedure in the printed
matter which is included in the repair parts.
The flexible board is easily damaged and should be
handled with care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so
as to be focused on the disc reflective surface by the
objective lens in the optical pick-up block. There-
fore, when checking the laser diode emission, observe
more than 30 cm away from the objective lens.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK A OR DOTTED
LINE WITH MARK A ON THE SCHEMATIC DIAGRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUB-
LISHED BY SONY.
When transporting the unit, put the key to its original position and
lock it in place.

Precautions:
1. Clean the following parts with a denatured-alcoholmois-
tened swab;
record/playback/erase head
pinch roller rubber belts
capstan idler
2. Demagnetize the record/playback head with a head demag-
netizer.
(Head demagnetizer do not approach for the erase head.)
3. Do not use a magnetized screwdriver for the adjustments.
4. After the adjustments, apply suitable locking compound to
the parts adjusted.
3. The adjustments should be performed in the rated power

1. Demagnetize the record “playback head with a head
demagnetizer. (Do not bring the head demagnetizer close
to the erase head.)
Do not use a magnetized screwdriver for the adjustments,
After the adjustments, apply suitable locking compound
to the parts adjusted.
4, The adjustments should be performed with the rated
power supply voltage unless otherwise noted,
5. The adjustments should be performed in the order given
in this service manual, (As a general rule, playback
circuit adjustment should be completed before performing
recording circuit adjustment.)
6. The adjustments should be performed for both L-CH and
R-CH,
