Notes on chip component replacement

• Never reuse a disconnected chip component.

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

aged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C dur-

ing 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.

NOTES ON HANDLING THE OPTICAL PICK-UP

BLOCK OR BASE UNIT

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED

LINE WITH MARK 0 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.

CAUTION

Use of controls or adjustments or performance of procedures

other than those specified herein may result in hazardous ra-

diation exposure.

The laser diode in the optical pick-up block may suffer electro-

static break-down because of the potential 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

Never look into the laser diode emission from right avove when

checking it for adustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK

(KMS-241C/J1NP).

The laser diode in the optical pick-up block may suffer electro-

static break-down easily. When handling it, perform soldering

bridge to the laser-tap on the flexible board. Also perform m easures

against electrostatic break-down sufficiently before the operation.

The flexible board is easily damaged and should be handled with

care.

seconds to turn off the clock display after

turning off the engine.

When you press (OFF) only momentarily,

the clock display does not turn off and this

causes battery wear.
