0 Keep the temperature of the soldering iron around
270°C during repairing.

0 Do not touch the soldering iron on the same conductor
of the circuit board (within 3 times).

0 Be careful not to apply force on the conductor when
soldering or unsoldering.

Notes on chlp component replacement

0 Never reuse a disconnected chip component.
0 Notice that the minus side of a tantalum capacitor may
be damaged by heat,

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT

The laser diode in the optical pick»up block may suffer
electrostatic breakdown because of the potential difference
generated by the charged electrostatic load, etc. on clothing
and the human body.

During repair, pay attention to electrostatic breakdown 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

CAUTION

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

DISC MAGAZINE GEITING OUT PROCEDURE
ON THE POWER SUPPLY IS OFF

Remove the CASE (UP) assembly beforehand

1) Press the arm (M lock) assy to arrow direction.
2) Removal the magazine assy.

Note: Take out the magazine only when the tray is
