SERVICING NOTES

Laser Diode Properltes

' Material: GaAlAs

0 Wavelength: 780 nm

0 Emission Duration: continuous

' Laser Output Power: less than 44.6 pW*

* This output is the value measured at a distance of 200

mm from the objective lens surface on the Optical Pick~
up Block.

CAUTION

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

NOTES ON HANDLING THE OPTICAL
PICK-UP BLOCK 0R BASE UNIT

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

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

- 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 solder-
ing 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
