OPTICAL PICK-UP BLOCK TYPE DISCRIMINATION
There are two types of the optical pick-up block in this model.
These are compatible except for the laser power.
Check the type of the optical pick-up block before replacement.
Ajdust following items after replacing the optical pick-up block.
• 5-6-2. Laser Power Check (See page 26)
• 5-10. LASER POWER ADJUSTMENT (See page 29)

• CLEANING THE OPTICAL PICK-UP
Note 1:
In cleaning the lens, do not apply an excessive force
As the optical pick-up is vulnerable, application of
excessive force could damage the lens holder.
Note 2:
In cleaning, do not use a cleaner other than exclusive
cleaning liquid. (KK-91 or isopropyl alcohol)
Note 3:
Wipe the obujective lens spirally from center toward
outside. (See Figure A)
Note 4:
Eject the disc, if loaded.
Note 5:
Disconnect the power cord from the socket to shut off
the power supply.
