REPLACING OPTICAL PICK-UP
Handling
1) A red laser diode for Super Audio CD Player requires more
attention to static electricity than general infrared laser diodes
for CD.
Because its durability to static electricity is far weaker than
that of infrared laser diodes, always use an earth band when
handling the optical pick-up block as service parts.
2) As for the flexible board KHS-180A (RP) packed as service
parts, the short lands have been soldered to protect from static
electricity. Accordingly, remove solders when replacing opti-
cal pick-up. (See Fig. 1)
