1)

A red laser diode for DVD 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)

The optical pick-up of the DVP-F5/FX1 cannot be replaced as
a single part.  It is supplied as the MD COMPLE (DVDM-
FX1).

Note: When the MD COMPLE is going to be replaced, be very

careful not to damage the flexible board to peel off the
flexible board because the flexible board is attached
underneath the cabinet by the double-sided adhesive tape.

3)

When handling the MD COMPLE (DVDM-FX1), be careful
not to touch the portions specified in the illustration of the MD
COMPLE with hand.  Be sure to hold the hatched portions
described as “HOLD” in the illustration.

For any attempt is going to be made to inspect, check and adjust
the MB-90 board, connect the DM flexible extension board as
shown below.
