• Prior to performing the following procedure, remove the top
cover.
• There is no need to remove the front panel assembly.
(1) Insert a kind of screwdriver in a hole located in the right
side of mechanism assembly, and push a lever until it can-
not be inserted any further. (See Figure 2)
(2) And then, a tray will come out. Remove the tray in an upper
direction, with slightly opening the lower part of fitting in an
outward direction. (See Figure 2)
(3) Remove the three screws D attaching the mechanism as-
sembly.
(4) The switch on a relay board is made into the "SHORT" side.
(5) Disconnect the card wire from connector
servo control and signal output terminal board.
(6) Remove the mechanism assembly by lifting the rear part of
the mechanism assembly.
ATTENTION:
Please be sure to make the switch on a relay board into a
"SHORT" side before disconnect a card wire from the connec-
tor CN101 on servo control and signal output terminal board.
Moreover, please be sure to make a switch into the "OPEN"
side after inserting a card wire in a connector
time of an assembly.
There is a possiblity of destroying the laser diode of a pick-up
unit with static electricity.
