How to open the tray when the power cannot be turned on
When the tray cannot be opened because the power cannot be
turned on, it can be opened using the emergency disc ejection
rod (GGF1529). (A long, thin rod about 1 mm in diameter can be
used in place of the rod.)
Insert the rod through the slit at the bottom of the unit and slide
the projection for cam R9 in the direction of the arrow, using the
rod. When the tray is popped out a little, pull it out by hand. Find
the projection by inserting the rod through the slit by about 20
mm, as the projection is not visible from the outside. If the
insertion of the rod exceeds 20 mm, you cannot catch the
projection.
