Additional Laser Caution
1.
Laser Interlock Mechanism
The
design prevents laser diode oscillation when Slide Switch
S2
, for detect of Disc
Tray
being put into the player, is not
activated (IN SW signal : High level).
This Slide Switch
S2
is activated by Rack Gear
(R)
(refer to
page
8,
No
.
3)
when Disc
Tray
is put into the player (IN
SW
signal : Low level).
Therefore,
la
ser diode oscillation will not continue without
Disc
Tray
being placed in the player.
However, with Disc
Tray
out, the interlock will no longer
function
if
Slide Switch S2 is manually activated.
2.
When the cover is opened and the reinforced bridge (refer
to page 11, No.101)
is
removed, close viewing of the
objective lens with the naked eye will cause exposure to a
Class 1 or higher laser beam.
