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.

1. RESISTORS:
Indicated In n , ¼W , Y .W ,:t. 5% tolerance unless otherwise noted k : kn ,
M : M n, (F) : :t. 1% . (G) : :t. 2% , (K) : t 10% IM) ; .t. 20% toleran ce
2. CAPACITORS:
Indicated in capacity (11Fl/voltage (VJ unless ~therwise noted p : pf
Indication without voltage is 50V except electrolytic capacitor.
3. VOLTAGE, CURRENT:
LJ : DC voltage IV) at no input signal
Value in ( I is DC voltage at rated power .
<:=, mA : DC current at no input signal
4. OTHER S:
.... : Signal route .
fl} : Adjusting point .
T he & mark found on some component parts ind~ates the im•
portance of the safety factor of the pan . The refore, when replacing,
be sure to use parts of I dentical designation.
* marked capacitors and resistors have parts numbers .
This is the basic schematic diagram, but the actual circuit may 11ary
due 10 impro11ements in design.
