L Laser Interlock Mechanism
The design prevents laaer diode 06cillation when Slide Switch
S2, for detect of Dioc: Ttny being put into tl'te pl ayer , ill not
ac tivated (IN SW si.Jnal : Hiih level.).
This Slide Switch S2 is activated by Rad: Gear (R) (ref er to
paa:e 8, No.3) when Disc Tray is put iaco t he pl ayer (IN SW
sign :11\ :Lowl~el).
Therefore, laserdiode oscillation will not
c.ontin ue without
Disc Tra y being placed in the player.
However, with Disc Trayout, th e interlock will no longer
function if Slide Switch S2 is manually activated.
2, When the cover is opened andthereinforced bridge (refer
to page 11 , No.1 01) i.s removed, cio.,e vie:win&' of the
ohjective lens with t
he naked eye will ca -.ee exposure to a
Class I Gr hi ther laser beam.
