Protection equipment for lamp replacement :
The Lamp circuit (the lamp and the electrode of the lamp socket) of this projector is not
insulated from AC line, and it is "HOT." Therefore, when replacing lamp assembly, an
electric shock may be received. However, the interlock switch (SW902) is designed so that
it may protect from the accident.
■
This switch(SW902) insulates a lamp circuit from AC line, when lamp cover is removed.
(The lamp circuit changes to "COLD.")
■
The note for service-personnel :
Push in and hold the lever of the interlock switch when the projector turns on by state of
no cabinet.
