1.2 PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in PIONEER set have special
safety related characteristics. These are often not evident from
visual inspection nor the protection afforded by them necessarily
can be obtained by using replacement components rated for higher
voltage, wattage, etc. Replacement parts which have these special
safety characteristics are identified in this Service Manual.
Electrical components having such features are identified by marking
with a
on the schematics and on the parts list in this Service
Manual.
The use of a substitute replacement component which dose not have
the same safety characteristics as the PIONEER recommended
replacement one, shown in the parts list in this Service Manual,
may create shock, fire, or other hazards.
Product Safety is continuously under review and new instructions
are issued from time to time. For the latest information, always
consult the current PIONEER Service Manual. A subscription to,
or additional copies of, PIONEER Service Manual may be obtained
at a nominal charge from PIONEER.
1.3 REPLACING THE LAMP
The system sets the interlock switch to OFF when the cover is
removed. For safety reasons, the power cannot be turned ON.
Be sure to disconnect the power plug when replacing the lamp.
The projector will still be very hot inside just after the power is
turned off.
Therefore, wait more than one hour after turning off the power
and check that the projector has cooled down inside before
replacing the lamp.
Replacing the lamp while the projector is being used or
immediately after it has been stopped will cause burns because
the lamp is still very hot.

Never touch the light bulb or the reflecting mirror with your bare
hands. Dirt left behind from fingerprints or from your hands could
cause the lamp to overheat, and this in turn could shorten the
effective life of the lamp.
Be sure to read the instruction manual provided with your Liquid
crystal projector before replacing the lamp. (Also be sure to reset
to the lamp life meter after replacing the lamp.)
Push down the handle in the direction shown.

1.4 CAUTION: HIGH TEMPERATURE
The mirror case and lamp assembly of this system become hot during
operation. Before servicing, turn the power off and wait until the
system cools down.
1.5 CHARGED SECTION
Charged section
The circuit in which the commercial AC power is used as it is without
passing through the power supply transformer. If the charged section
is touched, there is a risk of electric shock. In addition, the measuring
equipment can be damaged if it is connected to the GND of the
charged section and the GND of the non-charged section while
connecting the set directly to the commercial AC power supply. In
this case, be sure to connect the set via an insulated transformer and
supply the current.
Charged section (Power supply primary side)
1. AC FILTER Assy
2. The primary side of the DC POWER SUPPLY Assy
3. AC INLET
4. Power Switch (S2303)
5. AC Power Cord
6. Interlock Switch (S2301)
7. Thermostat (S2302)
