JProcedure of lamp unit replacement
Attention
When the projector is mounted in the ceiling, do not work directly under\
 the projector or put your face close to the projector.
 
z
The lamp unit and the lamp unit cover must be attached correctly and sec\
urely. Failure to do so, the projector will not be 
 
z
turned on for the protection circuit.
If the lamp unit is not installed smoothly, remove it and then install it again. If it is pushed in forcibly, its connector may be 
 
z
broken.
Turn the main power OFF, following the 
1  ) 
procedures described in “Powering off 
the projector” (
Æpage 40), disconnect 
the power plug from the AC power 
source, and wait for one hour or more. 
Then check that the lamp unit has 
cooled down. 
Turn the “lamp unit cover fixing 
2  ) 
screw” (1 piece) with a Phillips-head 
screwdriver until it is fully loosened, 
and then hold the “lamp unit cover” 
securely and open it in the direction of 
the arrow.
Use a Phillips screwdriver to loosen 
3  ) 
the “Lamp unit cover fixing screw” (4 
screws) for the lamp unit to be replaced 
until the screws turn freely. Hold the 
“Handle” of the “Lamp unit” and 
gently pull the lamp unit out from the 
projector.
Replace the new LAMP unit in correct 
4  ) 
direction.
Use a Phillips screwdriver to securely 
5  ) 
tighten the 2 “Lamp unit cover fixing 
screw” for each lamp unit.
Close the “lamp unit cover” and 
6  ) 
tighten the “lamp unit cover fixing 
screw” (1 piece) securely with a 
Phillips-head screwdriver in the 
reverse order to Step 2).
Note
When the lamp unit is replaced, the duration of usage 
 
z
time will be reset to “0”.
