Maintenance

1.

Press the POWER button to switch off the 
projector.  Disconnect the power cord from 
the outlet and the projector. 

2.

Loosen the screw and remove the lamp 
cover. If the lamp is hot, avoid burns by 
waiting 45 minutes until the lamp has cooled. 

3.

Loosen the 3 screws. (It is strongly 
recommended you use a magnetic-headed 
screwdriver.) Pull the handle to remove the lamp 
housing. If the screws are not loosened completely, 
they could injure your fingers. Do not insert your 
hand into the box after the lamp is removed. If you 
touch the optical parts inside, this could cause 
color unevenness. 

4.

Replace the lamp with a new one. Insert it into 
the projector, and tighten the screws firmly. 
Loose screws may cause a bad connection, which 
may result in malfunction. 

5.

Re-install the lamp cover and tighten the screw. 
Do not turn on the power with the lamp 
cover removed. Whenever the lamp is 
replaced, reset the total lamp operation time. Do 
not reset if the lamp is not replaced as this 
could cause breakage.
