DT01121 lamp replacement and time  

• If the DT01121 lamp should break (it will make a loud bang when it does), unplug

the power cord from the outlet, and make sure to request a replacement

lamp from your local dealer. Note that shards of glass could damage the

projector’s internals, or cause injury during handling, so please do not try to

clean the projector or replace the lamp yourself.

• If the lamp should break (it will make a loud bang when it does), ventilate

the room well, and make sure not to breathe the gas that comes out of the

projector vents, or get it in your eyes or mouth.

• Before replacing the DT01121 lamp, make sure the power switch is off and the

power cable is not plugged in, then wait at least 45 minutes for the lamp to

cool sufficiently. Handling the lamp while hot can cause burns, as well as

damaging the lamp.

• Do not open the DT01121  lamp cover while the projector is suspended from above.

This is dangerous, since if the lamp’s bulb has broken, the shards will

fall out when the cover is opened. In addition, working in high places is

dangerous, so ask your local dealer to have the lamp replaced even if the

bulb is not broken.

• Do not use the projector with the lamp cover removed. At the lamp

replacing, make sure that the screws are screwed in firmly. Loose screws

could result in damage or injury.

on a ceiling, or if the lamp has broken, also ask 

the dealer to replace the lamp.
