Air filter

• Be careful not to suck in the air filter

itself.

• The air filter must be fitted in place when using the projector.

Using the projector without the air filter fitted inside, dirt and dust are sucked into the projector,

causing failure.

Attention

• If cleaning cannot remove the dust completely, then it is a sign to replace the air filter. Consult the

dealer. In addition, when the lamp unit is replaced, also replace the air filter.

Note

If too much dust is deposited in the air filter, temperature inside the main unit will rise and the temperature monitor

(TEMP) lamp blinks, eventually turning off the power supply.

Clean the air filter section once every 100 hours or so as a guideline depending on the location of projector

operation.
