Epson Multimedia Projector Pro EX9220

The projector keeps track of the number of hours the lamp is used and displays this information in the projector's menu system.

Replace the lamp as soon as possible when the following occurs:

• The projected image gets darker or starts to deteriorate

• A message appears when you turn on the projector telling you to replace the lamp

• The projector's Lamp light is flashing orange and its power light is flashing blue

Before you replace the lamp, let the projector cool down for at least one hour so the lamp will not be hot.

Warning: Let the lamp fully cool before replacing it to avoid injury.

You can replace the lamp while the projector is mounted to the ceiling, if necessary.

Warning: Before cleaning any part of the projector, turn it off and unplug the power cord.

Warning: Never open any cover on the projector, except as specifically explained in this manual. Dangerous electrical voltages in the projector can injure you severely.

Warning: Do not try to service this product yourself, except as specifically explained in this manual. Refer all other servicing to qualified servicers.

Before cleaning the projector case, turn off the projector and unplug the power cord.

Did you use a soft, dry, lint-free cloth to remove dust or dirt?

Did you use a soft cloth moistened with water and mild soap to remove stubborn dirt?

Caution: Do not use wax, alcohol, benzine, paint thinner, or other chemicals to clean the projector case. These can damage the case.

Caution: Do not use canned air, or the gases may leave a flammable residue.

Warning: Do not use canned air. The gases may leave a flammable residue or push dust and debris into the projector's optics or other sensitive areas.

Turn off the projector and unplug the power cord.

Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as a paintbrush).

Note: You can remove the air filter so you can clean both sides of it. Do not rinse the air filter in water, or use any detergent or solvent to clean it.

If dust is difficult to remove or the air filter is damaged, replace the air filter.
