Air Filter and Vent Maintenance

Is there a message telling you to clean or replace the air filter?

Is the air filter torn or damaged?

Turn off the projector and unplug the power cord.

Slide the air filter cover latch and open the air filter cover.

Pull the air filter out of the projector.

Dispose of used air filters according to local regulations.

Place the new air filter in the projector as shown and push gently until it clicks into place.

Warning: Do not use a lens cleaner that contains flammable gas to clean the obstacle sensor. The high heat generated by the projector lamp may cause a fire.

Attention: Do not use glass cleaner or any harsh materials to clean the obstacle sensor and do not subject the obstacle sensor to any impacts. Damage on the surface of the sensor may cause malfunctions.

Replacing the Interactive Pen Tip

Two interactive pens come with two types of pen tips, soft tips and hard tips.

The soft pen tips are installed on the pens by default.

• If the soft tip gets dirty or damaged, it becomes less responsive. Replace it with a new one supplied with the product.

• If the soft tip is hard to use on a textured surface, replace it with the hard tip.

If the hard tip is worn down or damaged, replace it with a new one.

1. Twist off the tip of the interactive pen to remove it.

2. Pull the soft tip straight out.

Warning: Do not use a lens cleaner that contains flammable gas. The high heat generated by the projector lamp may cause a fire.

Attention: Do not use glass cleaner or any harsh materials to clean the projection window and do not subject the projection window to any impacts; otherwise, it could be damaged.

The projector monitors 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 quality declines

• A message is displayed when you turn on the projector telling you to replace the lamp (the message is displayed 100 hours before the expected end of the lamp life and appears for 30 seconds)

• The projector's power indicator is flashing blue and its lamp indicator is flashing orange.

• If you continue to use the lamp after the replacement period has passed, the possibility that the lamp may explode increases. When the lamp replacement message appears, replace the lamp with a new one as soon as possible, even if it is still working.

• Do not repeatedly turn off the power and then immediately turn it back on. Turning the power on and off frequently may shorten the lamp's operating life.
