NOTE

Interactive Function (continued)

• Do not place the projector near equipment that may emit

electromagnetic waves or radio waves, such as a radio transmitter, TV, copier,

or air-conditioner.

• Avoid excessively dusty places, or places that are subject to extremely high or

low temperature or humidity.

• The pen makes use of infrared light to detect positions. Avoid using it at a

place where the screen surface is directly exposed to sunlight. Also, note that

the pen may not function properly if it is used near an equipment that emits

infrared wavelengths (plasma display, motion sensor, or automatic lighting

sensor, etc.).

• The pen detects positions using ultrasonic waves, and therefore may not

function properly when used in an environment where resonance is likely to

occur, such as at the corner of a room or beside a metallic shelf.

• Malfunction may occur when two or more projectors are used in the same

room.

• The pen movement may be disrupted if the projector is used near an inverter

uorescent light, or when the light of an inverter uorescent light falls directly on

the screen.

• The PEN sensor may not work correctly if strong light (such as direct sunlight)

or light from an extremely close range (such as from an inverter uorescent

lamp) falls on the PEN sensor of the projector. Adjust the position of projector

avoiding those lights.

• When dust accumulates on the two horns of the pen sensor, the pen may

malfunction, or it may not function at all. When this occurs, check the horns of

the pen sensor, and remove any dust accumulated on them using a vacuum

cleaner.
