Interactive Function (continued)
NOTE
• 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 movement may be disrupted if the projector is used near an inverter
fluorescent light, or when the light of an inverter fluorescent light falls directly on
the screen.
• The PEN sensor (Camera) may not work correctly if strong light (such as
direct sunlight) or light from an extremely close range (such as from an inverter
fluorescent lamp) falls on the PEN sensor (Camera) of the projector. Adjust the
position of projector avoiding those lights.
• Install and use at a position where the screen size is between 60"-100" when
digital zoom is at the maximum (100%) and the KEYSTONE and PERFECT FIT
functions are not used. If the KEYSTONE or PERFECT FIT function is used,
the position of the pen may not be reflected correctly on the screen, or pen
operation may not yield any response even on the 60''-100'' sized screen.
• StarBoard Software may not activate, if DirectX function of the computer is
®
turned off. In that case, turn on DirectX function. Please inquire your computer
®
or OS support hotline on how to confirm the settings of DirectX function On/
®
Off.
