Safety Instructions for Interactive Features
The interactive feature operates by infrared communication. Note the
following important points when using this feature.
• Make sure there is no strong light or sunlight shining on the interactive pen
receiver and the projection screen.
• If there is any dust stuck to the interactive pen receiver, it could interfere
with infrared communication and you may not be able to use the features
normally. Clean the receiver if it is dirty.
• Do not put paint or any stickers on the cover of the interactive pen receiver.
• Do not use an infrared remote control or infrared microphone in the same
room because the interactive pen may malfunction.
• Do not use devices that generate powerful noise, such as rotary devices or
transformers, near the projector. You may not be able to operate the
interactive features.

color on the end of the pen. You can use either pen, or both at the same time
(one of each color).
