Interactive Function (continued)
Preliminary preparation
To use the Interactive Function, a special pen is needed (8).
Insert battery into the pen before using (23).
The optional part Finger Touch Unit (FT-01B) enables Interactive operation by
fingers.
Using the pen
To write or draw using the pen, press the tip of the pen against the screen surface
and move the pen accordingly. Writing ends once the tip of the pen is moved
away from the screen surface.
Pay attention to the two points below when using the pen.
(1) When drawing using the pen, hold it perpendicularly to the screen as much as
possible, and draw objects by pressing the tip of the pen against the screen to
apply writing pressure.
(2) If the characters or objects that you have written or drawn on the screen
cannot be loaded correctly on the computer, check whether the problem can be
resolved by changing the way you hold the pen.
CAUTION
• Do not expose the pen to water or other fluids. If the pen is wet accidentally,
wipe it dry immediately.
• If you do not intend to use the pen for a long time, remove the battery.
NOTE
• The projector detects the pen coordinates by reading infrared emitted
by the pen. Therefore, input may fail if transmission between the pen and the
projector is blocked. Make sure that signal transmission is not obstructed.
►Do not drop the pen or mishandle it.
