Interactive Function (continued)
Preliminary preparation
Using the pen
To use the Interactive Function, a special pen is needed (6).
Insert battery into the pen before using (20).
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. When information is sent out correctly from the pen,
a faint operating sound can be heard. Be aware that this is not a failure or
malfunction.
(2) The tip of the pens comes with a mini built-in transmitter. Transmission of
drawing data from the pen may fail if you hold the pen at the transmission
unit while writing or drawing. 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.
►Do not drop the pen or mishandle it.
• Do not expose the pen to water or other uids. 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.
• When using the pen, do not hold it at the black line or any area beyond it.
Otherwise, the pen may not function properly.
CAUTION
NOTE
• The projector detects the pen coordinates by reading infrared and
ultrasound signals 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.
