*1 Using infrared and compact cameras, this product captures the image (shadow) of a pen or finger
and detects the corresponding coordinate position. Do not operate near lighting that will obstruct the
capture of the image. This includes:
・ Locations where direct sunlight strikes the board surface or comes from the side.
・ Locations with white incandescent lighting or strong infrared source directly overhead.
Depending on installation conditions or sensor property, position detection may be off by about
9 mm.
*2 The electronic pen uses infrared light having the same frequency (approx. 940 nm).
Do not operate this product in a location where other equipment (fluorescent lighting, plasma
displays, passive sensors, etc.) may emit a similar frequency.
*3 The expected battery lifetime may vary depending on initial battery conditions, humidity, and the
operating environment.
