2.2.3 Installation precautions
a) Installation of multiple systems
Since the dedicated handwriting pen of the system is designed to function as a switch by emitting ultrasound waves,
mutual interference may occur when more than one system is installed in proximity (the interference may also be
observed even when the areas are separated with a simple tool such as partitions). In this case, it is required to use the
systems in NORMAL mode.
Some of the installation examples in which mutual interference is expected are shown below.
¶ Adjacent installation
¶ Adjacent booths delimited with simple partitions
¶ Back-to-back installation across a simple partition
b) Exposure to direct sunlight
Normal lighting is not a problem, but installation in a location exposed to strong lighting and intense direct sunlight will
make the plasma display difficult to view and make toucth screen device operation unstable. Installation in such a
location will also make remote control operation erratic.
Note that whereas normal fluorescent lighting does not emit infrared radiation, incandescent lamps emit a large amount
of infrared radiation. When the system malfunctions due to the presence of strong lighting, move the light source away
or change its orientation to prevent malfunction. Also, when equipment generating IR rays (electric stove, IR LAN, etc.)
is located near the handwriting device, its operation is usually normal but may sometimes be rendered unstable under
certain installation conditions. This needs to be checked in individual installations.
c) Ultrasonic waves
When equipment using ultrasonic waves (ultrasonic humidifier, ultrasonic-sensor door, ultrasonic eyeglass cleaner, etc.)
is used near the handwriting device, its operation is usually normal but may be rendered unstable under certain
installation conditions. This needs to be checked in individual installations.
