Solutions When the Interactive Touch Operation
Does Not Work
If the interactive touch operation using your finger does not work, try the
following solutions:
• Make sure the Touch Unit is installed correctly and the power cable is
properly connected. See your projector's
Installation Guide
for details.
• If the indicator on the Touch Unit is not on, check that
Touch Unit Setup
-
Power
is set to
On
in the projector's
Extended
menu.
• Adjust the angle on the Touch Unit. See your projector's
Installation Guide
for details.
• Make sure there are no obstacles (such as cables or pen trays) between the
Touch Unit's laser diffusion port and the projection surface. If there are any
obstacles that are difficult to move, attach the infrared deflectors to the
projection surface. See your projector's
Installation Guide
for details.
• Make sure there is no interference from infrared remote controls, mice, or
infrared microphones.
• If your finger position and the cursor position on the screen do not match,
perform
Touch Calibration

screen or any obstacles causing interference, the touch operations may not
work properly.
• If clothing, or any part of your body comes close to the screen, the touch
operations may not work properly. Move at least 1 cm away from the
screen.
• If touch operations do not work correctly even after performing calibration,
press the
icon on the Home screen to check the
Calibration Range
setting.
• If touch operations are mistakenly recognized as dragging operations,
select
Wide
.
• If mouse operations are not performed smoothly, select
Narrow
.
