Using Interactive Touch Operations with Your Finger
You can use your finger to interact with the projected screen, just as you
would use an interactive pen. You can use either a pen or your finger, or use
both at the same time.
The projector recognizes up to six touch points in computer interactive mode.
When performing touch operations with your finger, you can use two fingers
in annotation and whiteboard modes.
Do the following before using your finger for touch operations:
• Install the Touch Unit
• Calibrate the system manually for the pen
• Perform angle adjustment for the Touch Unit
• Calibrate the system for touch operations
See the Installation Guide for details.
The Touch Unit turns on and is ready for touch operation with your finger
when you turn on the projector and the indicator lights up in blue.
