Using Finger Touch Interactivity
You can use your finger to perform the same functions as the interactive pens when you install the
Touch Unit.
Note: See the online Installation Guide for detailed instructions on installing the Touch Unit (BrightLink
1485Fi+). If your product did not come with a Touch Unit, you can use a compatible Touch Unit that you
already have or you can purchase one as an optional accessory (BrightLink 1480Fi+).

projectors or devices.
A built-in, high-power laser is emitted from the laser diffusion ports on the bottom of the Touch Unit.
Follow these precautions when using the Touch Unit and finger touch interactivity:
• Children using finger touch interactivity should always be accompanied by an adult.
• Never disassemble or modify the Touch Unit. Never open any cases on the projector or Touch Unit.
Electrical voltages inside the projector can cause severe injury.
