Installation Manual
To activate an optical switch, block the light by holding your thumb or finger in front
of the opening.
You can activate the optical switch through the lens. Do not remove the transmitter
housing cover.
Important
The transmitter only detects one switch selection at a time. Be sure to place your thumb or
finger directly over a single optical switch, and ensure no other switches are being obstructed.
