powered-up while making the LED power
adjustments. Cover the photocell to turn the LEDs
“ON” (850nm LEDs will have a slight red glow).
For photocell “On/Off” light-level adjustment, rotate

VR2.

Clockwise is off and counter-clockwise is on.

LED Power and Photocell On/Off Adjustments

Adjust the LED power if they are too bright or too
dim. For IR power adjustment, rotate

VR1.

Clockwise is high and counter-clockwise is low.
