❒

Loosen the wing screws, estimate the direction to aim the sensor and tighten
the wing screws just enough to hold the sensor in place.

❒

Walk through the coverage area noting where you are when the lights turn
on. Loosen the wing screws and readjust the sensor as necessary. Tighten
the wing screws (finger tight) when you are satisfied with the coverage
direction. If you have not already tightened the locknut against the base
plate, do so now.  Keep the sensor at least 1 inch (25 mm) from lamps
and keep the controls on the bottom.

❒

Adjust SENSITIVITY as needed to increase or decrease the range. Too
much sensitivity may increase false triggering.

❒

Set the amount of TIME (1, 5 or 20 minutes) you want the lights to stay on
after motion is detected at night.

❒

If you need to detect objects more than 70 feet (21 m) away, turn Range
Boost on.

❒

Replace the rubber cover to protect controls.

The sensor is less sensitive to motion directly
towards it, most sensitive to motion across its field
of view.
