* If you get confused while switching modes, turn the
power off for one minute, then back on. After the calibration time the control will be in the AUTO mode.
Dual Light Level Timer
Light comes on half bright for selected time after dusk
(Off, 3 hr., 6 hr., until dawn). Selecting OFF disables
this feature. The motion sensing features will continue
to work as described in this manual. If motion is sensed,
the light turns on full bright for the ON-TIME (1, 5, or
20 minutes) then returns to dim mode.
For easy installation, select an existing light with a wall
switch for replacement.
For best performance, mount the fixture about 8 ft. (2.4 m)
above the ground.
8 ft. (2.4 m), aiming the sensor down will reduce coverage
distance.
