To adjust the light sensitivity setting, set “Turn-On” knob to center
position.
If lamp turns on before the desired darkness level is reached (i.e. early
dusk),
adjust knob clockwise. If lamp turns on after the desired darkness level is
reached, adjust knob counterclockwise.
Note:
The Light-Sensing Timer requires a certain amount of surrounding
light during the day to reset. Some applications may require initial knob
adjustments to ensure re-set conditions are met so your Light-Sensing
Timer will operate properly. See troubleshooting section for details.
TROUBLESHOOTING
Problem:
Control turns on at dusk during the rst night of operation but
does not turn on at dusk during the second night (or second timing cycle)
of operation. This means the Light-Sensing Timer did not see enough light
during the daylight hours to reset. This problem usually occurs on cloudy
or overcast days when there is no sunlight.
Solution:
Move Light-Sensing Timer closer to a natural light source
and/or adjust the “Turn-On” knob clockwise. Repeat on subsequent nights
if necessary.

at the middle switch position. The Light-Sensing Timer should turn on after
photocell eye sees darkness or after photocell eye is completely covered.

OPERATING DESCRIPTION:
Your Light-Sensing Timer is activated by changes in
surrounding light. For optimum performance, the
Light-Sensing Timer should be positioned in an area
exposed to a strong source of natural light. For indoor

applications, ideal positioning is in a lamp xture located within 4 ft. of a
window or other light source.
Once power is supplied to your Light-Sensing Timer, the control will turn on
at dusk (or when the surrounding light level becomes low enough) and then
turn off after the selected time period. Once the bulb automatically turns off,
it will remain off until the following night. At dusk on the following night, the
Light-Sensing Timer will once again turn on, then turn off after the user
selected time period. As long as power is supplied to the control, the
Light-Sensing Timer will continue to cycle on and off in this manner.
INSTALLATION (For use indoors or in enclosed xtures)
1. Turn "OFF" power to light xture.
2. Screw Light-Sensing Timer into light xture.
3. Screw bulb into Light-Sensing Timer.
4. Position control so that the photocell eye faces a strong source of light.
5. Turn "ON" power to light xture (middle setting for 3-way lamp).
Light-Sensing
Timer will begin to operate in 30 to 60 seconds.
