• Set the light threshold to maximum (fully clockwise/
Sun end), then turn the control anti-clockwise
about three quarters of the way round to the
Moon end. This will give operation after
DUSK approximately.
• For a more accurate setting of the DUSK/DAWN
LEVEL ADJUST control turn it fully anti-clockwise
(Moon end) and leave for at least 20 seconds for
the unit to settle.
• When the ambient light level reaches that required
for DUSK, adjust the DUSK control a small amount
11
clockwise pausing to try to get the unit to detect
and turn the lights under control ON by moving
a hand slowly backwards and forwards across the
front of the detector lens for around 5 seconds.
• Continue to turn the control small amounts in
a clockwise direction, stopping after each
adjustment to try to get the unit to detect as above.
• Eventually detection will occur and the DUSK level
is now set as required.
