• The DUSK control determines the level of darkness required for the unit to start
operating. The setting is best achieved by the procedure below;
1. Set the DUSK control knob fully anti clockwise.
2. When the ambient light level reaches the level of darkness at which you wish
the lamp to become operative (i.e. at dusk) SLOWLY rotate the control in a
clockwise direction until a point is reached where the lamp illuminates.
3. Leave the control set at this point.
• At this position the unit should become operative at approximately
the same level of darkness each evening.
• Observe the operation of the unit. If the unit is starting to operate too early
(i.e. when it is quite light) adjust the control slightly anti-clockwise.
If the unit starts to operate too late (i.e. when it is very dark).
Adjust the control slightly clockwise.
• Continue to adjust until the unit operates as desired.
Masking the Sensor Lens
• To restrict the sensor coverage, preventing detection in unwanted areas, mask
the sensor lens using the masks provided in the accessory pack (See diagram I).
• The top section of the lens covers long range detection, the bottom covers
short range. Similarly the left and right lens sections cover the left and right
detection areas respectively.
