Keep Number 1 switch at OFF location.
New setting will take effect after restart (disconnection and reconnection of the battery).

Power to lights may be programmed to turn ON at different ambient light conditions. Programming is accomplished by setting the DIP switch, positions 2, 3, and 4. Refer to the chart below. If it is desired to turn ON the lamp/load only during dark conditions, set the DIP switch to CDS Light Sensor Degree 1, 2, or 3. If it is desired to turn ON the lamp/load under more illuminated conditions, set the DIP switch to CDS Light Sensor Degree 4, 5, 6, or 7.

To disable the ambient light sensor — thus providing power to the lamp/loads all the time — set the DIP switch for the CDS-Light-Sensor Degree to “0”.

To enable the CDS Light Sensor Degree selections, it is necessary to remove the battery connections for 10 seconds and reconnect. The solar panel is utilized as the CDS Light Sensor.
