Adjustment
• If you find that the light switches on when it is
too dark, turn the light level adjuster towards
early and if the light is in operation when
it is too light turn the adjuster too late.
Notes:
• The security switch has a built-in delay function
to ensure that momentary changes in the light
do not switch it on.
• The hours shown on the dial are only approximate
guides, do not expect great accuracy.
• Once the switch has turned on and the programme
has turned OFF after the required number of hours,
it is important not to allow artificial light to fall on it,
followed by a period of darkness. This will fool
the switch into thinking it is dark again and it will
operate. Care should therefore be taken to prevent
light falling onto the switch, e.g. table lamps.
