The LED orientation light is switched on if
the range of detection is entered and the

Setting behaviour for close-up range
Mode 1: When motion is detected in the
close-up range, the room lighting is switched
on for the duration of the delay time. Further
motion in the close-up range switches the
room lighting off and the LED orientation
Mode 2: When motion is detected in the
close-up range, the room lighting is switched
on for the duration of the delay time. Further
motion in the close-up range switches the

Setting brightness threshold
Either one of four pre-defined brightness
thresholds (see table IR remote control func-
