If the setting of the sensitivity is not possible (e.g. object signal
and background signal are about the same), the red LED flashes
after step 3 for approx. 2s. The unit then passes into the operat-
ing mode with the sensitivity being unchanged.
Setting of the maximum sensitivity
• Go into the programming mode (step 1).
• Align the unit so that no light is reflected.
• Press the setting button twice (see steps 2 and 3).
During the measurement (approx. 1s) allow at least two objects to
move through the sensing area of the lens.
Press once.
The yellow and green LEDs go out for approx. 1s,
then flash again alternately.
