Position 'T'
Postion 'T' activates the calibration process.
The LED 'AlarmT' respectively 'AlarmR' light up
simultaneously for the duration of the calibration.
During this time, the protected area must be clear.
If defect or covered elements are detected, the
number of elements is shown by either the AlarmR
LED flashing for receiver elements or the AlarmT
LED flashing for emitter elements.
For example: If the LED AlarmT flashes three times
after calibration, three of the emitter elements are
either covered or defective.
