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.
