NOTICE
If manual reset is selected, do not connect RESTART SELECTION.
As soon as the choice of mode is detected by the transmitter, the receiver is always in alignment mode on
start-up (see chapter 8.2 "Aligning the sensor") in order to then switch to the selected mode after the first
correct alignment.
CAUTION
Carefully assess the risk conditions and the RESET mode!
Automatic RESET mode is potentially unsafe when guarding access points in danger zones if it
is possible for the user to completely pass beyond the area being monitored.
