The signal value is shown only on the display of the receiver profile.
The minimum operating value is 0.5 V, below this value the barrier is in alarm (RED LED
on and GREEN LED off).
To obtain the best signal, orient the optical unit of the receiver in the direction of the
transmitter and vice versa until the best possible value is obtained (the values are to be
considered optimal if greater than 3 V). For vertical adjustments, use the adjustment
screw, while for horizontal adjustments, turn the bracket.
If necessary, help yourself with the viewfinder.
