1. Set the multimeter to the DC voltage scale and insert the tips into the test terminals (RECEPTION LEVEL) on the receiver,
obeying the polarity;
2. Adjust the horizontal angle and the vertical angle until the test terminal voltage rises to the maximum;
3. Check the alignment table (located inside the front cover of the receiver) for the voltage levels indicated for each type of
environment.
Higher voltage levels ensure smooth operation and prevent false triggering, caused by fog and other
climate changes. The desirable voltage values must be between 3 and 4 Vdc.
5. Tests
After installation, confirm correct operation by testing the beam cut. Block the beams with your hand or some screen and
check if the receiver triggers by observing the alarm signal by the LEDs, as shown in the following table:

5.1. Response time adjustment (receiver only)
Adjusts the interruption period by setting the speed level. Level 1 is the highest speed and level 5 is the lowest speed.
Factory default: level 3. It must be kept in mind that in outdoor environments birds can cut the beams and cause false
alarms. Therefore, adjust the response time so that the sensor does not detect a bird, but is able to detect an intruder. Do
the simulation by cutting the beams by hand at different speeds.
Run at full speed
Level 1 and 2 - (50ms)
