8. SYNCHRONIZATION
As soon as the barriers are switched on they synchronize in a time between 1 and 10 seconds. If syncronization is OK
the Buzzer (make sure that is enabled, dip1 receiver On) after some seconds becomes OFF. If it doesn't happen (buz-
zer already on) verify the setting of range and the proper mechanical alignment of the barriers.
After the syncronization the led on the receiver flashes to indicate the quality of reception: see table.
1 flash
2 flashes
3 - 4 flashes
9. FUNCTIONING
Every receiver checks the direct beam and the oblique ones (upper and lower), this ensures the protection against false
alarms caused by small objects and bugs.
