to OFF, perform a complete cy-
cle (opening/closing) and pro-
ceed to the required variations.
Check Battery connection and
efficiency of the battery charg-
er.
Remove obstacle from Sensor
or Photocells detection range;
check efficiency of detection
devices.
Check connection and effi-
ciency of the battery operated
anti-panic device.
Remove the obstacle.
