Locking/unlocking the lock can be done in the following two ways:
• From inside with the handwheel: In idle status, the door lock drive is
disengaged, i.e. mechanically separate from the key. By turning the hand-
wheel of the door lock drive, the lock can be locked or unlocked and the
door can also be opened. The function of the handwheel is therefore the
same is if you used a "normal" key. The door lock drive must be in idle
status (motor not moving).
• From outside with a key: In this case, a lock cylinder with emergency and
hazard functionality (double cylinder) is required, otherwise a key inserted
from inside will block any actuation of the lock cylinder. The lock can (if a
lock cylinder with emergency and hazard functionality is used) be locked or
unlocked from outside or the door can be opened with a key. The door lock
drive must be in idle status (motor not moving) in this case.
Do not tighten the screws that fasten the radio drive to the base too tight,
since it might jam the drive and make opening from outside difficult.
