OS-01

Selective Collective Operation

The momentary pressing of one or more car buttons sends the car to the designated landings in the order in which the landings are reached by the car, regardless of the sequence in which the buttons are pressed. Throughout this operation the car answers calls from the landings that are within the prevailing direction of travel, and every call is cancelled once answered.
