A frequency converter includes a symbol string editor in which the potential input symbols are grouped into at least two symbol lists. One of the lists is treated as a current symbol list, which can be scrolled and from which the symbols can be selected as the user input. In addition, a user is allowed to control change of the current symbol list such that the symbols in all of the symbol lists are available for selection. This arrangement allows for scrollable lists to be significantly shorter than a single list of potential symbols would be, which makes entering symbol strings faster.

Equipment for distribution of electric power

A method and apparatus for verifying destination calls needed in an elevator system. In the method a person having entered a destination call is identified first on the floor level outside the elevator and again in the elevator car allocated to the person. The destination floor call received from a destination call device as well as starting floor information obtained from a detector used to identify the person having entered the call are transmitted to the elevator control system, which, based on the destination call, allocates an elevator to the person having entered the call. If the system identifies the person having entered the call when the person is in the elevator car, then the destination call is acknowledged in the system as executed. On the other hand, if the person having entered the call is not identified in the elevator car allocated to him/her, then the previously entered destination call is kept valid and a new elevator is allocated to the person having entered the call.
