A process for registering lines of termination with indicia in a transported sheet of web material is disclosed. The ray launching method calculation unit calculates a first piece of radio wave propagation characteristic estimation data in which a radio wave propagation characteristic from a radio wave transmission point to a building with a radio wave reception point is estimated, using a plan view data. A current sink transistor is coupled from the output of the dual-mode charge pump to a ground reference through a current sink control switch transistor that is turned on by the optional pull down control signal.
