A rapid thermal processing apparatus comprises a processing chamber which subjects a semiconductor substrate to rapid thermal processing. The connector includes an elongated bracket with groups of openings and a number of clips which are attached to the bracket by use of the openings. The system compares the device’s current location with a set of location points stored in a database and associated with one or more underground facilities. Locking mechanism locks the first leg relative to the base member in the installation position, and adjusting mechanism adjusts the position of the angular bracket member in at least a transverse direction perpendicular to the longitudinal direction of the frame piece of the window frame. A communication device, a method of controlling a transceiver arrangement, and a computer program are also disclosed.
