COMMUNICATION DEVICE WITH A MULTI-FUNCTIONAL CONTROL

摘要

Systems (100) and methods (400) for controlling functions of a Radio Transceiver (206, 208). At least one function is controlled in response to: a depression of a center of an elongated roller of a control element (102, 300); a depression of a first peripheral edge portion (FPEP) of the elongated roller (302) for a first period of time; a depression of a second peripheral edge portion (SPEP) of the elongated roller for a second period of time; a rotation of the elongated roller around a central axis thereof; a depression of the FPEP (352) for a third period of time that is longer than the first period of time; and/or a depression of a SPEP (354) for a fourth period of time that is longer than the second period of time.
