<p>PROBLEM TO BE SOLVED: To make adjustments and settings safely, securely and easily while a display unit kept be mounted by operating one operating means which has plural operation positions and performing control so that plural adjustment items can be set. SOLUTION: A multiswitch 103 is an operating means for making various settings and has multiple contacts corresponding to plural operation positions. The microcomputer 115 of a control means detects the movement of the multiswitch 103 through a transducer 116 and controls an electronic variable resistor 104 and a sound controller 105. An electronic variable resistor 109 added to a decoder 108 is controlled to set picture quality and a mode for setting a combination of predetermined sound quality, picture quality and an adjustment value at one time and also selectively implement plural modes. Further, characters of confirming the mount state and safety of a display unit and the rest of a battery are displayed on a character display means 110. The transducer 116 is composed of ladder resistances, etc., and transduces the operation of the multiswitch 103 into an electric signal.</p> |
