An electric connector for an endoscope, an endoscope, and a method for assembling an electric connector which make it possible to simplify work operations such as operation checks and repairs of the endoscope, as well as to reduce the time for the work operations. The flexible printed circuit substrate has dummy patterns which are formed, simultaneously with the terminals, on the sides of the connecting part, in a shape corresponding to the outline of both sides of connecting part which are used for positioning the terminals when the connecting part is attached to the connector. The circuit arrangement further includes a counter whose input side is supplied with an input signal which can be derived from the phase signal, and which is coupled to the output of the oscillator. A disruption in communication with the server may occur due to a Call Waiting signal caused by an incoming telephone call. Active termination circuitry is configured to synthesize an output impedance at an output thereof that substantially matches a load impedance to which the output is coupled, the active termination circuitry buffering the analog voltage to the output. The mobile stage system may also be provided with a hitch assembly that can be folded out of view of the audience.
