摘要：
A transmission level setting circuit outputs a signal having a transmission level with respect to a portable telephone based on a signal transmitted from a modem unit. The transmission level setting circuit includes a part which receives the signal from the modem unit, and a circuit which automatically outputs a signal having a fixed level regardless of the signal transmission level of the modem unit.
