PROBLEM TO BE SOLVED: To make a radio communication equipment to be compact with the reduction of the number of output ports in a control part, to reduce the cost and to improve operability with the arbitrary setting of an output adjusting range. SOLUTION: The radio communication equipment is provided with a speaker 17 giving information on a reception state in a radio communication part, a control part 100 outputting a control signal for controlling the speaker 17 and an amplifier circuit 12 adjusting the sound volume of a radio reception part with the control signal outputted from the control part 100. The speaker 17 giving information that a system is in the middle of reception is operated by using the same control signal and the sound volume of a radio can be adjusted. A power amplifier outputting the transmission output of the radio communication part, the control part 100 outputting the control signal for controlling transmission output and the amplifier circuit 12 adjusting the sound volume of the radio reception part with the control signal are provided. The power amplifier is operated by using the control signal and the sound volume of the radio can be adjusted by the same control signal. |
