Prevention of audible control signal transmission
First Claim
1. A communication apparatus comprising:
- receiving means for receiving a communication signal;
transmitting means for transmitting a control signal;
audible output means for outputting an audible output in accordance with the communication signal; and
limiting means for starting a limitation of the audible output according to a transmission of the control signal to another communication apparatus by said transmitting means and for stopping the limitation of the audible output according to a reception of a predetermined signal from said another communication apparatus by said receiving means.

Abstract
A communication system having a radio master and a radio slave for communicating a communication signal and a control signal via a common channel is constructed by a receiver to receive a communication signal, a transmitter to transmit a control signal, and a limiter to limit an output of the signal received by the receiver for a period of time corresponding to a transmission of the control signal and a reception of a predetermined signal by the receiver. The limiter has a key to request the transmission of the control signal and limits the output of the reception signal in accordance with the key operation. The generation of an uncomfortable sound which is caused by a communication of the control signal can be prevented.
