Conventional wireless communication devices have a calling function and a receiving function, and the calling function calls the called party.
Further, the incoming call function allows the caller to respond to the caller and make a call (sending/receiving) using the corresponding function.

However, in the above-mentioned conventional technology, it is expected that there will be an incoming call while on standby, and the probability that there will be an incoming call will be estimated when the channel related to the standby is being used by another station and the call is in progress. When the sound was low, I would adjust the volume to a level that would not make the sound inaudible and monitor it.

In this invention, in addition to the normally used first volume adjustment means, a second volume adjustment means for muting the audio signal is provided. Then, when the second volume adjustment means for Miyuto is operated, the volume being monitored is attenuated to a level suitable for receiving incoming call information, and is displayed with an indicator. Furthermore, when the PTT switch is operated, the operation of the second volume adjustment means is stopped, and the wireless communication device is capable of listening at the volume adjusted by the first volume adjustment means, which solves the problems of the prior art described above. It is something.

12d is at the "L" level. Then, when you operate the Miyut button 10 of the hand-shaped microphone 8,
When the terminal 12d becomes "H" level, switch 1 is turned on.
8 operates, and the light emitting diode 11 lights up.
At the same time, the terminal 12c also goes to the "H" level, so the transistor TR turns "on" and performs a mute operation. Then, when the mute button 10 is operated again, the mute control circuit 12 is operated, and when the PTT switch 9 is operated and pushed back during this mute operation, the terminal 12a rises from the "L" level to the "H" level. The flip-flop 15 returns to normal state at the edge, the mute control circuit 12 operates, and the switching transistor TR is turned off.
becomes. Therefore, the amount of attenuation of the voltage-controlled attenuator 4 is the amount of attenuation set by the variable resistor VR, and the amount of attenuation during mute is determined by the resistor R2 . Note that if a variable resistor is used as the resistor R2 , the amount of attenuation during muting can be set freely.

is pressed to answer the caller, and after the caller returns the switch 9, the light emitting diode 11 turns off and the volume becomes the same as the one set by the first volume adjustment circuit 17.
