ミユート回路。 In a multichannel access system consisting of one control station, multiple mobile stations, and a command station, in which multiple users can use multiple radio frequencies at the same time, the mobile station and command station each have a polarity inversion circuit on the output side of a press switch. and a timer circuit in series, and an I/O circuit via the microcomputer section.
A notification sound mute switch is inserted into the output circuit of the notification sound suitable for the line condition specified by the control station sent from the /O port section, and the operator of the local station detects the reception state without starting transmission for a certain period of time. A notification sound muting circuit for multi-channel access, characterized in that when the notification sound continues, the notification sound is muted.
