Claims

[Scope of utility model registration request]

There is a switch that is operated to switch between using earphones (or headphones) and when using the built-in speaker, and a switch that outputs a plow control signal to supply power voltage to each circuit of the radio receiver for a predetermined period of time after the power is turned on. - a timer circuit and a time constant circuit for setting the oscillation frequency of the timer circuit; - changing the time constant of the time constant circuit in response to a switching operation of the changeover switch; A radio receiver characterized in that the setting time of the circuit is changed.
