いる前記所定時間だけ行なわれる。On the other hand, if this reception channel display is specified,
At the same time as the selector switch 13 is switched to the receiving channel display side, the counter 8 that counts time based on the commercial power frequency starts counting operation, and after a predetermined period of time (for example, several seconds) has passed, the switch circuit 12 is switched on. Generates a control signal to turn off. Upon receiving this control signal, the switch circuit 12 turns off and stops supplying the character signal representing the receiving channel to the adder circuit 4. therefore,
The reception channel is displayed only for the predetermined time set in the -counter 13.
