動定義為“開始”（即enable）的開關后，一排指示燈變亮，之后搶答開始，有4個扳動開關代表4個搶答器，數碼管將顯示出最先被扳動的開關的序號，同時發出聲音，表示搶答成功。若未按“開始”前，有任意開關被扳動，則數碼管顯示被扳動開關的序號，并發出另一種聲音，表示有人搶答

eached for the definition of "start" (enable) the switch, a row of bright lights changed, after Responder, a four flick of a switch on behalf of four Responder, digital controls are to be shown first to be reached for the switch serial number, also issued voices saying Responder success. If the failure to "start" before it was switched on the flick, Digital Display was the flick of a switch the serial numbers, and issued another voice, someone Responder.
