When the power is on, the 220v ac voltage will provide IC1-IC6 with +5v direct current working voltage after it is reduced by T, rectificated by UR, filtrated by C1 and C2, stablized by ICO. After the multivibrator A begins to work, IC1's pin 3 will output low-frequency oscillate signals. One serves as IC3's count pulse. The other serves as IC6's shift clock pulse. After IC3 begins to work, the count pulse signals will be counted and frequency-divided. Its pin 12, pin 9, pin 8, pin 11 will output count pulse's 2nd,4th,8th,16th frequency-divided signals respectively.
