Specification:

1. IC working voltage: 2.4~3.3V

2. Control mode:

a. Program control: at PM11:00～AM5:00 (PM11:00, PM12:00, AM01:00, AM02:00,

In the time between AM03:00, AM04:00, AM05:00 (the 7 dots do not ring), do not report the time, that is:Do not play the current music.

b. Light control: controlled by photo diode or photo resistor, the time will be reported when there is light, and the time will be reported when there is no light.

c. Close: turn off dotting time

3. Music selection:

a. Cuckoo fixed 5 tones of "cuckoo"

b. Cuckoo (point-to-point pitch and clock)
