CONFIGURING AND SETTING YOUR CLOCK
Apply 9-12VAC.
The clock will display '50' or '60' for 3s, depending on the AC power
frequency (Hz) in your area. This indicates that the zero cross detection part
of the clock circuit is working fine.
(If the clock displays '00', you either applied a DC voltage instead of an AC
voltage, or there is a problem with the zero cross detection circuit T1, R1, R2,
R6, C3, D5)
