Hi, All!

AC/DC 220V~/10v- + internal capacitor about 1000uF.
DS80C310@25MHz + UM62256EM-70LL + M27C2001 + MAX707 +
2 * 74HC373D + 74HC138D + 74HC32D + 2 * AS-9W-K(relay)

Both relays are turned ON(by HC373 via CMBT2222 transistor)
After a few second Power Failure(~AC) the unit sometimes does
not react on the POR pulse, and functions properly while DC
supplying is interrupted.

Thank you,
Oleg
