Hi, Audiguru and Nigel,
the final version arrived at by Nura100 and manoj is powered completely by Bty and nOT bty standby. theereby the clock continues to work as standalone. Depending on ones own necessity, the design is modified. we can change societies but not overnight. one cant expect to reach UK,US and Canadian standards even with sicere attemps, the developing countires have to be stable and self suffiecent and we may have to encourage them towards standards. Perhpas you may appeciate, it takes time.
