There are many switches, which you can reprogram this "fact", at any time, without.
After a few weeks you start namely again with this study, if you have not programmed this clock daily.
I have it now procured three watches, which also diligently perform their duties, I dread it but again before the next reprogramming.
Now, after 3 months of use, unfortunately, I had to find that 2 of the 3 devices already acknowledged their service.
Probably the installed batteries have given up the ghost, since the internal memory could no longer hold the programming. Although Uhre drew their supply from the power outlets, they could not save or run the input switching times.
The clocks switched to "whim".
I'll watch all return again, because it's just a matter of time before the third clock gives up her mind.
I hope that I can change the clocks to higher-quality devices.
The first given by me 3 STARS I must now replace each 1 STAR !!!
