Is a new set. But if the battery kong, should be all my preset all gone. but the preset is there. Just after press 'Tuner' have to press 'number' for my preset station. Is one more step extra, compare to all my previous HIFI, so long as you press Tuner, it should start at your last listening station.

All my configuration is still there, so guess no much on the battery-gua.....

Any user using this model can share? I guess all the htz series should be same design. Just wonder....why?
