Hi, for all those with the C30, are you having problems keeping the time set. I bought a C30 last month and noticed that the time & dates would reset to defaults when I switch out the battery. I thought it was defective and so I returned it and had them send a new one. The replacement came in and it does the same thing and I have to set the time and date each time I swap out the battery. Anyone else having this issue? I must either be really unlucky or its bad design.
