I have five CR10x. Recently I got problem with (I think) internal batteries. When I change the external battery, the time no longer correct, start from 00:00, date as well and all the store data are gone, but instead there got loads of rubbish data inside CR10x, it is a lot and took about 4 hours to download all. But the program was surprisingly still inside the memory. This kind of thing is happened to three of my CR10x one by one. Why this is happened and how to solve? I am afraid for the rest two CR10x going to happen like this.
