C-750 reverts to factory defaults

The camera is set to retain the settings current when switched off. When I change the batteries it resets to the factory defaults. The manual says it will do this if no batteries are installed for more than an hour, but it happens even when there is no delay. The camera seems to work OK otherwise, but I'm going on holiday and don't want to lose any pictures. Any ideas?

Rechargeable batteries, after some use, are known to lose their charge gradually even if it is fully charged to begin with and I have a drawer full of rechargeable that I never use anymore although the manufacturer promised 1000 recharge cycles.

It could be that you battery loses it's power retention in the same way and to the extend that it is barely able to support the memory chip that stores the setting, in the quiet and without you noticing it.

On the bright side, losing camera settings is different from losing pictures files. You won't lose picture files even if the camera setting is lost.

Take along a new set of rechargeable batteries for your holidays and you probably will not have the same problem.

The c-750 has a built-in (non-user replaceable) backup battery to retain your custom settings and date/time. This backup battery has been giving many owners grief as the camera is now reaching more than 5 yrs. old. Apparently, replacement is quite a difficult and fiddly (read expensive) process and is best left as is. Newer cameras now tend to have a user replaceable button cell for this, next to the memory card.

My c-750 suffers from this malady, and each time the AA batteries are disconnected by opening the battery compartment, I have to reset date/time and my settings.

So a fully charged set of AA batteries freshly loaded into camera with correct settings will go back to default if battery compartment is opened and then closed even for just 1 second.

I have written out a cheat card detailing the full step-by-step procedure to reset everything to my liking and placed it in the camera bag where my c-750 lives. Now, replacing with fresh batteries also include a couple of minutes of button pushing and menu navigating. Luckily, as the original question states once reset all seems to work okay.
