Date and time is lost when the battery is removed.
Is there a battery for date and time back-up? This did not happen when the camera was new. Where is it?

Hi @serene1 ,
Given that the date and time settings are only held for 10 hours if the main battery is removed, it is more than likely that a capacitor is being used to maintain the settings rather than a rechargeable battery.
Without a schematic diagram or a service manual it will be difficult to know where it is.
I have looked at teardown videos of the camera on YouTube but cannot see anything obvious. There's certainly nothing that looks like a battery, directly mounted on the motherboard like they have in other cameras but it may be somewhere else in the camera.

FWIW, the only battery the Owner's Guide mentions is the main power battery. I just upload the manual if you would like to take a look at it.
