What is the purpose of the P12 SD card?

I bought a used P12 and I’m curious about the included SD card. Is it used by the P12 on an ongoing basis or is it included to facilitate a firmware update? I’d like to update my P12 but don’t have a standard SD card, I only have unsupported types.


The SD card slot is for loading firmware updates.

Any SD card can be used for updating but the card must be formatted FAT32.

Thanks, so I’ll just use the included card.

From a cybersecurity perspective, it is a very bad practice to insert an SD card of unknown origin into your PC. If it were me, I would destroy that SD card and use one I purchased myself.
