Rispondi a "Why does my camera not hold the date and time?"Had the same problem with my Canon Powershot SX20 IS. Found this little battery compartment that holds the CR1220 on the bottom of the camera inside where the main batteries are installed. Just open the bottom battery compartment and you will see the small little part you need to slide off. You may need a small flathead screwdriver. Hope this helps someone else out there.
