Every time we take a picture, a red F appears on the screen and we have to shut the camera off and turn it back on each time we want to take a picture. The camera is also not saving pictures

I think you can download a user manual from here:-

I had a quick look at the manual and on page 8 it states:-

If icon red F appears on the screen, this is an indication that the internal memory is full. No further
photos can be taken until the existing photos have been downloaded and cleared from the camera
memory.

You need to empty the camera's internal memory (Download the manual) or insert an SD card, this camera can take up to a 2Gb standard SD card. Needs to be formatted with FAT 16 file system.
