How do you update the firmware of Fuji S7000?

What you do is have an ac mains adapter or a fully charged battery, a formatted card in your camera ( there should be a setting in your cameras menu for formatting) and the usb lead connected to your camera and pc. This should all be in your owners manual if you have one ( if not you can download one from a fuji website).
Check for a firmware update on a fuji website ( I had a look on a few and didn't find one) and down load it to your computer.
To check your current version hold the display back button down and turn the camera on. It should display the current version and ask if you want to up grade. If you don't ,or can't, turn off your camera.
Basically you down load the up date, then up load to your camera using the usb lead following any instructions along the way (get the manual for instructions. It will be easier). Mains lead is preferable as a battery could die halfway through and then you will be in trouble.
Hope this helps
