Question about Canon EOS 400D / Rebel XTi Digital Camera
You can reset all your settings and clear errors by removing the battery pack and also under the camera is an access screw to get to a button battery or two. The type of screw you use a dime or quarter to open. With the battery pack out, remove the button batteries and leave all those out for several minutes and then with the batteries still out, activate the On switch for your camera and leave it in the full on position for 30 seconds. That should drain off all residual power from the circuit board inside. You will have to reset everything, such as your personal settings in Tools and the time and date setting. All of those user set items, but your error message should clear too. If you get the error message again, right away, after reinstalling the batteries and battery pack, then you have damaged the Flash Unit... but I doubt that. Canon makes a good camera and I don't think what you describe would cause that problem.
