Rob, it doesn't even take that to reset the camera. Just press the battery check button behind the palm door. I hear the lock on the battery tray is breakable.
The error kills any flash shots. Trust me. Usually when you get the error and aren't using flash the picture actually is recorded. Not so with flash. To me that makes the T-90 a useless hunk of junk. I gave my only T-90 away.
In life you only get one great dog, one great car, and one great woman. Pet the dog. Drive the car. Make love to the woman. Don't mix them up.
