If an error code is displayed after the set has been correctly adjusted, check the following items: position, tilt and sizing.  If any of these adjustments 

are off, even slightly, the auto-registration pattern will not hit the four sensors properly. This occurs when the internal generator patterns are being 

flashed on the screen for the sensors to read.  Therefore, auto registration (called auto convergence) cannot operate properly, causing an error code to 

be displayed. In order for this function to operate properly, position, tilt and size must be adjusted properly.
