2-15. AUTO REGISTRATION ERROR CODES
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 ß ashed
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 correct position, tilt, and size must be adjusted properly.
