3-16. AUTO CONVERGENCE ERROR CODE LIST
If an error code is displayed after the set has been fully adjusted, correctly, plese check the following items : position, tilt and sizing. If
either of these adjustments are off, even slightli, the auto registration pattern will not hit the four sensors properly. This occurs when the
internal generator patterns is being flashed on the screen for the sensor 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.
