Secton 17 - Calbraton Problems
F52:NOT CALIBRATED
This message is a catch-all code which indicates an improper calibration sequence or that one
of the phases of calibration was not completed. The skipped phase must be completed or the
calibration sequence must be passed through in proper sequence before this message will clear.
Re-start the calibration sequence and proceed through each sequence in the specified order.
A “Redo” prompt will appear before each sequence. Answer “NO” if there is no reason to repeat
or “YES” if the phase must be completed.
