in the instruction manual. For details on how to check error codes during servicing, refer to the following “Procedure for using the Self-
Diagnosis Function (Error History Display Mode)”.
Self-Diagnosis Function
The deck’s self-diagnosis  function  automatically  checks the condition  of the MD deck when an error occurs, then issues a
code and an error message  on the display .  If the code and message  alternate,  find them in the following  table and perform
the indicated  countermeasure.  Should the problem persist, consult your nearest Sony dealer .
