    SELF-DIAGNOSIS FUNCTION The self-diagnosis function consists of error codes for users which are displayed automatically when errors occur, and error codes which show the error history in the test mode during servicing. For details on how to view error codes for users, refer to the following box in the instruction manual.
  • Page 4 ITEM OF ERROR HISTORY MODE ITEMS AND CONTENTS Selecting the Test Mode Display Details of History total rec Displays the recording time in the form of “rππππππh”. The displayed time is the total number of hours the laser is high power, which is about one-fourth of the actual recording time.
