the user’s knowledge and reference. If an error symptom is diffi cult to reproduce use the Remote Commander to display the record that is stored at the
internal NVM to specify the cause.

(Results for all of the following diagnostic items are displayed on screen. No error has occurred if the screen displays a “00”)
