The units in this manual contain a self-diagnostic function. If an error occurs, the POWER LED will automatically begin to flash. The number of times 
the LED flashes translates to a probable source of the problem. A definition of the POWER LED flash indicators is listed in the instruction manual for 
the user’s knowledge and reference. If an error symptom is difficult to reproduced use the Remote Commander to display the record that is stored at 
the internal NVM to specify the cause of the failure.

Diagnostic test indicators
When an error occurs, the POWER LED will flash a set number of times to indicate the possible cause of the problem. If there is more than one error, 
the LED will identify the first of the problem areas. If the errors occur simultaneously, the one that corresponds to the fewest flashes is identified first.
Results for all of the following diagnostic items are displayed on screen.  No error has occurred if the screen displays a “0”.
