Owners Manual

NOTE: The diagnostic pattern consists of a two-digit number being represented by a first group of LED blinks (1–9) in
amber, followed by a 1.5 s pause with the LED off, and then a second group of LED blinks (1–9) in white. This is then
followed by a three second pause, with the LED off, before repeating over again. Each LED blink takes 0.5 s.
The system will not shut down when displaying the Diagnostic Error Codes.
Diagnostic Error Codes always supersede any other use of the LED. For instance, on Notebooks, battery codes for Low Battery or Battery
Failure situations will not be displayed when Diagnostic Error Codes are being displayed.
