SELF DIAGNOSTICS
A blinking red and yellow Status LED will indicate an Error Code that can help determine the cause of a circuit failure.
• The number of Red blinks indicates the value of the MSD (tens digit) of the Error Code.
• The number of Yellow blinks indicates the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “37”, the LED will continuously blink Red three times, followed by blinking Yellow seven times.



See the following for a list of Error Codes.
To perform a System Reset, press and hold the Power button for 10 seconds. Or, unplug the set for 10 seconds then restore power.
