If the power supply microprocessor detects a malfunction, the DC IN icon blinks orange. The blink pattern indicates an error as shown below.
Start
Error code (8 bit) “1” “0”
Interval between data bits
The error code begins with LSB (Least Significant bit)
Example: Error code 11h (Error codes are given in hexadecimal format.)
