To select a specific part to test, you can press the ESC key to cancel the Quick Test and select the Thorough Test Mode instead. Back to Top

This means the LED indicator consists of two groups of numbers for each color. The first number corresponds to the number of Amber blinks from the LED. (from 1 to 9 blinks)The second number corresponds to the number of White blinks from the LED.
