Immediately after power-up, three of the green LEDs should illuminate steadily for

several seconds. Then the USB LED should flash three times. Irregularity of the

LED during this LED test may mean there is a problem with the LED itself.

The actual component tests immediately follow the LED tests. A normal (no fault)

result is signaled by a flashing of the USB LED, followed by a darkened LED.

If the Self-Test routine detects any component error, then following the LED tests

the Self-Test will halt and the LEDs will continuously signal the error according to

the following table.

When the DP-G321 is powered ON, it also automatically performs a Self-Test on

each of its major components. The final result of the Self-Test is signaled by the

state of the USB LED indicator following the Self-Test. Preliminary to the actual

component tests, the LED indicators are tested to confirm their steady and flashing

operation.
