Power On Self-Test
When the DP-300 is powered on, it 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 LPT1, LPT2, and COM LED indicators following the self-
test. Preliminary to the actual component tests, the three LED indicators
are tested to confirm their steady and flashing operation.
Immediately after power-up, all five of the LED’s should show steady green
for several seconds. Then the LPT1, LPT2, and COM LEDs should flash on
simultaneously three times. Irregularity of any of the three LEDs during
these LED tests may mean there is a problem with the LEDs themselves.
Contact your dealer for correction of any LED problems before proceeding.
The actual component tests immediately follow the LED tests. A normal
(no fault) result is signaled by a series of three cycles of sequential flashing
of the three LEDs, followed by a quiescent state with all three LEDs dark.
If the self-test routine traps any component error, then following the LED
tests the self-test will halt and the LED’s will continuously signal the error
according to the following table. In the event of any such error signal,
contact your dealer for correction of the faulty unit.
