Unpacking and Installation
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 accordi ng to the following table.
In the event of any such error signal, contact your dealer for
correction of the faulty unit.
