 Note: The AED/CED caution lamp is switched on
if an engine reading is in the amber or red
range.
The AED/CED caution lamp remains on
even when the parameter returns to the
green/normal operating range and must be
confirmed by pressing the Confirm/Test
knob.
After being confirmed, the AED/CED cau-
tion lamp will switch on again whenever
another parameter enters amber/red range.
Pressing the Confirm/Test knob longer than
one second will initiate the power-up test
sequence.
