Alarm hierarchy
When a measurement limit is reached, the pilot can momentarily tap the STEP button on the EDM-960 instrument to
extinguish the particular flashing alarm acronyms. If another measurement has also reached its limit, that label will
then begin to flash. The pilot should continue to monitor the affected parameters (just as he would using a
conventional analog display that had reached a limit). The bar graph functions of CHT, EGT, and TIT remain displayed
for easy reference should one of these limits be reached.
