Section 10 - Custom Key Card
The EDM contains a Key Card which customizes it for your aircraft.
This card defines fixed primary instrument limits and ranges, EDM
serial number and make, model and year of your aircraft. You
cannot exchange it with any other EDM. Typical parameters include:
oil temp, oil pressure, fuel pressure, fuel quantity, cylinder head temp,
turbine inlet temp, manifold pressure, and RPM. Do not remove the Key
Card from the instrument. If your EDM should ever have to be replaced
with a different unit, the factory will reprogram your Key Card to match
the new serial number. Always confirm that your aircraft make and
model are initially shown in the RAD upon power up.
