SERVICE INSTRUCTION
NEW KEY INSTALLATION PROCEDURE
This procedure is for the installation of a new key for the EDM-900, EDM-930 and EDM-960 series Instruments.
This procedure will reconfigure the instrument with the information factory programmed into the new key.
1.
Power down the instrument.
2.
On one side of the instrument you will find a small rectangle label which shows the configuration limits. It
should show the sentence ‘Instrument Limits for: [your airplane]’. Feel this label to see if a large circular
or rectangle hole is being covered. This the access hole to the key. Remove this label (or if you have a
round black cap, remove it instead).
3.
Inside will be a small square pc board that is plugged into a slot. This is the key.
4.
Carefully remove the key and note how it is oriented when it comes out. You will use this same
orientation when you later install the new key.
This key must be returned to JP Instruments at:
