D. The EDC is installed. This should be installed (with the connectors pointing down) on the inside of the
cockpit or in an instrument bay. For a twin-engine aircraft it can be installed on the backside (not the engine
side) of the firewall. The EDC should NOT be installed in a location where it can be pressure washed.
E. The Wire Harnesses are installed. The wire harnesses for the EDC and MVP are pre-wired and included
in the kit.
F. Field Calibration/Setup steps are performed. Weight & Balance, Fuel Tanks, Horsepower, etc. Functions
are calibrated/setup. Calibration/Setup requires a password. See the following Password Protection section
for more information.
G. System Checkout is performed.
1.4 Password Protection:
The MVP provides a number of screens for the pilot to use during flight, none of which require a password. It also
provides many System Configuration Screens that are used to configure the MVP for a specific aircraft. Some of the
aircraft functions (fuel level, flaps, trim, weight and balance, etc.) MUST be calibrated during installation and some
must be set at the factory or by an OEM.
The MVP provides two levels of passwords for configuring and calibrating the unit.
1.4.1 Level #1 Password (Maintenance):
The Level #1 password is for the installer or maintenance personnel. This password allows the
installer to perform the following:
A. Delete Log Files.
B. Set up the Gear Warning.
C. Adjust the Recovery Factor.
D. Calibrate the Fuel Level for all fuel tanks.
E. Adjust the aircraft’s Weight and Balance data.
F. Set the Fuel Weight, Tach Time and Engine Hours.
G. Set up the Serial Ports.
H. Disable the Bar Graph.
I. Calibrate Pressure Altitude.
J. Calibrate Flap and Trim indications.
For a non-certified MVP, the password is “100.” For a certified unit the password must be obtained from
Electronics International Inc. To qualify for the maintenance password you must be a certified mechanic or
FAA approved shop.
The password protects the MVP from unauthorized access to calibration data. If calibration data is
improperly changed, it could lead to engine or aircraft damage and/or personal injury. Once the MVP is
installed and checked out, the password should be changed (on either the certified or non-certified unit) to a
unique number and it should be protected from unauthorized access.
If the new password is lost or a new shop requires access to calibration data (as allowed by the Maintenance
Password), Electronics International has a method of providing the Maintenance Password to any
authorized shop or personnel.
