Installation Guide User Manual

1. INTRODUCTION
This manual provides information about the physical and electrical installation of the EMS-D120
and connected sensors. Additionally, this guide deals with setting up the installation-dependant
firmware options. Because you may not have purchased all the components, you need only read
through the relevant sections of this guide. Information about the operation of this instrument
can be found in the EMS-D120 Pilot’s User Guide.
When properly configured, the EMS-D120 gives an accurate and easy-to-understand display of
engine data. To ensure accuracy in its readings, it is very important that you install the
instrument correctly and perform the specified setup steps. This installation guide will help you
through that process.
OEM Installations
If your EMS-D120 is installed by an OEM distributor, you may find that you are unable to
access some menus and settings. Some Dynon distributors customize various areas of the EMS-
D120 firmware to maintain a consistent pilot experience and minimize integration issues across a
large number of installations. Currently, OEMs can customize access levels to the following
settings on Dynon systems: EMS GLOBAL setup menu, EMS SENSOR setup menu, fuel
calibration, trim calibration, flaps calibration, GPS/NAV setup menu, screen configurations, data
logging, and checklists/data panels. OEM distributors have the option of customizing some or all
of these areas. Please contact your aircraft’s manufacturer if you have any questions about how
your unit has been customized.
Warning
Dynon Avionics’ products incorporate a variety of precise, calibrated electronics. Except for
replacing the optional internal backup battery in EFIS-based products per the installation guide,
our products do not contain any field/user-serviceable parts. Units that have been found to have
been taken apart may not be eligible for repair under warranty. Additionally, once a Dynon
Avionics unit is opened up, it will require calibration and verification at our Woodinville, WA
offices before it can be considered airworthy.
