1. INTRODUCTION
Thank you for purchasing the Dynon Avionics EMS-D120. This section provides some important cautionary information
and general usage instructions for this manual.
Before You Fly
We strongly recommended that you read this entire guide before attempting to use the EMS-D120 in an actual flying
situation. Additionally, we encourage you to spend time on the ground familiarizing yourself with the operation of the
product. While first learning to use the instrument in the air, we recommend you have a backup pilot with you in the
aircraft. Finally, we encourage you to keep this manual in the aircraft with you at all times. This document is designed to
give you quick access to information that might be needed in flight. CAUTION: in a flying situation, it is the pilot’s
responsibility to use the product and the guide prudently.
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.

2. PRODUCT OVERVIEW
This EMS-D120 monitors your engine and other vital aircraft systems and displays information in an easy-to-read
format. This section provides a general overview of the various parts of the EMS-D120 as well as a theory of operation.
The information in this section serves as a reference only and helps familiarize you with the inner workings of the unit. It
should not be used for diagnostic or reparative work.
EMS-D120 Hardware
The EMS-D120’s versatile design accommodates a wide range of engines and sensors. You may configure the system to
meet your monitoring requirements covering both air- and water-cooled engines with up to six cylinders. Its warning
capabilities provide early notification of problems that might otherwise go unnoticed.
POWER
The EMS-D120 requires between 10 and 30 volts DC for operation. It is acceptable to have the EMS-D120 turned on
during engine start.
SENSORS AND INPUTS
When connected to the appropriate sensors, the EMS-D120 displays RPM, manifold pressure, oil temperature and
pressure, exhaust gas temperature (EGT), cylinder head temperature (CHT), fuel levels for up to 4 tanks, voltage,
current, fuel pressure, fuel flow, carburetor air temperature, coolant pressure and temperature, outside air temperature,
flaps, trim, and the status of up to two external contacts. Fuel endurance and economy information can be obtained when
a compatible GPS unit is connected to your system.

Product Overview
DYNON SMART AVIONICS BUS
If you have multiple Dynon Avionics products in your aircraft, they may be networked together via the Dynon Smart
Avionics Bus (DSAB). Units networked via DSAB have the ability to transmit information to each other. Any product's
data can then be viewed on any other screen in the DSAB network. For example, an EFIS has the ability to display
engine monitor information if it is connected to an EMS or FlightDEK-D180.
Note that the failure of a unit in a DSAB network may cause the loss of some or all data shared between units. In the
above example, if the connected EMS/FlightDEK-D180 were to fail, the EFIS would no longer be able to behave as an
engine monitor. For more information on DSAB-specific alerts, refer to the DSAB Alerts section on page 5-4.
OUTPUTS
The EMS-D120 has outputs to drive external customer-supplied audible and visual devices for engine, AOA (if installed)
and altitude alerts.
A connected HS34 or AP74 can output voice annunciations for many of the alerts generated by the EMS-D120.
DISPLAY
The display is a 7-inch, 854 by 480 pixel, 400 nit or 800 nit LCD screen, depending on the model.
BUTTONS
User interaction takes place via the six buttons along the bottom of the front panel of the unit.

3. PRODUCT OPERATION
After reading this section, you will be familiar with the basics of how to use your EMS-D120. For details regarding
specific procedures (e.g., adjusting display brightness, using the fuel computer, setting the clock, etc.) please refer to the
EMS Operation section.
Front Panel Layout
All normal operation of the EMS-D120 happens via the front
panel. The front panel contains buttons and a display.
Buttons – There are six buttons on the front panel of the
EMS-D120. Throughout this guide, these buttons are
referred to as one through six, with button one being the
leftmost and button six being the rightmost. EMS-D120
buttons are used to turn the instrument on and off, cycle
between screens, scroll through menus, and adjust
instrument parameters.
Display – The display shows engine parameters, menus, and
data obtained from other connected products.
User interaction takes place via the EMS-D120 main
display and the six buttons beneath. Note: buttons are
not labeled on actual product

Product Operation
Display
The EMS-D120 display is the most obvious and commonly used output of the device. It is capable of displaying EFIS,
HSI, and/or engine data simultaneously.
SCREENS AND PAGES
The terms in the following bulleted list are used in this section and are defined as follows:
Screen/Screen Configuration – Screens consist of one or
two pages from the EMS-D120 or from another DSABconnected Dynon Avionics product.
Page – A page is a section of the screen that contains a
collection of related data. Pages may occupy the total area
of the screen (i.e., 100%) or share the screen with other
pages (e.g., 2/3, 1/3 split). Pages that occupy 1/3 of the
screen area are sometimes abbreviated versions of their full
size (100% or 2/3) counterparts.
Screen Rotation – The rotation is the list of screen
configurations which can be cycled to via the hotkeys. Your
rotation is usually smaller than the total list of available
screen configurations.
Screens contain one or two pages and pages contain
groups of similar information.

right). Note that if you only press button six momentarily, the display
cycles to the next screen in your screen rotation. Use the
DOWN▼/UP▲ buttons to move the caret (>). The caret denotes the
selected screen. Press GOTO► to remove the SCREEN LIST and
display the selected screen. If you wish to stay on the same screen,
you may either select your currently displayed screen with the caret
and press GOTO►, or press CANCEL.
Screen Cycling Using Hotkeys
With no menu displayed, press button one to cycle to the previous
screen in your rotation. Likewise, press button six to cycle to the
next screen in your rotation (see the figure on the next page). Cycling
via hotkeys only allows you to display screens that are in your screen
rotation. They are meant to give you quick access to the screen
configurations that are most important to you. If you wish to access
