1. INTRODUCTION
Thank you for purchasing the Dynon Avionics EMS-D10. 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-D10 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
EMS-D10 Pilot’s User Guide 1-1
If your EMS-D10 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-D10 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, 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.

Introduction

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.
About this Guide
This guide serves two purposes. The first is to help you configure and get acquainted with the EMS-D10’s many
functions. The second is to give you quick access to vital information. For detailed technical and installation information,
please refer to the EMS-D10 Installation Guide.
In the electronic (.PDF) version of this manual, page and section references in the Table of Contents and elsewhere act as
hyperlinks taking you to the relevant location in the manual. The latest version of this manual may be downloaded from
our website at www.dynonavionics.com.
The following icons are used in this guide:
Any text following this icon describes functionality available only with the HS34 HSI Expansion Module
connected to your system.
Any text following this icon describes functionality that is possible when multiple Dynon Avionics products are
networked together via the Dynon Smart Avionics Bus (DSAB).

2. PRODUCT OVERVIEW
This EMS-D10 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-D10 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-D10 Hardware
The EMS-D10’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-D10 requires between 10 and 30 volts DC for operation. It is acceptable to have the EMS-D10 turned on
during engine start.
SENSORS AND INPUTS
EMS-D10 Pilot’s User Guide 2-1
When connected to the appropriate sensors, the EMS-D10 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
2-2 EMS-D10 Pilot’s User Guide
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-D10 has outputs to drive external customer-supplied audible and visual devices for engine, AOA (if installed)
and altitude alerts.
A connected HS34 can output voice annunciations for many of the alerts generated by the EMS-D10.
DISPLAY
The display is a 4-inch, 320 by 240 pixel, 450-nit LCD screen.
BUTTONS
User interaction takes place via the six buttons along the bottom of the front panel of the unit.

EMS-D10 Pilot’s User Guide 3-1
User interaction takes place via the EMS-D120 main
display and the six buttons beneath. Note: buttons are

3. PRODUCT OPERATION
After reading this section, you will be familiar with the basics of how to use your EMS-D10. 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-D10 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-
D10. 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-D10 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.

Product Operation
3-2 EMS-D10 Pilot’s User Guide
Screens contain one or two pages and pages
contain groups of similar information.
Display
The EMS-D10 display is the most obvious and commonly used output of the device. It displays all EMS-related data
and, when connected to other data sources, can display EFIS and HSI data as well.
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-D10 or from another DSAB-connected 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 (i.e., 1/2 split).
•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.

Product Operation
The EMS-D10 has several pre-defined screen configurations. The
basic layout of a screen configuration is represented by one of two
icons on D10-series product. The table below shows the two icons
and their meaning.
Icon Left Page Area Right Page Area

3-4 EMS-D10 Pilot’s User Guide
With no menus displayed, pressing button six
for two seconds displays the SCREEN LIST
menu, from which you may switch to, and set
up, various screen configurations.
CYCLING BETWEEN SCREENS
There are two methods for cycling between pre-defined screens: via the
menu and via hotkeys.
Screen Cycling Using the SCREEN LIST
Navigate to the SCREEN LIST menu by holding button six for at least
two seconds when no menu is present (see the figure to the 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 screens that are not in your
rotation, use the SCREEN LIST as described above.
Hold for two seconds

Changing the Screen Rotation
You may use the out-of-the-box screen rotation or define your own. If you desire to use the initial rotation, no user
configuration is required. If you desire to use a custom cycling order, then user configuration is necessary.
To configure a custom rotation, navigate to the SCREEN LIST menu
page by pressing button six for approximately two seconds when no
menu is present. Press SETUP, then press ROTATN to display the
menu used to change the boot and rotation screen. Scroll through the
pre-defined screens using the DOWN▼/UP▲buttons.
Press the BOOT* button on any selected screen configuration to make i
the screen that is shown immediately after the instrument is turned on.
Only one screen may be designated as the boot screen. Next, press the
TOGGL↕button on any selected screen to toggle the “↕” icon. All
screens that show the “↕” icon are included in the rotation. Any screen
in the rotation may be accessed via the button one and six hotkeys.
Press BACK to save any settings.

Menus
All interaction with the EMS-D10 is accomplished through the use of its menu system. The
menu system is accessed and navigated via the six buttons located on the front of the unit.
PAGE-SENSITIVE MENUS
On a screen where no menu is already present, buttons two through five are used to display a
menu. With no menu displayed, pressing any one of these buttons causes the menu for the
page above it to show at the bottom of the screen. For example, if a screen is divided into two
pages with the left page occupying 1/2 of the screen and the right page occupying 1/2 of the
screen, then pressing EMS-D10 buttons two or three (all below the left 1/2 of the screen)
displays the main menu for the left page and pressing buttons four or five (below the right 1/2
of the screen) displays the main menu for the right page (see the figure to the right).
FUNCTIONALITY
A menu consists of two rows of gray boxes containing text. The upper row contains one tab
that denotes the currently displayed menu. The lower row contains six labels that denote the
function of the button below it. Many of the onscreen elements move up to avoid the menu.
This prevents the menu from obscuring useful data while it is up. Upon exiting the menu, the
screen returns to its normal appearance.
Pressing a button either displays another menu or adjusts a parameter. If there is no text above
a button, then that button does not have a function in the context of that menu. Occasionally, a
button label spans two or more buttons. In this case, any button below the label invokes the
command.
The configuration of the
pages on the screen
determines which
buttons are used to
display a page's menu.

Product Operation
EMS-D10 Pilot’s User Guide 3-7
If a menu contains more options than there are buttons, the MORE label is displayed over button five. Pressing this
button shows you the next set of options in the current menu.
In any menu, press the BACK button to return to the previous menu and save any changes. In all top-level menus, button
six is the EXIT button. Pressing EXIT removes the menu system and moves many of the onscreen elements down to
their original positions.
FLOW
Each page has its own main menu, which may contain options for
navigating to other menus or choosing and adjusting parameters.
For example, the EMS Main Page menu contains an EMS menu tab
and button labels for LEAN, AUX, FUEL, MORE, and EXIT.
Pressing MORE reveals the rest of the EMS menu. The continuation
of this menu contains options for LISTS, SETUP, DIM, TIMES,
MORE, and EXIT. Pressing MORE on this menu simply returns you
to the first part of the EMS menu.
In all top-level split-screen menus (TIMES/AUX only), the leftmost
button is the MENU button. If you have opened up the left page’s menu, the label reads MENU ►. Pressing the button
switches the menu to display the right page’s menu, and the label switches to read ◄MENU. The arrow on this button
always points to the side of the screen whose menu will be displayed when pressing the button.
All EMS pages (AUX, TIMES, FUEL) have shortcuts to their page and menu from within the EMS Main Page menu.
This means that if you only want to glance at a parameter on another page, quickly returning to your original screen
configuration, simply enter the EMS menu, and press the button for the page you’d like to momentarily view. For
example, if your current screen configuration is full EMS pressing the AUX button in the EMS menu will display the

AUX page in place of the EMS page. Pressing BACK will return you to the main EMS menu, and your original screen
configuration (i.e., EMS).
If you press the SETUP button on the EMS
menu, the SETUP menu is displayed. The
SETUP menu contains a menu tab and button
labels for CLOCK, VRSION, GLOBAL,
SENSOR, FUEL, and BACK. Pressing CLOCK
displays options for specifying time format (i.e.,
standard AM/PM vs. military) and clock
adjustment.
In any menu with more options than will fit on a line, the MORE button
displays the rest of the menu.
To exit the menu system, press the BACK button as many times as is needed to reach an EXIT button. This varies based
upon how deep you are into the menu system.
DESCRIPTIONS IN THIS GUIDE
3-8 EMS-D10 Pilot’s User Guide
Throughout this guide, the “>” character is used to indicate entering a deeper level of the menu system. For example,
“EMS > SETUP > CLOCK” indicates entering the EMS menu, pressing MORE, then pressing SETUP, and then
pressing CLOCK to enter the clock adjustment menu. Note that the MORE button is not included in the sequence, since
pressing MORE reveals more options in the same level of the menu system.
