GETTING STARTED
The MH EDS O2D1 is intended to be used with regulators provided by Mountain High. Some third-party oxygen regulators may
be used. See “Using a Third-Party Regulator” page 6 for details. Pilots who intend to fly with the MH EDS O2D1 are advised to
familiarize themselves and their passengers with the system prior to using it. Two cannulas and a face mask are included with
the MH EDS O2D1 unit. The cannula may be used for flight operations up to 18,000 ft. Above 18,000 ft., a face mask should be
worn. A compatible face mask with a built-in microphone is available from Mountain High.

1. If
you have not already done so, fill your cylinder with
Aviation oxygen. (Many FBOs offer this service.)
2. Inventory
your system
(see photo) and
read the front
label on the unit.
3. Read
the instructions provided with your cylinder and regu
-
lator, attach the regulator to the cylinder and
hand tighten
only
(DO NOT use a wrench or pliers.
The “O” ring seals the regulator to the
cylinder, and over tightening will damage
the regulator).
4. Open
the battery cover on the back of the MH EDS-O2D1
unit, install the 2 AA batteries (supplied) and replace the
battery cover.
(NOTE: Batteries fit tightly, handle with
care.) See next page for detailed instructions.

If
you are using the MH EDS-O2D1 with a Mountain High
Four-Port regulator (FPR), locate the oxygen input tube (clear
tube with a short red tube on one end) and insert the
Red
tube into the red “Oxygen In” connector on the MH EDS-
O2D1 unit until it stops (approx. 1/8 inch). Then connect the
other end of the tube to your regulator. If you are using a MH
single port regulator (
XCR
), use the tube that came with the
regulator in place of the tube that came with your MH EDS-
O2D1.

Insert
the Blue end of the cannula or face mask tubing into
the
blue
“Out” connector on the unit.
(CAUTION: DO NOT pinch the Cannula or
Facemask tubing when inserting them
into the blue “Out” connectors). Use only
the supplied MH EDS cannula as other can-
nulas may not work properly with the MH
EDS-O2D1. DO NOT lengthen or shorten the
cannula tube.
7.
Turn
the cylinder valve on.
8.
Push
the “+” power/control button on the MH EDS-O2D1
unit once. This will turn the unit on and set it to “N” mode. A
start-up pulse of oxygen, LED light and beeper test will verify
battery power.
9.
Don
the cannula or face mask (make sure the face mask
seals against the skin) and take a breath. The bright green
LED should illuminate, and a pulse of oxygen should be
delivered. Refer to the card that comes with the cannula
or facemask for details on donning.

You are ready to fly
