GETTING STARTED
The
O2D2 is designed to be used with MH Cylinder Pressure Regulators. Pilots who intend to fly with the O2D2 are advised
to familiarize themselves and their passenger with the system prior to using it. Four cannulas and two face masks are included
with the O2D2 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 (AMSKM-2100-02) is available from MH.

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. Per
the instructions provided with your cylinder and pressure
regulator, attach the pressure regulator to the cylinder and
hand tighten only.
(DO NOT use a wrench or pli-
ers—the “O” ring seals the regulator to the
cylinder. Over-tightening will damage the
pressure regulator).
NOTE:
Pressure in the pressure regulator must be
released before the pressure regulator can be
removed from the cylinder.
4. Open
the battery cover on the back of the O2D2 unit, install
the 3 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 O2D2 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 O2D2 unit until it stops.
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 O2D2.

.
Insert
the
Blue
end of the cannula or face mask tubing into
the
BLUE
#1 Pilot “Out”
connector on the unit (see page 4).
Always use the #1 connector when only one (1) person
will be using the system.
For a second user, insert the
BLUE end of the cannula or face mask tubing into the
BLUE #2 connector.
The User #2 connection becomes active
when inhalation is detected after a short period of inhalations.
CAUTION:
DO NOT pinch the Cannula or Face Mask
tubing when inserting them into the BLUE “Out”
connectors)
. Use only the supplied MH EDS can-
nula as other cannulas may not work properly
with the MH EDS O2D2-2G. DO NOT lengthen
or shorten the cannula tube.
7.
Turn
the cylinder valve on.
8.
Rotate Mode-Selector Switch
on the O2D2 unit once. This
will turn the unit on and set it to “N” mode. A start-up pulse of
oxygen, Red 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 under the #1 should illuminate, and a pulse of
oxygen should be delivered.
Refer to the card that comes
with the cannula and face mask for donning information.
10.
Test
the O2D2 unit on the ground for proper operation and
adequate cylinder pressure. You are ready to fly.
