BASIC SAFETY
INTRODUCTION
The patented MH EDS-O2D2 is a one or two-user aviation oxygen delivery device. It is designed to deliver aviation oxygen in
the most efficient, comfortable and convenient way possible. With its user-selectable settings, apnea alarm and small size,
the MH EDS-O2D2 is the most portable and flexible electronic digital oxygen delivery system in the world.
By providing a measured pulse of oxygen every time you breathe in, the MH EDS-O2D2 supplies the oxygen you need to stay
alert and comfortable while flying. In contrast to constant flow systems that waste oxygen by supplying more than your body
can use, the MH EDS-O2D2 provides a short pulse of oxygen as you inhale, ensuring that your oxygen is used most efficiently.
Efficient oxygen delivery means you can fly further on a single oxygen refill or save space and weight with a smaller tank. It
also makes it more feasible to enjoy the advantages of oxygen while flying below the altitudes where oxygen is mandated--
that can mean fewer headaches, increased alertness, and feeling less exhausted when you reach your destination. Your actual
oxygen usage will be determined by your breathing rate and physiological needs at altitude.
The programmability of the MH EDS-O2D2 means that, unlike constant-flow oxygen systems, you can “set it and forget it”.
By automatically detecting your pressure altitude, the MH EDS-O2D2 can be set to start providing oxygen immediately or at
a specified altitude and will automatically adjust the oxygen flow as your altitude changes.
When you’re flying, don’t you
have more important things to do than adjust your oxygen flow during altitude changes?

Pure oxygen is a highly oxidizing gas and can vigorously accelerate combustion. It can provide a catalyst for spontaneous combus-
tion resulting in personal injury or death if not used properly and with caution.
DO NOT use any type of oil or grease on
any of the fittings, valves or cylinders. DO NOT smoke while in use. DO NOT operate near an open flame.
DO NOT use the MH EPS (External Power Supply) with the O2D2 as the voltages are not compatible.
