Insert the batteries as shown on the label inside the battery compartment (they will be a tight fit), then replace the door by slid- ing the door into place until it snaps in place. -
Page 5: And Modes Of Operation
The F-Mode settings augment the amount of oxygen needed to compensate for the additional dead-space plenum associated with face masks. They also can be used with the MH cannula in situations where more oxygen may be required over the normal ‘N’ and ‘D’ set- tings. -
Page 6: Alarms And Alerts
Time before Apnea event is ~30 ~35 seconds. This typically occurs for the following reasons: (1) The user has quit breathing for 30 - 45 seconds or the cannula/face mask is improperly worn. (2) The outlet tube from the MH EDS- O2D1 to the mask or cannula has become disconnected. -

Page 8: Maintenance Questions
Portable Systems: ™ I have one of your portable MH-EDS PULSE DEMAND™ units. It seems to be operating just fine, should I send it in for any type of routine service or testing? Yes. Even though your pulse-demand unit will generally let you know if there is a problem and has been designed to be relatively maintenance free except for batteries, it should be sent in on a regular basis for performance inspection and service. -
Page 9: What Every Pilot Should Know About Oxygen
WHAT EVERY PILOT SHOULD KNOW ABOUT OXYGEN What Is Air? The air surrounding us is a mixture of gases consisting of 78% nitrogen and 21% oxygen. The remaining 1% is made up of argon, carbon dioxide, and traces of rare gases. What Is Oxygen? Under normal conditions, pure oxygen is a colorless, tasteless, odorless, non-combustible gas. - Page 10 How Should An Oxygen System Or Equipment Be Selected? Your MH Sales Engineer can help you at 800-468-8185. He or she can assist the pilot in selecting the system best suited to the specific airplane and the pilot’s special needs.

Page 11: Auto Compensation
AUTO COMPENSATION INFORMATION EDS O2D1-2G Auto-compensation Altitude compensated breathing sensor Because absolute atmospheric pressure lessens as a function of altitude, breathing efforts assert less pressure upon breath- ing sensors to the point at which they may not properly detect breathing while at higher altitudes. Additionally, as the partial pressure of CO2 drops below a normalized point with altitude, one’s breathing efforts also diminish. -
