Page 2: Introduction
In contrast to constant flow systems that waste oxygen by supplying more than your body can use, the MH EDS-O2D1 provides a short pulse of oxygen as you inhale, ensuring that your oxygen is used most efficiently.

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.

MOUNTING THE MH EDS-O2D1 You may mount the MH EDS-O2D1 unit to a suitable place using the supplied piece of 3M DUAL LOCK tape. Peel the protective backing off one of the rectangles to expose the adhesive and apply it to the back of the unit above the thumb indent for the bat- tery door.
Page 5: Mode Control Switch Settings And Modes Of Operation
Altitude Compensating?: Yes D MODES: “Day” or “Delayed” The D5 setting will cause the MH EDS-O2D2 unit to delay oxygen flow until it senses a pressure altitude of 5,000 ft. and above. The D10 setting delays oxygen flow until 10,000 ft. and above. NOTE: When the barometric pressure is low, it will start operation at a slightly lower altitude than when the barometric pressure is high.
Page 6: Alarms And Alerts
NOTE: The FLOW-FAULT is not intended as a low or out-of-oxygen warning. It is only intended to warn the pilot that there is no oxygen flowing to the EDS O2D1 unit. This typically means that the cylinder valve was not opened, or the supply line has been pinched closed, or is plugged up, or has come off, or the valve in the O2D1 has failed to open.
