Oxygen
This single person SBA oxygen delivery device is intended for
supplemental breathing while exposed to high altitudes. On
demand and up to 25 BPM, this device delivers a pulse of
supplied oxygen at the start of each inhalation phase. Higher
altitudes are automatically compensated with larger pulses.
AIRCRAFT PILOTS SHOULD REFER TO FAR 23.1447
CONSULT MANUAL FOR PROPER DEVICE USAGE
DEVICE WILL NOT OPERATE PROPERLY UNLESS SPECIFIED
CANNULAS, FACE MASKS & REGULATORS ARE USED

Page 3: How It Works
With new user selectable settings, total apnea alarm and smaller size the new EDS-D1 provides the same reliable operation that users of the EDS-A1 have come to rely upon and more. The EDS-D1 operates on known physiological facts that the breathing cycle of a healthy, non-smoking person is such that about one-third of the time is spent inhaling while two-thirds is spent exhaling and pausing. - Page 4 (fig 1.) This is best done if the unit is held with the battery door facing up at you and out. The EDS-D1 unit uses a standard 9 (nine) volt alkaline battery connector system. This is a very positive- connecting type connector that requires a bit more force to connect and disconnect to the battery.
- Page 5 The EDS-D1 has proven to be very reliable and has been used by many pilots for several years in various types of aviation. The EDS-D1 unit and has no means inside itself to provide a by pass of oxygen in the event of a total failure.
- Page 6 "Night" or "Now" mode The first power on setting advanced from off is the N for "Night" or "Now" setting. At this setting the EDS-D1 will respond to breathing actions at all altitudes with the standard delivery protocol. The EDS-D1 will deliver pulses of oxygen at the effective flow rate of 1.0 liter/min.
- Page 7 If the EDS-D1 unit is used with one of our standard regulators, such as our XCP, XCR, RCV/RCR the R/M setting is intended for times when you may desire to receive oxygen during the (near) full reserve inspiration cycle to manage possible acute dyspnea (shortness of breath) and/or anxiety while under stressful and/or demanding flying conditions.
- Page 8 Display Information There are two high brightness LEDs on the EDS model D1. The green LED indicates positive oxygen flow for every breath. The red LED indicates any flow fault or apnea conditions and blinks for low battery conditions. FLOW FAULT ALARM The EDS model D1 will produce an optical (red LED) and audible flow fault alarm from the following reasons: 1.
