Page 3: Safety Notes
SAFETY NOTES WARNING: INDICATION FOR USE: This device designed to extract oxygen from atmospheric air. It will typically be an electrically-powered molecular sieve (artificial zeolite) used to separate nitrogen from room air. The oxygen concentration is variable, depending on the flow rate being utilized. - Page 4 SAFETY NOTES Be certain to place the device so all sides are at least 10 cm (4 inches) away from walls, draperies, furniture, or other obstruction. MUST place the oxygen concentrator in a well-ventilated area. Always place the device in the expected position that the operator can hear the audio alarming.
- Page 5 SAFETY NOTES Ⅵ. RADIO FREQUENCY INTERFERENCE This equipment generates, uses and can radiate radio frequency energy and, if not installed according with the instructions, may cause harmful interference to other devices in the vicinity. However, there is no guarantee that interference will not occur in a particular installation.
