will be a brief delay before the concentrator starts. The
alarm system emits a tone of one second duration, the
word HELLO appears on the hour meter LED panel, and
the green power indicator light illuminates.

system performs a self test, and emits a brief tone. If
the alarm does anything other than emit a brief tone,
see Section 6, Troubleshooting Guide, and follow the
appropriate steps.

your physician or therapist.
Note: To properly read the flowmeter, locate the prescribed
flowrate line on the flowmeter.

to the appropriate line.

Damage: If the flowrate on the flowmeter ever falls below
0.5L/min, check tubing or accessories for blocked or
kinked tubing or for a defective humidifier bottle.
If using a humidier bottle, the oxygen comes from the
humidier bottle outlet.
5. Connect the oxygen tubing barb connector securely to
the humidier outlet; the other end of the oxygen tub-
ing is used by the patient.
Note: Oxygenation times and the flowrate ranges are
established and prescribed by your physician.
