ALERT SYSTEM
The DeVilbiss iFill Personal Oxygen Station alert system will
detect unit component failure. This system is comprised of both
visible and audible alerts which signal the patient if a
malfunction should occur.
The visible alert located on the top indicator light panel reads
“Service.” When the red indicator light illuminates and the
audible alert sounds a problem has occurred and service is
required. Refer to the Troubleshooting section of this manual.
