Devilbiss OSD Operation
The OSD (Oxygen Sensing Device) is a device within your concentrator that monitors the oxygen produced by your unit. When the unit is turned "On," all four lights (Power,
Service Required, Low Oxygen, and Normal Oxygen) on the front panel will illuminate briefly. After a few seconds, only the Power and Normal Oxygen lights will remain lit.
The OSD lights on the front panel are defined as follows:
• Green Normal Oxygen light–acceptable oxygen level .
• Yellow Low Oxygen light– below an acceptable oxygen level .
If the oxygen purity falls below the acceptable level, the green Normal Oxygen light will shut off and the yellow Low Oxygen light will illuminate. Switch to your reserve oxygen
system . Refer to the Minor Troubleshooting section in this guide on page 7 and contact your DeVilbiss provider .
As an added safety feature should the oxygen purity continue to drop, an intermittent audible signal will sound. Contact your DeVilbiss provider immediately. Do not attempt
any other maintenance .

RESERvE OXygEN SySTEm

As a precaution, your DeVilbiss provider may supply you with a reserve oxygen system. If your unit loses electrical power or fails to operate correctly, the Patient Alert System
will sound to signal you to switch to your reserve oxygen system (if provided) and contact your DeVilbiss provider .
