  If the DeVilbiss Medical Equipment unit isn't operating, all lights are off, and an audible alert is pulsing, first ensure the power cord is properly inserted into the wall outlet. For 230-volt units, check the mains connection on the back. If it still doesn't work, check your home circuit breaker and reset it if needed. If problems persist, try a different wall outlet. Also, check the oxygen concentrator circuit breaker and reset it if necessary by pressing the reset button located below the power switch. If these steps don't resolve the issue, contact your DeVilbiss provider.

  If the red Service Required light is illuminated on your DeVilbiss Medical Equipment and an audible alert is sounding, check the following: * **Air filter:** If it's dirty, clean it according to the instructions. * **Exhaust area:** Ensure nothing is blocking the unit's exhaust. * **Cannula, mask, or tubing:** Detach these to see if proper flow returns. If it does, clean or replace the blocked component. * **Humidifier bottle:** Detach to check if flow improves; clean or replace if needed. * **Flow meter:** Ensure it's set to the prescribed rate. If issues persist, contact your DeVilbiss provider.
