  First, check the power cord connection at the wall outlet. For 230 volt units, verify the mains connection on the back of the unit. If that doesn't work, check your home circuit breaker and reset it if necessary. Try a different wall outlet. Also, check the oxygen concentrator circuit breaker and press the reset button located below the power switch. If the problem persists, contact your DeVilbiss provider.

  The yellow Low Oxygen light may be triggered if the flow meter isn't properly set; ensure it's set to the prescribed number. It could also indicate a blocked air filter, so check and clean it if necessary, following the cleaning instructions. Another possibility is a blocked exhaust area; make sure nothing is restricting the unit's exhaust. If the issue continues, contact your DeVilbiss provider.

  The red Service Required light may be on for several reasons. Check the air filter and clean it if it's dirty, following the cleaning instructions. Also, ensure nothing is blocking the exhaust area of the unit. Check the cannula, face mask, or oxygen tubing for blockages or defects; detach them to see if proper flow is restored, and clean or replace if needed. Inspect the humidifier bottle for blockages or defects, detaching and cleaning or replacing it if necessary. Finally, ensure the flow meter is set to the prescribed flow rate. If problems continue, contact your DeVilbiss provider.
