Perform a quick inspection of your device and equipment to ensure everything is in working order and set up properly, including the following steps:
- Make sure the plugs to the electrical outlet and to the machine are firmly in place.
- Check your electrical outlet to make sure it is working. (Is there a light switch controlling the outlet)?
- Examine the power cord for any visible signs of wear, fraying, or damage. Ensure the connection between the cord and the unit is secure.
- Make sure your tubing is properly connected to the machine.
- If your machine has a humidifier, make sure the water chamber is filled and the top is closed.
