How do I keep my breath sensor and its mouthpiece clean?

Cleaning your breath sensor is optional.  If you do want to clean the sensor:

• Use a lightly damp clean cloth to wipe down the outside of the breath sensor.
• Do not allow water to enter any openings in the device, or submerge the breath sensor in water or other liquids.
• Do not use any alcohol-containing products, such as alcohol wipes or gel, on the breath. Alcohol-based cleaners may interfere with the function of your device.

Your breath sensor's mouthpiece is reusable and may be cleaned.  To clean:

• Remove the mouthpiece from the sensor
• Wash the mouthpiece with mild soap and water.
• Allow to completely dry before use.
• Reattach the mouthpiece to the sensor
