Frequently Asked Questions

If the mouthpiece is not all the way in, or if it hasn’t been inserted correctly, the air ports may not be properly aligned. This could result in a “tamper detect” message. You may also receive that message if you are blowing compressed air instead of your own, or if you are blocking the exhaust port on the back of the device. Additionally, if you blow too much moisture during a test, you will get this error. You should rinse out your mouth before each test, but make sure to swallow any lingering moisture or saliva before testing.
