Questions & Answers

The sensor is not displaying zero force when I do not touch the mouthpiece.

The sensor needs a quick calibration. See the Calibration section for instructions.

The app displays the error message “The operation couldn’t be completed. (OSStatus error 561017449.)” when trying to connect to the sensor.

There is another app using the microphone, eg. a phone call. Stop all apps that are using the microphone and try again.
