Symptom:
Error 396 is being displayed on the PM5.
Resolution:
This error indicates an issue with the Bluetooth connection.
This can happen if the mobile device goes out of range from the PM5, if the mobile device is paired wirelessly to multiple devices such as Bluetooth speakers, or if the user is trying to run more than one fitness app to record the workout from the PM5 monitor.
Make sure you choose only one app to record the workout and close any others that could be running in the background. ErgData is a good app to choose to record and upload your Concept2 workouts.
