Problem
The sensor
data shows
incorrect
information.
Possible cause / solution
The battery was almost empty when you
started the sleep session. If the battery
runs out during a sleep session, the sensor
switches off and stops collecting data.
The sleep session lasted more than 12 hours
and automatically stopped (to save battery).
The display shows error code A2 (see 'Error
code'). The sleep session has exceeded the
maximum of 12 hours or was not stopped
properly. Make sure you manually stop a
session (see 'Stopping a sleep session').
Possible cause / solution
Within two hours of stopping a sleep
session, you started another sleep session.
If you start another sleep session within
two hours after switching off the previous
session, the sensor will register these two
sessions as one single session.
The sleep session was shorter than one
hour. The display shows no data for
response rate and hours on your back. It
shows 'A1' for sessions shorter than 1 hour
(see 'Error code').
