Problem Possible cause / solution
I'm lying on
my back, but
the sensor
does not
vibrate. When the adaptation phase is active
(session 1-7), it may take longer than 30
minutes before the sensor vibrates. The
sensor slowly builds up the number of
vibrations each night. During this phase the
sensor will not vibrate every time you sleep
on your back (see 'Adaptation phase').
Check if a dot is shown on the display,
indicating the active adaptation phase
active (see 'Adaptation phase'). From the
eighth session onwards, the sensor always
encourages you to turn from your back to
your side.
The sensor is switched off or the sleep
session is not active.
Start a session when when the sensor is
off or if you are in one of the data screens.
Press and hold the activation button for two
seconds. The sensor vibrates briefly and
shows '- -' on the display to indicate that
the sleep session has started (see 'Starting a
sleep session').
