12. Check that the forehead sensor band is positioned across your lower forehead, and
is not touching your eyebrows or hairline. There should be no hair between your skin
and the sensor. You can also put a dab of water on your forehead under the forehead
sensor to help it connect.
13. Turn on the device by pressing the power button for 1 second. This will enable the
start of your sleep session.
Note
Especially when seasons are changing, and the air tends to be dryer, it may be
more of a challenge to get your headband connected to use at night. Put a dab
of water on your forehead under the forehead sensor to help it connect.
Headband Set Up
After pushing the power button for 1 second, the headband will start to beep. The
headband will continue to beep, and the status indicator light will display a solid
orange light. This is indicating that you do not yet have a connection set up between the
headband and sensors. The headband should stop beeping before you to go sleep.
The headband may take 15-30 seconds to set up the connection to the sensors. If the
beeping does not stop and the indicator light does not turn green after this time, ensure
that there is no hair trapped between your skin and the sensors, and try putting a dab
of water on your forehead under the forehead sensor to help it connect. The headband
will continue trying to set up until you either make a connection with the sensors, run
out of battery, or turn it off. Consult the troubleshooting guide if you cannot set up the
headband.
Once your headband sets up successfully, it will stop beeping, and the status indicator
light will turn green. You are ready to sleep!
