Solution
Perhaps the light intensity you have set is too low. Select a higher light
intensity. Perhaps the appliance is positioned at a lower level than your head.
Make sure the appliance is located at a height at which the light is not blocked
by your bed, comforter, blanket or pillow. Also make sure the appliance is not
placed too far away.
Make sure you tap on the correct position (top/back) of the appliance.
The USB connection is only for charging your mobile phone. You are not able to
stream music to the Sleep & Wake-Up Light.
Try to set the volume on your mobile phone either higher or lower. If necessary,
adjust the volume level on the appliance as well.
The backup alarm went off. The internal clock and the back-up alarm remain
active for at least 8 hours. If an alarm is due during this back-up period, it will
go off. The alarm sound stops automatically after approximately 30 seconds.
You also can stop the alarm sound immediately by connecting the appliance to
the power briefly.
To prevent the back-up alarm from going off when the power is disconnected
(e.g. during storage), disable the alarms before you disconnect the appliance
from the power.
