Troubleshooting
Problem Solution
The appliance does not
work at all.
Perhaps the adapter is not inserted properly in the wall outlet. Put the
adapter properly in the wall outlet.
Perhaps there is a power failure. Check if the power supply works by con-
necting another appliance.
The appliance does not
respond when I try to set
different functions.
Remove the adapter from the wall outlet and wait a few minutes before
you reinsert it. When you reinsert the adapter, the appliance goes back to
the factory settings and you have to set all functions again.
The lamp does not go on
when the alarm goes off.
Perhaps you set a light intensity level that is too low. Increase the light
intensity level.
Perhaps you switched off the alarm function. The alarm icon is visible on
the display when the alarm function is active.
I do not hear the alarm
sound when the alarm
goes off.
Perhaps you switched off the alarm function. The alarm icon is visible on
the display when the alarm function is active.
The alarm went off
yesterday, but it did not go
off today.
Perhaps you switched off the alarm function.The alarm icon is visible on
the display when the alarm function is active. If you do not see the alarm
icon on the display, press the alarm button once (see ‘Setting the alarm’
section).
Perhaps you set light intensity level that is too low. Set a higher light
intensity level.
Perhaps there was a power failure that lasted more than a few minutes.
In this case, the appliance goes back to factory settings. You need to set all
functions again.
The light wakes me too
early.
Perhaps the light intensity level you have set is not appropriate for you. Try
a lower light intensity level if you wake up too early. If light intensity 1 is not
low enough, move the appliance further away from the bed.
The light wakes me too
late
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.
