Problem Solution
The appliance does not
respond when I try to
set different functions.
Remove the plug from the wall outlet and reinsert it. If you reinsert the
plug within approximately 15 minutes, the appliance remembers all
settings. If you reinsert the plug after a longer period of time, the
appliance will go back to factory settings. You need 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 by setting the control lever to the
top position. To switch on the alarm, set the control lever to the middle
position.
The lamp does not go
on right away when I
switch it on.
It takes approx. 1 second for the lamp to go on. This is normal, the
lamp needs to heat up.
I do not hear the alarm
sound when the alarm
goes off.
Perhaps you set a sound level that is too low. To set a higher sound
level, see chapter ‘Using the appliance’, section ‘Radio/volume’.
Perhaps you switched off the alarm by setting the control lever to the
top position.
Switch on the radio after you switch off the alarm to check if the radio
works. If it does not work, call 1-866-832-4361 for assistance.

The radio produces a
crackling sound.
Perhaps the broadcast signal is weak. Adjust the frequency (see chapter

position of the antenna by moving it around. Make sure you have
unwound the antenna completely.
The alarm went off
yesterday, but it did not
go off today.

top position.
Perhaps you set a sound level and/or light intensity level that is too low.
Set a higher sound and/or light intensity level.
Perhaps there was a power failure that lasted more than approximately
15 minutes. In this case the appliance goes back to factory settings. You
need to set all functions again.
The alarm did not go off
9 minutes after I pushed
the control lever down
to snooze.
Perhaps you pushed the control lever down with so much force that it
jumped to off position.
Perhaps you set the volume level to OFF.
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.

Problem Solution
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.
Perhaps the appliance is not suitable for the voltage to which it is
connected. Make sure that the voltage indicated on the appliance
corresponds to the local voltage.
