Problem Solution
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.
Perhaps the appliance is defective. Call 1-866-832-4361 for assistance.
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.
If you selected the radio as the alarm sound, the radio may be
defective. 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 does not
work.
The radio may be defective. Call 1-866-832-4361 for assistance.
The radio produces a
crackling sound.
Perhaps the broadcast signal is weak. Move the middle dial up or down
to adjust the frequency and/or change the 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.
Perhaps you switched off the alarm by setting the control lever to the
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 has remembered all settings
except the clock time. The clock time therefore ashes on the display.
Set the correct clock time.
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 0 (shown on the display as ‘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.
