Question Answer
Perhaps you switched off the alarm function by pressing the ALARM
button.
Perhaps the lamp is defective. Replace the lamp (see chapter
‘Replacement’).
Why can I not switch on
the lamp again
immediately after I
switched it off?
You have to wait 3 seconds for the lamp to dim. During this time, the
3 button does not work.
Why do I hear no sound
when the alarm goes
off?
Perhaps you set the sound level too low. Turn the volume control to a
higher sound level.
Perhaps you switched off the alarm function by pressing the ALARM
button.
If you selected the radio as alarm sound (HF3462/HF3461 only), the
radio may be defective. Press the radio button after you switch off the
alarm to check if the radio works. If it does not work, contact the
Philips Customer Care Centre in your country.
Why does the radio
(HF3462, HF3461
only) not work?
The radio function is probably defective. Contact the Philips Customer
Care Centre in your country.
Connect the external antenna if you have not yet connected it. See
section ‘Radio’ in chapter ‘Using the appliance’.
Why does the radio
(HF3462, HF3461
only) produce a
crackling sound?
Perhaps the broadcast signal is weak. Search for the correct signal (see
chapter ‘Using the appliance’).
The alarm went off
yesterday. Why did it not
go off today?
Perhaps you switched off the alarm function by pressing the ALARM
button. Set the alarm for the next day and switch off the wake-up
alarm sound and light the next day by pressing the
3 button (see
chapter ‘Using the appliance’).
Perhaps you set the sound and/or light level to a too low setting. Set a
higher sound and/or light level.
Perhaps there has been a power failure that outlasted the capacity of
the backup system. After a long power failure, the display shows an
incorrect clock time and the alarm time is 00.00. Set the correct clock
time (see chapter ‘Preparing for use’) and the correct alarm time (see
chapter ‘Using the appliance’).
Why does the light
wake me too early/too
late?
Perhaps the light level you have set is not appropriate for you. Try a
lower light level if you wake up too early or a higher light level if you
wake up too late. For most people, the light is effective at settings 9-20
(HF3451) or 7-15 (HF3462/HF3461).
Perhaps you woke up too late because the appliance is at a lower level
than your head. Make sure the appliance is located at such a height
that the light is not blocked by your bed, duvet or pillow.
