Why don't I hear the alarm sound when the alarm goes off?
Answer
Perhaps you set the sound level too low. Increase the sound level.
Perhaps you switched off the alarm function by setting the control lever to the top position.
If you selected the radio as the alarm sound, 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 Consumer Care Center in your country.
