Congratulations on your purchase and welcome to Philips! To fully benefit from the support that Philips offers, register your product at The Philips Wake-up Light helps you wake up more pleasantly. The light intensity of the lamp gradually increases to the set level in the 30 minutes before the set wake-up time. The light gently prepares your body for waking up at the set time. To make sure you will be woken up on time, a 'beep' sound will be played at the set alarm time.

The effects of the Wake-up Light

The Philips Wake-up Light gently prepares your body for waking up during the last half hour of sleep. In the early morning hours our eyes are more sensitive to light than when we are awake. During that period the relatively low light levels of a simulated natural sunrise prepare our body for waking up and getting alert. People who use the Wake-up Light wake up more easily, have a better overall mood in the morning and feel more energetic. Because the sensitivity to light differs per person, you can set the light intensity of your Wake-up Light to a level that matches your light sensitivity for an optimal start of the day.

This chapter summarizes the most common problems you could encounter with the appliance. If you are unable to solve the problem with the information below, visit or call 1-866-832-4361 for assistance.

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 connecting 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.
