Introduction
Congratulations on your purchase and welcome to Philips! To fully benefit from the support that Philips offers, register your product at www.philips.com/welcome.
The Philips Wake-up Light helps you wake up more pleasantly. In the set sunrise simulation time (default is 30 minutes), the light intensity of the lamp gradually increases to the set levelland the light color changes from deep morning red to bright daylight. The light gently prepares your body for waking up at the set time. To make waking up an even more pleasant experience, you can use natural wake-up sounds or the FM radio to wake up to.
The effects of the Wake-up Light
The Philips Wake-up Light gently prepares your body for waking up during the last 20 to 40 minutes of sleep, depending on the sunrise simulation time you set. 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.

First use
Placing the Wake-up light

Place the Wake-up Light 16-20in/40-50cm from your head, for example, on a bedside table.
Setting the clock time
You have to set the clock time when you plug in the appliance for the first time and when there has been a power failure.

Menu
Setting your wake-up profile
When you set your wake-up profile, you set the wake-up time (steps 1 – 6), the light intensity (steps 7 and 8), and the sound level (steps 9 and 10) you want to wake up to. You can set two different wake-up times, for example, if you want to wake up at a different time on the weekend than on weekdays. The procedure to set the wake-up profile and wake-up sound is the same for both.

Setting your wake-up sound
You can use natural wake-up sounds or the FM radio as a wake-up sound. The Wake-up Light has five built-in natural sounds.

Adjusting the clock time
To set the clock time, choose between a 12-hour and a 24-hour clock and then adjust the time.

Setting the display contrast
You can adjust the display contrast from level 0 (off) to level 4. We advise you to set the display contrast in a dark bedroom. Choose a contrast level that is optimal for you to see the display at night. The display contrast will increase to a higher level when the Wake-up light measures a lot of light in the bedroom. This happens automatically, so you will always be able to see the display, even when the surroundings are lighter.
Note: If you choose level 0 (display off), you can see the display again by touching it.

Buttons

Press alarm 1 or alarm 2 if you want to switch the alarm on or off. The corresponding icon appears on the display when you switch on the alarm. It disappears when you switch off the alarm. When you switch on the alarm, the hour indication starts to flash. If necessary, you can now adjust the alarm time.

Note: If you want to adjust the light level or volume to wake up to, you have to use the menu. See chapter ‘Setting your wake-up profile’.
Snooze
When the alarm sound is played at the set time, you can tap on the front of the Wake-up Light to snooze for a while. The lamp stays on, but the alarm sound stops. After 9 minutes, the alarm sound is automatically played again. Do not hit the Wake-up Light with too much force, as this may cause damage.

Note: The alarm 1 or alarm 2 icon flashes on the display when the alarm is snoozed.
Fall-asleep
To use the fall-asleep function, you need to select a timer.
- Press the fall-asleep button to switch on the fall-asleep function. The fall-asleep time flashes on the display for a few seconds.

Note: You can listen to the FM radio during the fall-asleep function. Turn on the radio and select your favorite station. Then press the fall-asleep button to activate the fall-asleep function. The sound of the radio will gradually fade during the set fall-asleep time. If you turn on the radio after activating the fall-asleep function, the sound does not fade when the light dims. The sound will stop when the light goes out.
To switch off the fall-asleep function, press the fall-asleep button again. The fall-asleep icon disappears from the display.

Note: If you press the fall-asleep button without setting the time, the lamp goes on and then dims gradually over 30 minutes.
Extra Options
Adjusting the dawn duration time
The dawn duration time is the time during which the light intensity of the lamp gradually increases to the set level before the alarm sound is played. The default dawn duration time is 30 minutes, but you can reduce the dawn duration time to 20 or 25 minutes or increase it to 40 minutes.
- Simultaneously press and hold alarm 1 and alarm 2.
- The default dawn duration time of 30 minutes appears on the display.

- The appliance starts the demonstration of the corresponding alarm.
- To switch off the demonstration, press and hold the previously pressed alarm button for 3 seconds again.

You hear one click as a confirmation. To activate, press and hold the FM button again. You hear two clicks to confirm that the audio feedback is activated.
