GENERAL
- Do not use this appliance as a means to reduce your hours of sleep. The purpose of this appliance is to help you wake up more easily. It does not diminish your need for sleep.
- Consult your doctor before you start using the appliance if you have suffered from or are suffering from depression.
- If you often wake up too early or with a headache reduce the set light intensity level and/or the set sunrise simulation time.
- If you often wake up by the alarm sound, increase the set light intensity level or the set sunrise simulation time.
- If you share a bedroom with someone else, this person may unintentionally wake up from the light of the appliance, even though this person is further removed from the appliance.
This is the result of differences in light sensitivity between people.

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, the light intensity of the lamp gradually increases to the set level and 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.
Intended use
This Wake-Up Light allows you to choose the light intensity level you want to wake up to. This is not a general illumination product.
The effects of the Wake-Up Light
The Philips Wake-Up Light gently prepares your body for waking up during the last 30 minutes 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.
For more information about the Wake-Up Light, see www.philips.com.

Overview

Press the MENU button to enter the menu
Press the + or - button to select a menu setting
Press SELECT to confirm



Note:
To exit the menu, either press the MENU button or wait for 30 seconds.
First use: placing the Wake-Up Light
Place the Wake-Up Light 16 in. – 20 in. / 40 cm – 50 cm from your head, for example on a bedside table.
First use: setting the clock time
You have to set the clock time when you plug in the appliance for the first time and when the time back up has been exceeded (up to 8 hours).







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). For each profile, you can set the time, sunrise simulation (see Adjusting the sunrise simulation time) and the type of sound.
You can set two different wake-up profiles (alarms). For example if you want to wake up at a different time in the weekend than on weekdays.
To set the wake-up profile for alarm 1 or 2, select the corresponding alarm at step 2.
To activate or deactivate an alarm, press alarm button 1 or 2 on the appliance (see 'Overview').

12 English
Setting your wake-up sound
You can use natural sounds or the FM radio as a wake-up sound.
The Wake-Up Light has several 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.

When there has been a power failure, the set clock time will be saved for up to 8 hours. If the power failure lasts longer, the set clock time will be lost. You have to set the correct clock time again.
14 English
Setting the display brightness
You can adjust the display brightness from level 0 (off) to level 4. We advise you to set the display brightness in a dark bedroom. Choose a brightness level that is optimal for you to see the display at night. The display brightness 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.

Switching the lamp on/off
Press the lamp on/off button to switch on the lamp and use it as a bedside lamp. You can adjust the light intensity by pressing the + and - buttons. To switch off the lamp, press the lamp on/off button again.



Switching the FM radio on/off
Press the FM on/off button to switch on the FM radio.

Switching the alarm on/off
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'.
18 English
Snooze
When the wake-up curve has ended (when the set maximum light intensity has been reached) and the alarm sound is playing, you can tap the top of the appliance to snooze.
The lamp stays on, but the sound is muted. After 9 minutes, the alarm sound starts playing again.

Note:
The alarm 1 or alarm 2 icon flashes on the display when the alarm is snoozed. If you press either the FM button, the fall-asleep button or the MENU button while the alarm sound is playing, the alarm stops and is not snoozed. If you press the alarm button while the alarm sound is playing, you disable the alarm function. The alarm icon disappears from the display. To reactivate alarm function, press the alarm button again.
Fall-asleep
To use the fall-asleep function you need to select a timer.
1 Press the fall-asleep button to switch on the fall-asleep function. The fall-asleep time flashes on the display for a few seconds.
2 Press the + or - button to adjust the time (5 to 60 minutes). Press the SELECT button to confirm the timer setting.
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.
Adjusting the sunrise simulation time
The sunrise simulation time is the time in which the light intensity of the lamp gradually increases to the set level before the alarm sound is played. The default sunrise simulation time is 30 minutes, but you can reduce the sunrise simulation time to 20 or 25 minutes or increase it to 35 or 40 minutes.
1 Simultaneously press and hold alarm 1 and alarm 2.
2 The default sunrise simulation time of 30 minutes appears on the display.
3 Press the + and - button to adjust the minutes.




Demonstration mode
If you want a quick demonstration (90 seconds) of the gradually increasing light intensity and sound level, switch on the test function of the appliance.
1 Press and hold the alarm 1 or alarm 2 button for at least 3 seconds.
2 The appliance starts the demonstration of the corresponding alarm.
3 To switch off the demonstration, press and hold the previously pressed alarm button for 3 seconds again.
