User manual PHILIPS HF3550

[. . . ] Wake-up App: Content of Help pages 1. The Wake-up Light uses a unique combination of light and sound to wake you in a gentle way, so you are ready for the day ahead. This app is compatible with the Philips Wake-up Light HF3550. Wake up Wake up naturally The Wake-up Light wakes you in a natural way, by using light that increases gradually and simulates the sunrise. [. . . ] It typically takes a few days to first get used to the Wake-up Light and then find your preferred settings. If you need additional reassurance, you can set a backup alarm in this app with a louder volume. For example, set your main alarm for 7:00 with light and sound, and a backup alarm at 7:30 with sound only. The backup alarm will ring even during a snooze period. 2f. Which Apple products can I use in combination with the Wake-up Light?You can use iPhone 3GS and above, or iPod touch 3 and above. Make sure that you at least have iOS5 installed. Does the Wake-up Light work without an iPhone/iPod?No, The Wake-up Light only works in combination with an iPhone or iPod touch. Without an iPhone/iPod touch you can only use the Wake-up Light as a normal lamp. Sometimes I get a message: "Wake-up Light would like to communicate with the Philips wakeuplight; allow - ignore". This means that the Wake-up Light wants to communicate with your iPhone/iPod. Please choose allow, to be able to control the Wake-up Light with the app. If you choose 'ignore', the app will not start. The app does not always start when I dock my iPhone/iPod. You can undock your device and dock it again, or open the app manually on your iPhone/iPod after docking your device. You can tap anywhere on the Wake-up Light itself, or press 'snooze' in the app. There are several ways: 1: you can switch off the alarm sound by choosing 'Stop alarm' in the app. 2: you can switch off the alarm sound by pressing the sound on/off button on the Wake-up Light. 3: you can switch off the alarm sound by undocking your iPhone/iPod. Note: in all cases the light will remain on. The iPhone/iPod screen emits a lot of light, even in the dark (Sleep Well) screen. [. . . ] This is the case during the day and during the night. In the morning, when the eyes are still adapted to darkness, relatively moderate light intensities (such as the ones of the Wake-up Light) can be sufficient to activate the body and reduce sleepiness. During the day one needs to seek much brighter light to increase alertness, such as the light provided by the sun or Philips light therapy devices. In the case of the Wake-up Light, the gradual increase of light intensity before awakening gently prepares the body for waking up and has the additional effect of reducing sleepiness. [. . . ]
