What does the Zz function on my Philips SmartSleep Sleep & Wake-Up Light do?
The Zz function on your Wake-Up Light is the fall asleep or dusk stimulation function. Read here to find out how to use this option.
Fall asleep function
When you switch on the Zz function on your Wake-Up Light you set a timer in which the light gradually dims and then finally turns off. You can select a time frame from 5 to 60 minutes, depending on your preference.
To turn off this function, simply press the Zz button again. In the SmartSleep Sleep & Wake-up Light you can also tap the top of your light to deactivate the Zz function.
