Light intensity of the wake-up profile
The lamp of the Sleep & Wake-Up Light simulates a sunrise. Like a sunrise,
the brightness of the lamp increases gradually. During this wake-up curve,
the colors of the light changes from soft red to warm orange to bright yellow.
You can choose one of the 25 light intensity levels.
Note: The main display of the Sleep & Wake-Up Light shows if the alarm has
been set.
Type of sound
You can choose between three options. Select one of the natural sounds, no
sound or the FM radio.*
*HF3653 does not feature a radio.
PowerBackUp+
In the event of a power failure, all functions of the Sleep & Wake-up Light,
including the display, do not work. However, the internal clock and a back-
up alarm remain active for at least 8 more hours.
If during the power failure the set alarm time is due, a back-up alarm goes
off generating a beeping sound for approximately 1 minute.
Snoozing
When the wake-up curve has ended (e.g. the set maximum light intensity is
reached) and the alarm sound is playing, you can tap the top of the Sleep &
Wake-Up Light to snooze.
The lamp stays on, but the sound is muted. After 9 minutes, the alarm sound
starts playing again.
Note: The device automatically switches off (light and sound) 60 minutes
after the alarm time or 60 minutes after the last snooze action.
Turning the alarm off
When the alarm goes off, you can turn off the alarm by pressing this button.
If you turn off the alarm, the alarm profile is deactivated for that day.
