## Questions & Answers

**Q: With the hf3531 model, the supplied usb port is- it able to support music play back? or is it just for charging. thank you**
A: Hi there, good question. That USB-port indeed is for charging only. Hope this answers your question! Kind regards, Remco

**Q: Does the alarm stay set for the following day after you've stopped it in the morning, and if so, what do you press to make this happen?**
A: The alarm always stays set. You can choose which days of the week you want to set it for. Like a mobile phone ⏰ 👍

**Q: Just received this. Is it normal for the light to reach the full preset intensity within 1-2 minutes after the alarm starts?**
A: Yes. The light starts to come on 25 mins before the alarm goes off. It starts with a deep dark red and very gradually gets lighter over the 25 mins

**Q: Does the time stay illuminated all night?**
A: No, it does not. I can confirm that you can set the illumination setting to "0", which will turn off the display whenever you are not touching the device.
