Frequently asked questions

The UBOX 400R is rechargeable. How long does it play for on a full charge?
The length of time a rechargeable radio plays for on a full charge can never be given precisely as it depends on a number of factors, including the type of music played (e.g. music with more bass requires more power), the volume selected (the higher the volume, the more power used), the ambient temperature (a battery produces less power in low temperatures), the age of the rechargeable batteries, etc.

The UBOX 400R plays for up to approximately 1 working day on a full charge (at an average volume level, at room temperature – depending on radio reception and music type).

The UBOX 400R only recharges when switched off. Why is this?
In order to prevent the charging process from having a negative effect on the quality of radio reception and music performance it was decided to separate charging and playing in a number of models.

Sometimes if I move my DAB+ radio even just 50 cm indoors I have better reception.
With DAB+ signal reception, moving the radio a short distance, even just a few dozen centimetres, can make a huge difference to the signal level. This is typical of DAB+ radio reception.

If I use my rechargeable drill near the radio the latter fades away. When I stop the sound returns. How come?  
If machines (e.g. drills, saw benches, forklift trucks, etc.) or battery chargers are operated next to or near a jobsite radio, the electromagnetic field they generate can interfere with reception by the jobsite radio. In the case of DAB+ reception, strong electric currents in the immediate vicinity can even cause the radio signal to fade completely.

How far away can you be without being disconnected from Bluetooth?
An average of 10 metres or more in open spaces. But this greatly depends on the type of mobile phone (the strength of the Bluetooth signal emitted by this telephone) and the presence of any intervening walls and doors. If you become disconnected from Bluetooth when leaving for a moment, as soon as you return within range connection will be restored automatically.

How do I connect my mobile phone to the UBOX 400R radio when doing so for the first time?
Simply via your mobile phone’s Bluetooth menu. Select "UBOX 400R” in your mobile phone’s Bluetooth menu. No PIN codes or similar are required

Can someone else connect to my radio via Bluetooth with their mobile phone at the same time?
No. Once it is connected the radio only recognizes your mobile phone. Only if you purposefully disconnect in the radio’s Bluetooth menu can another mobile phone be connected to it.

Can I also play internet radio or Spotify via the UBOX 400R radio?
Yes, this is possible, no problem.
