Caution! Prevent damage to your hearing!
If this headset is used with other devices, very loud acoustic signals/signal
events may result in hearing damage (acoustic shock). With other devices
there is no guaranteed acoustic protection against loud noises. Only use
this headset in conjunction with D3 mobile!
If you use the headset for extended periods, you should set the volume to a
moderate level. Over time, high volume levels can lead to hearing damage.
