Troubleshooting
No connection to phone or other device
• Before you can use your Stereo Bluetooth Headset
with your phone or other device it has to be added
once according to page 8.
• It is recommended to first add the headset to your
phone, in singlepoint mode. Select singlepoint mode
and add the headset to the phone again. In
multipoint mode, the phone or other device that first
adds the headset will be used for phone calls.
• Make sure the headset is charged and within range
of the phone or other device. We recommend a
maximum distance of 10 metres, with no solid
objects in between.
