B4.2 MEDIAMIX
To disconnect
:
•
Tap on the existing Bluetooth connection in your source device
•
Wait for the dual-tone beep from the unit
•
The devices are now unpaired and the B4.2 unit is ready to be paired with a different device.
Please note that the maximum distance of operation between your source device and the unit depends on many factors,
such as other interfering signals, the position of the unit in the room, the position of the source device in the room, and
the antenna/Bluetooth hardware design of the source device. Bluetooth can work over a distance of maximum 10m.
However, certain hardware combinations or the presence of interfering signals can reduce this distance significantly. The
manufacturer of this device does not grant any specific operating distance and cannot take any liability for dropouts. For
critical applications, we recommend to avoid wireless connections.
