Using Bluetooth
When using Bluetooth, enable Bluetooth on your mobile phone or any other
device and connect to K-Speak. The Bluetooth device name is located on the
K-Speak rear side.
If required (for example when using a PC), you can connect the USB Bluetooth
adapter to a device (within a 3 meter distance) to make sure you get a stable
Bluetooth connection.
To do so, connect the USB Bluetooth adapter to the computer (preferably on the
side facing the speaker, for better connection). K-Speak connects
automatically.
| Note that sometimes you need to reconnect to Bluetooth after connecting the
adapter. To do so, press the Bluetooth key for 9 seconds and a connection will
be established within 30 seconds.
