BLUETOOTH® CONNECTION RANGE
The Bluetooth® connection range is a minimum of 10 meters. However, range is typically much larger but not guaranteed.
CONNECTING A DIFFERENT BLUETOOTH® DEVICE
The Bluetooth® module can only support one device connection at a time.
If you need to change devices, repeat the Bluetooth
current device and allows a new device to be connected.

To power off the Bluetooth® module hold down the Bluetooth® ON/OFF button until the PAIR LED turns fully on (not flashing) and then
release the button.
IMPORTANT: Ensure that the volume of your Bluetooth® device is set to an appropriate level as this effectively adds in
another volume control to your system.
