More About Bluetooth
Bluetooth is a technology that enables Bluetooth-compliant devices to interconnect easily with each other using a short wireless connection.

A Bluetooth device may cause noise or malfunction, depending on usage, if:
– A part of your body is in contact with the receiving/transmitting system of the Bluetooth device or the Soundbar.
– It is subject to electrical variation from obstructions caused by a wall, corner, or office partition.
– It is exposed to electrical interference from the same frequency-band devices including medical equipment, microwave ovens, and wireless LANs.
Pair the Soundbar with the Bluetooth device while they are close together.
The further the distance between the Soundbar and Bluetooth device, the worse the quality is. If the distance exceeds the Bluetooth operational range, the connection is lost.
In poor reception areas, the Bluetooth connection may not work properly.
The Bluetooth connection only works when it is close to the unit. The connection will be automatically cut off if the Bluetooth device is out of range. Even within range, the sound quality may be degraded by obstacles such as walls or doors.
This wireless device may cause electric interference during its operation.
