Samsung HW-Q70T Full Manual page 25

If the device fails to connect
• If you have an existing Soundbar (e.g., [AV] Samsung Soundbar Q70T) on the list of speakers on
the Samsung TV, delete it.
• Then repeat steps 1 through 3.
Disconnecting the Soundbar from the Samsung TV
Press the (Source) button on the top panel or on the remote control and switch to any mode but "BT".
• Disconnecting takes time because the Samsung TV must receive a response from the Soundbar.
(The time required may differ, depending on the Samsung TV model.)
What is the difference between BT READY and BT PAIRING?
• BT READY : In this mode, you can reconnect any Samsung TV or mobile device that was
connected before.
• BT PAIRING : In this mode, you can connect a new device to the Soundbar.
(Press the PAIR button on the Soundbar remote control or press and hold the
button on the top of the Soundbar for more than 5 seconds while the Soundbar is in "BT" mode.)
Notes on Bluetooth connection
• Locate a new device within 3.28 ft (1 m) to connect via Bluetooth communication.
• If asked for a PIN code when connecting a Bluetooth device, enter <0000>.
• The Soundbar automatically turns off after 18 minutes in the Ready state.
• The Soundbar may not perform Bluetooth search or connection correctly under the following
circumstances:
– If there is a strong electrical field around the Soundbar.
– If several Bluetooth devices are simultaneously paired with the Soundbar.
– If the Bluetooth device is turned off, not in place, or malfunctions.
• Electronic devices may cause radio interference. Devices that generate electromagnetic waves
must be kept away from the Soundbar main unit - e.g., microwaves, wireless LAN devices, etc.
