TROUBLESHOOTING

Before seeking assistance, check the following.

In case the power is not turned on

Check whether the power cord of the Soundbar is correctly inserted into the outlet.

In case the functions do not work properly

After removing the power cord, insert it again.

Remote the power cord from the external device and try again.

If there is no signal, the Soundbar automatically turns off after a certain period of time. Turn on the power. (See page 10).

In case the remote control does not work

Operate the remote control noting the Soundbar closely.

Replace the batteries with new ones.

In case the Soundbar sound is not output

The volume of the Soundbar is too low or muted. Adjust the volume.

When any external device (STB, Bluetooth device, mobile device, etc.) is connected, adjust the volume of the external device.

For sound output of the TV, select Soundbar. (Samsung TV: Home ( ) → Settings () → Sound → Sound Output → (Select Soundbar)

The cable connection to the Soundbar may not be loose. Remove the cable and connect again.

Remove the power cord completely, reconnect, and turn the power on.

Initialise the product and try again. (See page 33.)

In case Bluetooth connection is not possible

When connecting a new device, switch to "BT PAIRING” for connection. (Press the PAIR button on the remote control or press the (Source) button on the body for at least 5 seconds.)

If the Soundbar is connected to another device, disconnect that device first to switch the device.

Reconnect it after removing the Bluetooth speaker list on the device to connect. (Samsung TV: Home ( ) → Settings ( ) Sound → Sound Output → Bluetooth (Speaker List)

The automatic TV connection may be disabled. While the Soundbar is in “BT READY”, press and hold the button on the Soundbar remote control for 5 seconds to select ON-TV CONNECT. If you see OFF-TV CONNECT, press and hold button again for 5 seconds to switch the selection.

Remove and reconnect the power plug, then try again.

Initialise the product and try again. (See page 33.)

In case Bluetooth sound breaking occurs

Sounds may be breaking due to interference by radio frequency or electronic devices nearby. Keep such devices away from the Soundbar to avoid radio interference. Example: microwave ovens.

Because the device to connect is far away from the Soundbar, sound breaking may occur. Move the device near the Soundbar.

If a part of your body is in contact with the Bluetooth transceiver or the product is installed on metal furniture, sound breaking may occur. Check the installation environment and conditions for use.

In case Wi-Fi connection is not possible

Check whether your wireless router is on.

Turn off the router, turn it back on, and then try again.

When the signal of the wireless router is too weak, connection may not be possible. Move the router near the Soundbar or adjust the installed position with no obstacles.

If your wireless router is new, you will need to reconfigure the speaker’s network settings.

In case the Soundbar is not turned on as soon as the TV is turned on

When you turn off the Soundbar while watching TV, power synchronization with the TV is disabled. First turn off the TV.
