NOTES
•Do not connect the power cord of this product or your TV to a wall outlet until all connections
between components are complete.
•Before moving or installing this product, be sure to turn off the power and disconnect the power cord.
•If the main unit is powered off, the wireless subwoofer will go into stand-by mode and the
STANDBY LED on the rear of the sub-woofer will turn red after blinking blue several times.
•If you use a device that uses the same frequency (5.8GHz) as the Soundbar near the Soundbar,
interference may cause some sound interruption.
•The maximum transmission distance of the main unit’s wireless signal is about 32.8 ft (10 m), but
may vary depending on your operating environment. If a steel-concrete or metallic wall is between
the main unit and the wireless subwoofer, the system may not operate at all because the wireless
signal cannot penetrate metal.
PRECAUTIONS
•Wireless receiving antennas are built into the wireless subwoofer. Keep the unit away from water
and moisture.
•For optimal listening performance, make sure that the area around the wireless subwoofer and the
Wireless Receiver Module (sold separately) is clear of any obstructions.

04 CONNECTING TO YOUR TV
Hear TV sound from your Soundbar through wired or wireless connections.
•When the Soundbar is connected to selected Samsung TVs, the Soundbar can be controlled using
the TV’s remote control.
– This feature is supported by 2017 and later Samsung Smart TVs that support Bluetooth when
you connect the Soundbar to the TV using an optical cable.
– This function also allows you to use the TV menu to adjust the sound eld and various settings
as well as the volume and mute.
Method 1. Connecting with a Cable
When the audio in a broadcast is encoded in Dolby Digital and the “Digital Output Audio Format” on
your TV is set to PCM, we recommend that you change the setting to Dolby Digital. When the setting on
the TV is changed, you will experience better sound quality. (The TV menu may use different words for
Dolby Digital and PCM depending on the TV manufacturer.)

connected mobile device to the Soundbar.
•BT PAIRING : In this mode, you can connect a new device to the Soundbar. (Press the PAIR button
on the remote control or press and hold the (Source) button on the top of the Soundbar for
more than 5 seconds while the Soundbar is in “BT” mode.)
NOTES
•If asked for a PIN code when connecting a Bluetooth device, enter <0000>.
•In Bluetooth connection mode, the Bluetooth connection will be lost if the distance between the
Soundbar and the Bluetooth device exceeds 32.8 ft (10 m).
•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 eld around the Soundbar.
– If several Bluetooth devices are simultaneously paired with the Soundbar.
