NOTE:

– If the main unit is off, the subwoofer enters standby, and the STANDBY LED turns red after blinking blue.

– Interference may occur if devices using the same frequency are nearby.

– Maximum wireless transmission distance is about 32.8 ft (10 m), varying by environment. Walls (steel-concrete or metallic) can block the signal.

CAUTION:

– Wireless antennas are built-in. Keep away from water/moisture.

– Keep the area around the subwoofer clear of obstructions for optimal performance.

1. Connect the Wireless Receiver Module to 2 Surround Speakers:

– Use the color-coded speaker cables.

– If using a cored HDMI cable, ensure its diameter is less than 0.55 inches (14 mm).

Steps:

1. With the Soundbar and TV turned off, connect an HDMI cable from the HDMI TO TV (eARC/ARC) port on the Soundbar to the HDMI IN (ARC/eARC) port on your TV.

2. Turn on the Soundbar and TV.

3. “TV ARC” should appear on the Soundbar display, and TV sound will play. If “eARC” appears, an eARC connection is established.

– If “TV ARC” or “eARC” doesn’t appear, press the (Multi Function) / (Source) button on the Soundbar or the (Source) button on the remote to select “D.IN”. The display will show “D.IN” then “TV ARC”.

– Ensure the HDMI cable is in the correct port.

– For eARC, ensure the eARC function is enabled in the TV’s settings menu (e.g., Samsung TV: Home → Menu → Settings → All Settings → Sound → Expert Settings → HDMI-eARC Mode (Auto)).

4. Use the TV’s remote control to adjust the Soundbar volume.

NOTE:

– ARC/eARC allows digital audio/video transmission via one HDMI cable.

– If the HDMI cable doesn’t support ARC, this function won’t work.

– For Dolby Digital broadcasts, setting the TV’s Digital Output Audio Format to Dolby Digital (instead of PCM) is recommended for better quality.

– ARC/eARC supports Dolby Atmos®. Ensure the content supports Dolby Atmos®.

Pre-connection Checklist:

– If both HDMI and optical cables are connected, HDMI signal is received first.

– If the optical cable terminals have covers, remove them.

Steps:

– Install on a vertical wall only.

– Avoid installation in places with high temperature or humidity.

– Verify the wall can support the product’s weight. Reinforce if necessary.

– Use fixing screws or anchors appropriate for your wall type (plaster board, iron board, wood, etc.). Fix support screws into wall studs if possible.

– Purchase wall mounting screws: Diameter M5, Length 1 3/8 inches (35 mm) or longer.

– Connect all cables to external devices before mounting.

– Ensure the Soundbar is turned off and unplugged before installation to prevent electric shock.

1. Place the Wall Mount Guide against the wall surface. Ensure it is level. If mounting below a TV, position the Soundbar at least 2 inches (5 cm) below the TV.

2. Align the Wall Mount Guide’s Center Line with the center of your desired installation area (or the center of the TV if mounting below it). Fix the Guide to the wall using tape.

3. Use a pen tip or sharp pencil to mark the wall through the center of the A-TYPE images on each end of the Guide. Remove the Guide.

4. Drill a hole at each marking using an appropriately sized drill bit. If not drilling into studs, insert suitable anchors or mollies first.

– Check the cable connection to the Soundbar. Remove the cable and connect again securely.

– Completely remove the power cord from the wall, reconnect it, and turn the power on.

– Initialize the product and try again.

– Check the LED indicator on the rear of the Subwoofer (and Surround Speakers if using SWA-9100). It should be solid blue.

– If the indicator is blinking blue or is red, reconnect the units (see manual connection steps for Subwoofer or SWA-9100 connection steps).

– Ensure there are no obstacles between the Soundbar and the Subwoofer/Surround Speakers. Move devices to a clear area if needed.

– Other devices nearby sending radio frequency signals (like microwaves, wireless routers) may interrupt the connection. Keep the speakers away from such devices.

– Remove and reconnect the power plug for the Soundbar, Subwoofer, and Surround Speakers.

– Check for objects between the Soundbar and the Subwoofer/Surround speakers. Reposition them to a place without obstructions.

– If the Subwoofer and Surround Speaker are too far from the Soundbar, move them closer.

– If the Soundbar is near an instrument or electrical device causing radio interference (e.g., wireless router), move the Soundbar away from it.

– If your TV is connected wirelessly, try changing the TV network connection status from wireless to wired.

– The original volume of the content you are playing may be low. Try adjusting the Subwoofer level using the WOOFER LEVEL button on the remote.

– Bring the Subwoofer speaker closer to the Soundbar main unit.

– Check that the HDMI cable is correctly connected to the port labeled ARC or eARC on the TV and the HDMI TO TV (eARC/ARC) port on the Soundbar.

– Connection might fail due to the connected external device (set-top box, game console). Try connecting the Soundbar directly to the TV’s ARC/eARC port.

– Ensure HDMI-CEC is activated on the TV menu. (e.g., Samsung TV: Home → Menu → Settings → All Settings → Connection → External Device Manager → Anynet+ (HDMI-CEC) ON).

– For an eARC connection, ensure the eARC function in the TV menu is set to On/Auto. (e.g., Samsung TV: Home → Menu → Settings → All Settings → Sound → Expert Settings → HDMI-eARC Mode (Auto)).

– Your connected device (e.g., TV) might be unable to play the input signal format.

– Remove and reconnect the power plug for the Soundbar, then try again.

– Initialize the product and try again.

– Some devices (e.g., microwaves, wireless routers) can cause radio interference if too close. Move them away from the Soundbar.

– If the connected Bluetooth device moves too far from the Soundbar, the sound may drop out. Move the device closer.

– If a part of your body contacts the Bluetooth transceiver or if the product is installed on metal furniture, sound may drop out. Check the installation environment and usage conditions.

– Check if your wireless router is turned on.

– Turn the router off, wait a minute, turn it back on, and try connecting again.

– The Soundbar won’t connect if the wireless signal is too weak. Try moving the router closer to the Soundbar, or remove any obstacles between them.

– If you have a new wireless router, you’ll need to reconfigure the Soundbar’s network settings using the SmartThings app.

– When you turn off the Soundbar while watching TV, power synchronization with the TV is disabled. Turn off the TV first, and the Soundbar should turn off with it (if HDMI-CEC is enabled).

(Applicable models only – Q910C)

– The AVA function will not be available when using the Q-Symphony function.

– The AVA function will not be available when the microphone is turned off.
