BLUETOOTH AUDIO PAIRING
To pair the sound bar with a Bluetooth device:
1. Press and hold the Bluetooth button 
on the sound bar or on the remote for five (5) seconds. When the sound bar is in Bluetooth Pairing Mode, the LED Indicators on the Display Panel on the front of the Sound Bar will light sequentially from bottom to top and back again.
Once the device is paired, the LED Indicators will stop flashing.
2. You can now search for the sound bar (VIZIO SB3621n) using your Bluetooth device. For more information, refer to the user documentation that came with the device.
3. Play audio from your Bluetooth device. Volume can be controlled on your source device and the sound bar.
USING BLUETOOTH MODE
Your sound bar supports music streaming from smartphones, tablets, and computers with Bluetooth capability. Device compatibility will vary, see your device’s documentation for more information. Once you have paired your source device to the sound bar, as long as you stay within range of the sound bar, your device should remain paired. If the input is changed, the Bluetooth device will disconnect. If the source is changed back to Bluetooth, the last paired bluetooth device will reconnect automatically.
Tips: Your sound bar is not equipped with a microphone, so it cannot operate as a hands-free device for a smartphone.
Maximizing Signal
A Bluetooth signal has a range of up to 30 feet. Keep in mind that Bluetooth is a compressed audio format, so streamed music may lose some integrity when compared to a wired connection.
Try the following if your sound quality is less than optimal:
- If you hear any break-up or disconnect while streaming music from your device, move the source device closer to the sound bar.
- Be sure that there are no solid obstructions in the line-of-sight between the sound bar and the source device.
- Other wireless devices can affect Bluetooth range, including wireless security cameras, wireless video baby monitors, cordless phones, and microwave ovens. Turning off or moving these devices may improve Bluetooth range.
WARNING: Reduce the volume levels on your device and on the sound bar before pressing Play. High volume levels can damage your hearing.
ADVANCED SETUP

CONNECTING A SUBWOOFER
The Subwoofer has already been paired with the Sound Bar by VIZIO. However, the Subwoofer may need to be re-linked to the Sound Bar if there is no sound coming from the Subwoofer.

1. First confirm that the power LED is illuminated. Press and hold the Pairing button on the back of the Subwoofer for 5 seconds. The LED on the back of the Subwoofer will begin to blink.
2. Press and hold the Power button on the top of the Sound Bar for 5 Seconds. The LED indicators on the front will flash 3 times. The Subwoofer is now linked with the Sound Bar.

HELP & TROUBLESHOOTING
| There is no power. | Press the POWER button on the remote control or on the top of your Sound Bar. Ensure the power cord is securely connected. Plug a different device into the electrical outlet to verify that the outlet is working correctly. |
| There is no sound. | Increase the volume. Press Volume Up on the remote control or on the top of your Sound Bar. Press MUTE on the remote to ensure the Sound Bar is not muted. Press INPUT on the remote or on the top of your Sound Bar to select a different input source. When using either of the Digital Inputs, if there is no audio: (A) Try setting the TV output to PCM or (B) Connect directly to your Blu-ray/other source, some TVs do not pass through digital audio. On digital inputs, the input LEDs will flash rapidly if an unsupported format is present. Set the source to output PCM. Your TV may be set to variable audio output. Confirm that the audio output setting is set to FIXED or STANDARD, not VARIABLE. Consult your TV’s user manual for more detailed information. If using Bluetooth, ensure that the volume on your source device is turned up and that the device is not muted. |
| I hear buzzing or humming. | Ensure all cables and wires are securely connected. Connect a different source device (TV, Blu-ray player, etc) to see if the buzzing persists. If it does not, the problem may be with the original device. Connect your device to a different input on the Sound Bar. |
| The remote isn’t working. | Replace the remote batteries with new ones. Point the remote directly at the center of the Sound Bar when pressing a button. If using a Bluetooth connection, some of the buttons on the remote may not be supported by the streaming application. (e.g., Pandora doesn’t support the Back button.) |
