IMPORTANT SAFETY INSTRUCTIONS
Your Unit is designed and manufactured to operate within dened design limits, and misuse may result in electric shock or re. To prevent your Unit from being damaged,
the following rules should be observed for its installation, use, and maintenance. Please read the following safety instructions before operating your Unit. Keep these
instructions in a safe place for future reference.
• Read these instructions.
• Keep these instructions.
• Heed all warnings.
• Follow all instructions.
• Do not use this apparatus near water.
• Clean only with a dry cloth.
• Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
• Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including ampliers) that produce heat.
• Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has
two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not t into your outlet, consult an
electrician for replacement of the obsolete outlet.
• Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
• Only use attachments/accessories specied by the manufacturer.
• Use only with the cart, stand, tripod, bracket, or table specied by the manufacturer, or sold with the apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid injury from tip-over.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged in any way, such as when the power supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been
dropped.
• To reduce the risk of electric shock or component damage, switch o the power before connecting other components to your Unit.
• Unplug the power cord before cleaning your Unit. A damp cloth is sucient for cleaning. Do not use a liquid or a spray cleaner on your Unit. Do not use abrasive
cleaners.
• Always use the accessories recommended by the manufacturer to insure compatibility.
• When moving your Unit from an area of low temperature to an area of high temperature, condensation may form in the housing. Wait before turning on your Unit to
avoid causing re, electric shock, or component damage.
• Slots and openings in the back and bottom of the cabinet are provided for ventilation. To ensure reliable operation of your Unit and to protect it from overheating, be
sure these openings are not blocked or covered. Do not place your Unit in a bookcase or cabinet unless proper ventilation is provided.
• Never push any object into the slots and openings on your Unit enclosure. Do not place any objects on the top of your Unit. Doing so could short circuit parts causing a
re or electric shock. Never spill liquids on your Unit.
• Do not block the subwoofer ports. Allow for 1-2 inches of space around all sides for ventilation.
• WARNING: Exposure to loud sounds can damage your hearing causing hearing loss and tinnitus (ringing or buzzing in the ears). With continued exposure to loud
noises, ears may become accustomed to the sound level, which may result in permanent damage to hearing without any noticeable discomfort.
• When connected to a power outlet, power is always owing into your Unit. To totally disconnect power, unplug the power cord.
• Do not overload power strips and extension cords. Overloading can result in re or electric shock.

Bluetooth Pairing
To pair the sound bar with a Bluetooth device:
1. Press and hold the Bluetooth button on the sound bar or remote for ve (5) seconds.
2. Search for the sound bar (VIZIO M21d) using your Bluetooth device. For more information, refer to the user
documentation that came with the device.
3. Now you can play audio from your Bluetooth device. Volume can be controlled on both your source device and
the sound bar.
In Bluetooth pairing mode, the LED indicators on the display panel on
the front of the sound bar will light up from left to right continuously.
Once the device is paired, the LED indicators will stop flashing.
Bluetooth Device Button Located on the Side of Sound Bar

ENG - 19
Using Bluetooth Mode
1. Your sound bar supports music streaming from devices with Bluetooth capability.
(Device compatibility will vary, see your device’s documentation for more information.)
2. Once you have paired your source device to the sound bar your device should remain paired. (within range)
3. If the source is changed back to Bluetooth, any paired Bluetooth device will reconnect automatically.
4. If the input is changed, the Bluetooth device will disconnect (will stay connected if Auto VA BT is on).
Reduce the volume levels on your device and
on the sound bar before pressing Play. High
volume levels can damage your hearing.
Your sound bar is not equipped with a
microphone, so it cannot operate as a
hands-free device for a smartphone.
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.

Connecting to a Voice Assistant
Make sure your sound bar is turned ON and Eco Power setting is
turned OFF. Refer to Eco Power mode on page 16 to disable.
Your sound bar can connect to a Voice Assistant (VA) device through an AUX VA or Bluetooth connection.
Once connected, your sound bar will now act as the VA speaker.
Features and Benets:
• Voice Assistant Dedicated Input: VA can be active on the sound bar even if the sound bar is set to a different
input with audio playing.
• Auto Muting: If playing audio from the sound bar, the VA will play over the original source audio for 10
seconds. If continued after the 10 seconds, the VA audio will mute the original source audio. Once the VA audio
is stopped the original source audio will resume.
Setup Tips:
• If the VA audio is too low, adjust the volume from the VA device.
• If the start of the response from the VA is cut off, enable “Start of Request” from your VA app settings.
• To disable the VA function, refer to Auto VA on page 13 for more information.
