Note: If the connection is successful, the soundbar’s profile status will change to “Connected.”

2. Shorten the Wireless Bluetooth Range

shorten the wireless bluetooth range

Whether you’re connecting the soundbar to your TV, mobile device, or computer, it must always remain within a particular radius to maintain the wireless connection.

So, moving the soundbar or the wireless device out of the range will impact the Bluetooth signal and cause a disconnect.

What is the LG Soundbar’s Wireless Radius?

So, the standard connection radius of any model LG soundbar is between 25–30 feet (up to 10 meters) for optimal Bluetooth connection.

Even so, keeping the soundbar or the output device at the 30th feet may cause audio disruptions or drop losses in your wireless Bluetooth connection.

Tip: Stay within a 10 feet radius of the soundbar to support a proper Bluetooth connection!

3. Reset the LG Soundbar’s “BT” Mode

To use the LG soundbar’s Bluetooth, you must activate the “BT” Mode function, before pairing with the device.

To address issues with Bluetooth, you can switch to one of the other available connection modes of the LG soundbar and tune the device back to Bluetooth, so it can refresh.

Here’s how to reset the “BT” mode on the LG soundbar unit:

  1. Press the “F” key on the LG soundbar or the remote control.
  2. Cycle through all available connection modes in the menu.
  3. Wait until the soundbar’s display says “BT” mode once again.
  4. Reconnect with the soundbar and test the connection quality.

If the soundbar maintains a wired connection to another device, cycling through the modes will cause disruptions in the audio output.

So, while performing this step, ensure there are no other audio adapters connected to the LG soundbar, such as an HDMI or Optical cable output unit.

4. Use Soundbar’s “Clear Error” Function
