Various reasons can cause noise interference to the sound from the subwoofer or rear speakers. Try the following solutions:
- Move the speaker system away from any device that generates electromagnetic waves, such as a wireless LAN device or a microwave oven.
- Remove any obstacle between the Sound Bar and Subwoofer or Rear speaker, or move the Sound Bar and speakers away from the obstacle.
- Bring the Sound Bar and Subwoofer or Rear Speaker closer together.
- To reduce interference that may occur from a peripheral device on the same wireless LAN connection as Sound Bar and speakers, change the network connection of other peripheral devices (TV, Blu-ray Disc Player and so on) to a wired LAN.
- Follow these steps to switch the RF Channel to Off and then back to On again:
- Press the HOME button on the Sound Bar remote control.
- Select Setup → Advanced Settings.
- Select Speaker Settings → Wireless Speaker Settings.
- In the RF Channel setting, select Off once, and turn the setting On again.
- We recommend the RF Channel setting is set to On (default setting: On). The Sound Bar automatically selects the best channel for transmission when RF Channel is set to On, which makes it stronger against wireless interference.
- If the sound issue persists, try to turn Off the setting.
- It may take 1 minute to reconnect after you change the RF Channel settings.
- The frequency setting is deleted after disconnecting the power cord. If you disconnect the power cord for some reason, switch RF Channel from Off to On again.
