The sound skips or noise is generated. (HT-A9)

If the issue occurs, follow these troubleshooting steps - in order - to see if the issue is resolved:

1. Set the RF Channel to Off, then back On: Select Setup → Advanced Settings → Speaker Settings → Wireless Speaker Settings → RF Channel to Off, then set to On.
   Notes:
   • 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.
2. Set the Wireless Playback Quality to Priority on Stable Connection: Select Setup → Advanced Settings → Speaker Settings → Wireless Speaker Settings → Wireless Playback Quality, and set it to Priority on Stable Connection.
3. Set the distance between a wireless LAN router and the control box: Install the control box and speakers at a distance of at least 1.5 m (5 ft) from any wireless LAN router (a).
   Note: The issue may be also improved by changing the wireless LAN router antenna’s direction or angle.
4. Check the control box installation condition and wireless environment:
   • If a device that generates electromagnetic radiation is nearby, such as a wireless LAN device or microwave oven, move the speaker system away from that device.
   • Turn off any other wireless LAN devices that are not in use to reduce the interference, and then check to see if the issue is resolved.
     Note: If the issue is resolved, change the network connection of the peripheral device from wireless LAN to wired LAN, if possible.
   • The control box and speakers are installed too far away from each other. Bring them closer together.
   • If there is any obstacle between the control box and speakers, remove or move the control box and speakers away from the obstacle.
   • Do not install the control box too far back on a shelf. Install the control box in or on a shelf so that the front panel display is not hidden.
   • Move the control box, change the direction of the control box, or install the control box far away from a TV.
   • Interference between the network connection and speaker connection may occur. Try one of the following:
     • Change the wireless LAN connection of the control box and the router to a wired LAN connection.
     • Switch the band of the wireless LAN router to 2.4 GHz, then set up the wireless network connection between the speaker system and the wireless LAN router again using a 2.4 GHz band.
5. Reset the speaker system.
   Note: For details on how to reset the speaker system, refer to the Help Guide.
