Note: Cinema 600 has no consumer facing firmware updates.

If your bar is connected to the internet, unplug the bar from the wall for 10 seconds and plug it back it. The bar will then search for any available updates. After 24 hours, check your firmware versions again. Updates usually happen overnight when the bar is plugged in, but not in use. 

Check for Interference

It is possible that other wireless devices in the room are affecting the surround speakers. Unplug other wireless devices (Bluetooth/Wifi) in the room that may be crossing signals, including your Wifi router. If your router is in the same room, we recommend moving it's location to improve wireless signal. 

Try a Different Outlet

The issue could also be originating from your power outlet. An easy thing to try is changing the location in which the surround speakers are plugged in, making sure the outlet us giving a sufficient amount of power.

If you live in an older house with old wiring, you may want to look into purchasing a ferrite choke to minimize interference from the outlet - Using Ferrite Chokes
