Cinema 800 - How to Check Firmware Versions

You can check the various, current firmware version numbers on your Cinema 800 by pressing the small surround pairing button under the right end-cap. (shown in image below)

On the front of the bar, the LED display will show the different firmware versions. Keep pressing this pairing button to scroll through all the firmware currently active on your device. It should display in order as follows:

MCU > WIFI > DSP > SUR T > SUR R > SUR L > SUB T > SUB R > HDMI
