Cinema 600 - How to Check Firmware Versions

If you are unsure about what version firmware you are running on your Cinema 600, you can check by following the steps below:

1. Under the right endcap of the soundbar, short press the surround pairing "PAIR" button once.
2. Once pressed, the source LED on the front of the soundbar should turn purple (indicating that you're checking firmware), and there will be a number of white volume LEDs lit next to it.
3. Note this number of white LEDs - this is the "first" digit of the firmware version number.  "i.e. if you see three white LEDs illuminated, this represents the 3 in 31" below.

4. If you immediately press the pairing button again, the source LED should stay purple, and the number of white, illuminated volume LEDs next to it will be the "second" digit.  "i.e. if you now see only one white LED illuminated, this represents the 1 in 31" below.

   The most up to date firmware version for the Cinema 600 is v31.
