It is very easy. Only five steps are needed.
- Open the glass doors.
- Plug out the cable of your BeoSound.
- Grip firmly one of the glass doors and unfasten firstly the bottom thumb-lock. You will hear a click.
- Do the same with the top thumb-lock.
- Repeat the two last steps with the other glass door.
That is all. Rewind all of the steps to put the glass doors where they were. If you need more clarification just ask.
