Installing the controls

1. Insert the three buttons for the volume rocker switch, the mute button and the standby button into the enclosure.
2. Start with the standby button. Pay close attention to the position of the standby button. There’s a rocker switch on the button that has to face up, i.e. towards the open side of the back cover.
3. Install the mute button and then the volume rocker switch. Once again, pay close attention to the position. The mute button has an orange stripe. This stripe has to face up, i.e. towards the open side of the back cover.
4. The volume rocker switch has to be installed so the plus symbol is between the mute button and the minus symbol.
