Hi Pedro,

If the speaker is not responding to remote commands, then it could be the earthing of the display that is the issue. Try grounding the copper ring (next to one of the mounting holes) to the shielding can that covers the DSP/Comms board. See if you can get into the Type menu then... You will need to set the speaker to become a slave and appropriate Left/Right.

Failing that, you can connect via serial and use the virtual remote (Meridian Control Window) to control the speaker.

Good luck,

Steve
