Acoustic slot

The top of the acoustic slot doubles as a handle so you can lift it.
SUB placement: Make sure at least one side of the slot is free from obstruction. If you place it vertically against a wall, do not block the front opening. If you place the SUB horizontally on the floor, don’t put anything on top of it.

SUB status indicator

LED indicates the SUB status.

• See LED Explanations - SUB for more information.

Ethernet port

Use an Ethernet cable to connect the SUB to your home network.
