• To use the surround back speakers, set [Surround Back] (page 50) in [Speaker Settings] to [Yes] while performing
the Easy Setup (page 28).
Installing the speakers on a wall
• Contact a screw shop or installer regarding the wall material or screws to be used.
• Use screws that are suitable for the wall material and strength. As a plaster board wall is especially fragile, attach
the screws securely to a beam and fasten them to the wall. Install the speakers on a vertical and flat wall where
reinforcement is applied.
• Sony is not responsible for accidents or damage caused by improper installation, insufficient wall strength or
improper screw installation, natural calamity, etc.
Before installing the front speakers of BDV-E870 on a wall, you need to disassemble the speakers. You
can install the upper part of the speakers on a wall.
