Speaker system
- Use a screwdriver (+) for assembling the speakers.
- Do not hold the speakers in one hand to avoid injury, you may drop the speakers when carrying them.
■ When attaching the speakers to a wall
The wall or pillar on which the speakers are to be attached should be capable of supporting 33 kg per screw. Consultation with a qualified installation specialist is recommended when attaching the speakers to a wall. Improper attachment may result in damage to the wall and speakers, and personal injury.
■ When placing the speakers in front of the TV

- If the stands are being used
Move the speakers further away from the TV. If the TV still does not function properly, try removing the stands. - If the stands are not used
Move the speakers further away from the TV. If the TV still does not function properly, try placing them beside the TV ( ⇒ 8).
Active subwoofer
When carrying the active subwoofer

A Do not hold the active subwoofer from this opening.
The parts inside (speaker unit) may be damaged.
B Always hold the bottom of the active subwoofer when moving it.
Wireless interference
To avoid interference, maintain the following distances between the main unit/active subwoofer and other electronic devices that use the same radio frequency (2.4 GHz and 5 GHz band).

© Main unit/active subwoofer
D Wireless LAN: approx. 2 m
E Cordless phone and other electronic devices: approx. 2 m

- Place the active subwoofer within a few meters of the main unit and in a horizontal position with the top panel faced upward.
- Do not use the main unit or active subwoofer in a metal cabinet.
- Placing the active subwoofer and the speakers too close to the walls and corners can result in excessive bass. Cover walls and windows with thick curtains.
- If irregular colouring occurs on your TV, turn the TV off for about 30 minutes. If it persists, move the speakers further away from the TV.

Connection with the TV
1 Verify if the TV's HDMI terminal is labelled "HDMI (ARC)".
Connection differs depending on the label printed next to the HDMI terminal.
Labelled "HDMI (ARC)": Connection A
Not Labelled "HDMI (ARC)": Connection B
■ What is ARC?
ARC is an abbreviation of Audio Return Channel, also known as HDMI ARC. It refers to one of the HDMI functions. When you connect the main unit to the terminal labelled "HDMI (ARC)", the optical digital audio cable that is usually required in order to listen to sound from a TV is no longer required, and TV pictures and sound can be enjoyed with a single HDMI cable.

Make the connection.
