� Avoiding interference
To avoid possible interference, do not place the wireless system near any of the following devices.
The wireless system uses the same radio frequencies as other devices that may be present in your home. e.g.
2.4GHz-band microwave oven
personal computer with 2.4GHz-band wireless LAN
2.4GHz-band cordless phone
The wireless system will automatically seek a clear channel if any of these other devices interfere with its communication. When this happens, the wireless link indicator (� [W] �) flashes on the main unit, and there is a brief interruption in audio coming from the surround speakers. This is the normal operation of the product working to assure the best possible performance of your Home Theater System. If the interference persists, try moving the other devices to another location outside the range of the wireless system.
Speaker installation options
� Attaching to a wall
You can attach all of the speakers to a wall. � The wall or pillar on which the speakers are to be attached should be capable of supporting 10 kg (22 lbs) per screw. Consult a qualified building contractor when attaching the speakers to a wall. Improper attachment may result in damage to the wall and speakers. 1 Drive a screw (not included) into the wall.
� Fitting speaker stands (not included)
Ensure the stands meet these conditions before purchasing them. Note the diameter and length of the screws and the distance between screws as shown in the diagram. � The stands must be able to support over 10 kg (22 lbs). � The stands must be stable even if the speakers are in a high position.
