 Check the network connection (page 21) and the network settings (page 54).  Depending on the usage environment (including the wall material), radio wave reception conditions, or obstacles between the system and the wireless LAN router, the possible communication distance may be shortened. Move the system and the wireless LAN router closer to each other.  Devices that use a 2.4 GHz frequency band, such as a microwave, BLUETOOTH, or digital cordless device, may interrupt communication. Move the unit away from such devices, or turn off such devices.  The wireless LAN connection may be unstable depending on the usage environment, especially while using the BLUETOOTH function of the system. In this case, adjust the usage environment. The wireless router you want is not shown in the wireless network list.  Press BACK to return to the previous screen, and try [Wireless Setup] again (page 21). If the wireless router you want is still not detected, select [New connection registration] from the network list, then select [Manual registration] to input a network name (SSID) manually.

When the input source does not contain much bass sound, as is the case with most TV programs, the bass sound may not be audible.  Press SW  + on the remote control to increase the volume of the subwoofer (page 28).  Set the night mode to [Off]. For details, see "Enjoying Clear Sound with Low Volume at Midnight (NIGHT)" (page 27). Sound skips or has noise.  If there is a device nearby that generates electromagnetic waves, such as a wireless LAN or a microwave oven in use, locate the system apart from it. 62US
