There seems to be a time
lag between the speakers
and the output of the
subwoofer.
• See Automatically setting up for surround sound (MCACC) on page 29 to
set up your system again using MCACC (this will automatically
compensate for a delay in the subwoofer output).
After using the Auto
MCACC Setup, the speaker
size setting (LARGE or
SMALL) is incorrect.
• Low-frequency noise could have been caused by an air conditioner or
motor. Switch off all appliances in the room and rerun the Auto MCACC
Setup.
Can’t operate the remote
control.
• Replace the batteries (refer to page 7).
• Operate within 7 m (23 ft.), 30° of the remote sensor (refer to page 10).
• Remove the obstacle or operate from another position.
• Avoid exposing the remote sensor on the front panel to direct light.
The display is dark or off. • Press DIMMER on the control repeatedly to return to the default.

Sound from the Bluetooth
wireless technology device
is not emitted or the sound

• Check that no object that emits electromagnetic waves in the 2.4 GHz
band (microwave oven, wireless LAN device or Bluetooth wireless
technology apparatus) is near the unit. If such an object is near the unit,
set the unit far from it. Or, stop using the object emitting the
electromagnetic waves.
• Check that the Bluetooth wireless technology device is not too far from
the unit and that obstructions are not set between the Bluetooth wireless
technology device and the unit. Set the Bluetooth wireless technology
device and the unit so that the distance between them is less than about
10 m (32 ft.) and no obstructions exist between them.
• Check that the Bluetooth ADAPTER and the ADAPTER PORT of the unit
are correctly connected.
• The Bluetooth wireless technology device may not be set to the
communication mode supporting the Bluetooth wireless technology.
Check the setting of the Bluetooth wireless technology device.
• Check that pairing is correct. The pairing setting was deleted from this
unit or the Bluetooth wireless technology device. Reset the pairing.

device that supports A2DP profile and AVRCP profile.
