No sound is output or a noise is output when software with
DTS is played back.
Make sure the player’s settings are correct and/or the DTS
signal out is on. Refer to the instruction manual supplied with
the DVD player.
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 23 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 9).
Operate within 7 m (23 ft.), 30º of the remote sensor (refer to
page 9).
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 remote control repeatedly to return to
the default.
The front panel display switches over for no apparent
reason to various different displays.
This happens because the demo display is in operation. To
turn off the demo display, press any button to go back to the
original display, or set the FL Demo Mode to OFF (see The FL
Demo Mode menu on page 41).

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.
