Troubleshooting
Before starting the procedure
When operation is unstable, problems may be solved by
simply turning the power on or to standby or
disconnecting/connecting the power cord, rather than
reviewing settings and operations. Try the simple
measures on both the unit and the connected device. If
the problem isn’t fixed after referring to
“Troubleshooting”, resetting the unit to the status at the
time of shipment may solve the problem. Note that your
settings will also be initialized when you reset, so we
recommend that you note down your settings before
doing the following.
Resetting the unit (this resets the unit settings
to the default)
1. Press MENU on the remote controller, select “Factory
Reset” - “Reset Start” and press ENTER.
2. Press ENTER.
3. The unit switches to standby and the settings are
reset.
Power
Cannot turn on the unit
0 Unplug the power cord from the wall outlet, wait 5
seconds or more, then plug it in again.
The unit turns off unexpectedly
0 The unit automatically switches to standby when the
“Option” - “PWR Setting” - “Auto Standby” setting in
the setup menu functions.
0 Check if the speaker cable wires are touching the rear
panel or if the i side and s side have shorted. If there
is contact or shorting, the unit will switch to standby
automatically.
0 If the power turns off and indicators around the
VOLUME dial on the front panel continually blink,
there may have been a malfunction with the amplifier
or the protection circuit may have tripped. The
protection circuit may trip in the following cases.
– When playing at high volumes. Reduce the volume
if this occurs.
– When the wires in the speaker cables have touched
the rear panel or other wires. Reconnect the wires
so they do not protrude from the speaker terminals if
this occurs.
If the same symptoms such as being unable to turn the
unit on happen repeatedly, unplug the power cord from
the wall outlet immediately and contact the dealer or
our company’s support.
Volume reduces after switching to standby
0 This unit protects circuits by reducing the volume to 40
the next time the unit is switched on if the volume was
above 40 when it was switched to standby.
Sound distorted when played at high
volume
0 Sound may be distorted when you play with the
volume set above 30 with Bass settings made or with
the “PM Bass” function enabled. Press TONE on the
remote controller and reduce the level of the “Bass” or
set “PM Bass” to “Off”. (P28)
There is no audio from external devices
0 There is no sound if this unit is muted. Press MUTING
on the remote controller to cancel muting.
0 Confirm that the connection between the output jack
on the external device and the input jack on this unit is
correct.
0 Change the input selector on this unit to the position of
the terminal to which the external device is connected.
0 Check the digital audio output setting on the
connected component. On some game consoles, such
as those that support DVD, the default setting is off.
The display doesn’t light
0 The display may go dim while the DIMMER is working.
Press DIMMER button and change the brightness
level of the display.
Wi-Fi Connection
0 Try plugging/unplugging the power supply of wireless
LAN router and the unit, check the wireless LAN router
power-on status, and try reboot of the wireless LAN

0 Check that the setting of SSID and encryption (WEP,
etc.) is correct. Make sure the network settings of the
unit is properly set.
0 Connection to an SSID that includes multi-byte
characters is not supported. Name the SSID of the
wireless LAN router using single-byte alphanumeric
characters only and try again.
0 When the wireless LAN router setting is at stealth
mode (mode to hide the SSID key) or when ANY
connection is off, the SSID is not displayed. Change
the setting and try again.
