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
you are unable to switch the unit to standby when you
press Í ON/STANDBY, press and hold Í ON/
STANDBY to switch to standby. Press Í ON/
STANDBY after this to restart the unit.
Resetting the unit (this resets the unit
settings to the default)
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.
1. Press on the remote controller, select "Factory
Reset" - "Yes" in the menu and press ENTER.
2. In the next screen, select "Yes" and press ENTER.
3. The unit switches to standby and the settings are
reset.

The unit turns off unexpectedly
0 The unit automatically switches to standby when the
"Option" - "Power Management" - "Auto Standby"
setting in the 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 on the front
panel continually blink, there may have been a
malfunction with the amplifier or the protection circuit
may have tripped.
– If the TIMER indicator blinks at approximately
1 second intervals: There may have been a
malfunction in the amplifier section. Unplug the
power cord from the wall outlet immediately and
contact the dealer or our company's support.
– If the TIMER indicator blinks at approximately
0.5 second intervals: The protection circuit may
have tripped due to playback at high volume.
Reduce the volume for playback. Alternatively, the
wires in the speaker cables may have touched the
rear panel or other wires. Connect the wires so
they do not protrude from the speaker jacks.
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.
