The power plug is not fully inserted.
➔Insert the power plug fully into the power outlet.
The OUTPUT LEVEL knob is set to the MIN level.
➔Set the OUTPUT LEVEL knob properly.
Pin connector cable is not properly connected to the
LINE INPUT jack.
The speaker setting at the amplifier (or receiver) is
incorrect.
➔Check the settings at the amplifier (or receiver).
The input signal is so small that the unit entered
Standby mode.
➔Slightly increase the output level at the amplifier
(or receiver).
If the Standby/On indicator lights up (both red and
blue LEDs) several seconds or minutes after the
sound output stopped, this means that the amp
protection circuit has been activated. In this case, set
the OUTPUT LEVEL knob to the center position,
and disconnect the power cord from the AC outlet.
Wait at least 10 seconds, and then reconnect the
power cord. If that doesn’t solve the issue, contact
your Onkyo dealer.

range.
➔Play a sound source that includes a superbass

➔Fully insert the pin connector plug.
External leakage flux (induction noise by TV, etc.)

➔Relocate the SKW-770 away from the noise
source and re-connect.
