Troubleshooting ■ The unit does not turn on The power plug is not fully inserted. ➔Insert the power plug fully into the power outlet. ■ No sound is output 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. ■ Low sound output The sound source might not include a superbass range. ➔Play a sound source that includes a superbass range. ■ Hum noise Pin connector plug is not inserted completely. ➔Fully insert the pin connector plug. External leakage flux (induction noise by TV, etc.) occurs. ➔Relocate the SKW-770 away from the noise source and re-connect.
