No sound is heard Sounds fluctuate (suddenly become loud or soft). Suddenly no sound comes out. Is the unit pugged in? Signals are too weak or volume level is too low. Is the VOLUME knob turned to the MIN position? Connections are incorrect, or loose. Audio signals through the amplifier are extremely weak. The built-in protective circuit is working. The unit is overloaded because of a large volume. Plug the AC power cord firmly into the AC outlet. This is not a malfunction. If this happens, cancel Auto Power On/Standby. Turn the VOLUME knob until a suitable volume is found. Check the connections. If incorrect, redo the corrections. (See pages 4 and 5.) Increase the volume level on the amplifier. Lower the volume level on the amplifier so that the symptom will not occur.

If the power lamp lights in green (in operation). 1 Turn down the volume of the playing source. 2 Turn off the power of the playing source, 3 Turn on the power of the playing source, then 4 Adjust the volume of the playing source.
