Pressing the ON key momentarily will activate,or deactivate the zone.The red LED beside the
ON button should light,and you may hear the audio source playing,or you may need to select
a source and adjust the volume before the source can be heard.When the zone has been
powered on for the first time,the LED’s beside each source will cascade until one has been
selected.If you do not get any lights,or do not hear audio sources make a note of the
