OPERATIONS
1.5 Turning the System Off
There is no preferred order of components when turning
the system off. However, there is one caution you should
follow:
NOTE: Do not turn the system off while any Source
Device is running and producing sound. Always make
sure all Source Devices are in “Idle” before pressing the
main POWER button.
Failure to do this can produce a noticeable “pop” , and
can, over time, damage your components. If you need to
turn off the sound to the system suddenly, for example,
to take a phone call or to reply to someone, press the
MUTE button.
