time.

Operation

Make certain that speakers and input sources are properly connected before switching
on.

Keep volume levels at minimum gain before switching on.

NOTE: The system’s operation is delayed by approximately three seconds after pressing
the AC Mains power switch. This is due to the built-in protection circuitry, designed to
protect the speakers and other system components.
