WARNING
To ensure that high-volume noise is not output from the
speakers, power-on the equipment starting with the audio
sources, then the mixer and processors, and finally the
amplifiers. Reverse this order when turning the system off.
NOTE
Details of the problem are shown on the display (i).
Selecting the [ ] icon on the “HOME screen” (page 15) with the
main knob calls up the operating log.
NOTICE
Do not unplug the USB flash drive while the [USB] indicator is
flashing. Doing so may cause data in the PX amplifier or USB
flash drive to be corrupted or lost.
NOTE

turn off automatically when panel is not operated (Black-out sta-
tus: page 34).
