the power cables of the system and peripherals are correctly connected to the
earthed/grounded outlet. Please connect the three-core power plug to the
three-core AC power outlet that is well earthed and within reach. Be sure to use the
earthing/grounding pin of power cord and do not use the patch plug or the
earthing/grounding pin unplugged with cables. In the case that the
earthing/grounding conductors are not installed and it is uncertain whether there is
appropriate earthing/grounding protection, please do not use or attempt to
operate the equipment. You can contact and consult an electrician.
•Please do not push any objects into the openings of the system. Doing so may
cause short circuit of internal components and then lead to fire or electric shock.
