                                                   WARNING

                    Always refer to the operation manual when working near locations at
                    which the alert mark, shown on the left, is attached. If the operation, etc.,
                    is performed without heeding the advice in the operation manual, there is
                    a risk of personal injury. In addition, the equipment performance may be
                    reduced.
                    Moreover, this alert mark is sometimes used with other marks and de-
                    scriptions indicating other dangers.




                                                   WARNING
                    When supplying AC power to this equipment, connect the accessory 3-pin
                    power cord to a 3-pin grounded power outlet. If a grounded 3-pin outlet is
                    not available, use a conversion adapter and ground the green wire, or con-
                    nect the frame ground on the rear panel of the equipment to ground. If
                    power is supplied without grounding the equipment, there is a risk of re-
                    ceiving a severe or fatal electric shock.




                                                   WARNING
                    This equipment cannot be repaired by the operator. DO NOT attempt to re-
           Repair
                    move the equipment covers or to disassemble internal components. Only
                    qualified service technicians with a knowledge of electrical fire and shock
                    hazards should service this equipment. There are high-voltage parts in this
    WARNING         equipment presenting a risk of severe injury or fatal electric shock to un-
                    trained personnel. In addition, there is a risk of damage to precision com-
                    ponents.




                                                   WARNING
