(weee_eu_en_01) Explanation of Graphical Symbols The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed. RISK OF ELECTRIC SHOCK DO NOT OPEN NOTICE To avoid the possibility of malfunction/ damage to the product, or damage to other property, follow the notices below. Handling and maintenance • Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile phone, or other electric devices. Otherwise, the device, TV, or radio may generate noise. • Do not expose the device to excessive dust or vibration, or extreme cold or heat (such as in direct sunlight, near a heater, or in a car during the day), in order to prevent the possibility of panel disfiguration, unstable operation, or damage to the internal components. • Do not place vinyl, plastic or rubber objects on/under the device, since this might discolor the panel of the device or the objects placed on/under the device. • Keep input cables of microphone, etc., devices that contain sensitive circuits, and the power cord at a distance from speaker cables and fasten the speaker cables in place. Since a large amount of current can flow in a speaker cable, a magnetic field will be generated and may produce radio interference and acoustic noise. • When cleaning the device, use a dry and soft cloth. Do not use paint thinners, solvents, cleaning fluids, or chemicalimpregnated wiping cloths. • Condensation can occur in the device due to rapid, drastic changes in ambient temperature–when the device is moved from one location to another, or air conditioning is turned on or off, for example. Using the device while condensation is present can cause damage. If there is reason to believe that condensation might have occurred, leave the device for several hours without turning on the power until the condensation has completely dried out. • Avoid setting all equalizer controls and faders to their maximum. Depending on the condition of the connected devices, doing so may cause feedback and may damage the speakers. • Do not use this device for any purpose other than driving loudspeakers. • When turning on the AC power in your audio system, always turn on the device LAST, to avoid speaker damage. When turning the power off, the device should be turned off FIRST for the same reason. • If you put the device on a table or a rack, do not remove the rubber feet from the device. • Always turn the power off when the device is not in use. Connectors XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-). Precautions for rack mounting This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. If the device is mounted with other devices in an EIA standard equipment rack, internal temperatures can exceed the specified upper limit, resulting in impaired performance or failure. If the device is mounted in a rack, always observe the following requirements to avoid heat buildup: • If the device is mounted in a rack with other devices that generate a significant amount of heat, such as a power amplifier, leave more than 1U of space between the device and other devices (both above and below). Also, make sure to either leave any open spaces uncovered or install appropriate ventilating panels to minimize the possibility of heat buildup. • To ensure sufficient airflow, leave the rear of the rack open and position it at least 10 centimeters from walls or other surfaces. If you’ve installed a fan kit, there may be cases in which closing the rear of the rack will produce a greater cooling effect. Refer to the rack and fan unit manual for details. 이 기기는 가정용(B급) 전자파적합기기로서 주로 가정에서 사용하는 것을 목적으로 하며, 모든 지역에서 사용할 수 있습니다. CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK).
