Connections • Before connecting the device to other devices, turn off the power for all devices. Before turning the power on or off for all devices, set all volume levels to minimum. Handling caution • Do not insert your fingers or hand in any gaps or openings on the device (vents etc.). • Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any gaps or openings on the device (vents, etc.) If this happens, turn off the power immediately and unplug the power cord from the AC outlet. Then have the device inspected by qualified Yamaha service personnel. • Do not use the headphones for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician. • Do not rest your weight on the device or place heavy objects on it, and avoid use excessive force on the buttons, switches or connectors. Backup battery • This device has a built-in backup battery. When you unplug the power cord from the AC outlet, the internal data of current scene is retained. However, if the backup battery fully discharges, this data will be lost. When the backup battery is running low, the LCD display indicates "Low Battery!" during operation or "No Battery!" when starting up the system. In this case, have qualified Yamaha service personnel replace the backup battery. XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-). Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed. Always turn the power off when the device is not in use. The performance of components with moving contacts, such as switches, volume controls, and connectors, deteriorates over time. Consult qualifi ed Yamaha service personnel about replacing defective components. (5)-1 2/2
