Handling caution
• When turning on the AC power in your audio system, always turn on the power
amplifier LAST, to avoid speaker damage. When turning the power off, the power
amplifier should be turned off FIRST for the same reason.
• Do not insert your fingers or hands in any gaps or openings on the device
(vents).
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any
gaps or openings on the device (vents) 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 device or 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.
• Do not apply oil, grease, or contact cleaner to the faders. Doing so may cause
problems with electrical contact or fader motion.
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 qualified Yamaha service
personnel about replacing defective components.
Backup battery
• This device has a built-in backup battery. When you unplug the power cord from
the AC outlet, the current scene data and library data 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!" when you starting up
the system, ( In this case, the Battery field indicates "LOW" or "NO" in the SET
UP screen.) immediately save the data to a USB storage device, then have
qualified Yamaha service personnel replace the backup battery.
