LS9-16/32 Owner’s Manual
• 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.
• Be sure to connect to a properly grounded power source. A ground screw is
provided on the rear panel of this device for maximum safety and shock
prevention. If the mains outlet is not grounded, be sure to connect the
ground screw to a confirmed ground point before plugging the device into
the mains. Improper grounding can result in electrical shock.
• 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, 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 apply oil, grease, or contact cleaner to the faders. Doing so may
cause problems with electrical contact or fader motion.
• 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.
• 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 (the Battery field also indicates “LOW” or
“NO” in the MISC SETUP screen.) In this case, immediately save the data
to a USB memory, then have qualified Yamaha service personnel replace
the backup battery.
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.
