Owner’s Manual
• When setting up the device, make sure that the AC outlet
you are using is easily accessible. If some trouble or
malfunction occurs, immediately turn off the power switch
also disconnect the unit from the power supply that is
connected to the EXT DC INPUT jack. Even when the
power switch is turned off, electricity is still flowing to the
product at the minimum level. When you are not using the
product for a long time, make sure to unplug the power
cord from the wall AC outlet.
• If the device is mounted in an EIA standard rack, carefully
read the section “Precautions for Rack Mounting” on page
8. Inadequate ventilation can result in overheating,
possibly causing damage to the device(s), malfunction, or
even fire.
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.
Maintenance
• Periodically inspect and clean the air filter of the front panel
ventilation opening (page 11). Dust and dirt can seriously
degrade the effectiveness of the cooling fan and result in
malfunction or fire.
• Remove the power plug from the AC outlet when cleaning
the device.
Handling caution
• 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,
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 rest your weight on the device or place heavy
objects on it, and avoid use excessive force on the buttons,
switches or connectors.
