Precautions
!! PLEASE READ THIS BEFORE PROCEEDING !!
■ Location
Do not expose the MFC10 to the following
conditions to avoid deformation, discoloration,
or more serious damage.
• Direct sunlight (e.g. near a window).
• High temperatures (e.g. near a heat source,
outside, or in a car during the daytime).
• Excessive humidity.
• Excessive dust.
• Strong vibration.
■ USE THE CORRECT POWER SUPPLY
• Power to the MFC10 should be supplied
only from the appropriate Yamaha AC
adaptor (the PA-3B or another adaptor
specifically recommended by Yamaha). Use
of another adaptor may cause serious
damage to the unit. Also make sure that the
adaptor you have is appropriate for the AC
mains supply voltage in the area where you
intend to use the MFC10. (The correct
input voltage is marked on the adaptor.)
■ Power Supply
• Turn the power switch OFF when the
instrument is not in use.
• The power adaptor should be unplugged
from the AC outlet if the MFC10 is not to
be used for an extended period of time.
• Unplug the MFC10 during electric storms.
• Avoid plugging the MFC10 into the same
AC outlet as appliances with high power
consumption, such as electric heaters or
ovens. Also avoid using multi-plug adaptors
since these can result in reduced sound
quality and possibly damage.
■ Turn Power OFF When Making Connections
• To avoid damage to the MFC10 and other
devices to which it is connected (a sound
system, for example), turn the power
switches of all related devices OFF prior to
connecting or disconnecting audio and MIDI
cables.
■ MIDI Connections
• When connecting the MFC10 to MIDI
equipment, be sure to use high-quality
cables made especially for MIDI data
transmission.
• Avoid MIDI cables longer than about 15
meters. Longer cables can pick up electrical
noise that can causes data errors.
■ Handling and Transport
• Never apply excessive force to the controls,
connectors or other parts of the instrument.
• Always unplug cables by gripping the plug
firmly, not by pulling on the cable.
• Disconnect all cables before moving the
instrument.
• Physical shocks caused by dropping,
bumping, or placing heavy objects on the
instrument can result in scratches and more
serious damage.
■ Cleaning
• Clean the cabinet and panel with a dry soft
cloth.
• A slightly damp cloth may be used to
remove stubborn grime and dirt.
• Never use cleaners such as alcohol or
thinner.
• Avoid placing vinyl objects on top of the
instrument (vinyl can stick to and discolor
the surface).
■ Electrical Interference
• This instrument contains digital circuitry
and may cause interference if placed too
close to radio or television receivers. If this
occurs, move the instrument further away
from the affected equipment.
■ Data Backup
• The MFC10 contains a special read-write
memory without a battery, that retains the
contents of its internal memory even when
the power is turned OFF.
■ Service and Modification
• The MFC10 contains no user serviceable
parts. Opening it or tampering with it in any
way can lead to irreparable damage and
possibly electric shock. Refer all servicing
to qualified YAMAHA personnel.
YAMAHA is not responsible for damage caused by improper handling or operation.
