Important Notes
Power Supply: Use of Batteries
301
• Do not connect this unit to same electrical outlet that is
being used by an electrical appliance that is controlled by
an inverter (such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that contains a
motor. Depending on the way in which the electrical
appliance is used, power supply noise may cause this unit
to malfunction or may produce audible noise. If it is not
practical to use a separate electrical outlet, connect a
power supply noise filter between this unit and the
electrical outlet.
302
• The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a cause
for concern.
307
• Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions and/
or damage to speakers or other devices.
Placement
351
• Using the unit near power amplifiers (or other equipment
containing large power transformers) may induce hum. To
alleviate the problem, change the orientation of this unit;
or move it farther away from the source of interference.
352a
• This device may interfere with radio and television
reception. Do not use this device in the vicinity of such
receivers.
352b
• Noise may be produced if wireless communications
devices, such as cell phones, are operated in the vicinity of
this unit. Such noise could occur when receiving or initiating a call, or while conversing. Should you experience
such problems, you should relocate such wireless devices
so they are at a greater distance from this unit, or switch
them off.
354a
• Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.
355b
• When moved from one location to another where the
temperature and/or humidity is very different, water
droplets (condensation) may form inside the unit. Damage
or malfunction may result if you attempt to use the unit in
this condition. Therefore, before using the unit, you must
allow it to stand for several hours, until the condensation
has completely evaporated.
360
• Depending on the material and temperature of the surface
on which you place the unit, its rubber feet may discolor or
mar the surface.
You can place a piece of felt or cloth under the rubber feet
to prevent this from happening. If you do so, please make
sure that the unit will not slip or move accidentally.
Maintenance
401a
• For everyday cleaning wipe the unit with a soft, dry cloth
or one that has been slightly dampened with water. To
remove stubborn dirt, use a cloth impregnated with a mild,
non-abrasive detergent. Afterwards, be sure to wipe the
unit thoroughly with a soft, dry cloth.
402
• Never use benzine, thinners, alcohol or solvents of any
kind, to avoid the possibility of discoloration and/or deformation.
Additional Precautions
553
• Use a reasonable amount of care when using the unit’s
buttons, sliders, or other controls; and when using its jacks
and connectors. Rough handling can lead to malfunctions.
554
• Never strike or apply strong pressure to the display.
556
• When connecting / disconnecting all cables, grasp the
connector itself—never pull on the cable. This way you will
avoid causing shorts, or damage to the cable’s internal
elements.
558a
• To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use
headphones, so you do not need to be concerned about
those around you (especially when it is late at night).
559a
• When you need to transport the unit, package it in the box
(including padding) that it came in, if possible. Otherwise,
you will need to use equivalent packaging materials.

Important Notes
Handling Floppy Disks
651
• Floppy disks contain a plastic disk with a thin coating of
magnetic storage medium. Microscopic precision is
required to enable storage of large amounts of data on
such a small surface area. To preserve their integrity,
please observe the following when handling Floppy disks:
• Never touch the magnetic medium inside the disk.
• Do not use or store Floppy disks in dirty or dusty areas.
• Do not subject Floppy disks to temperature extremes
(e.g., direct sunlight in an enclosed vehicle). Recommended temperature range: 10 to 50˚C (50 to 122˚F).
• Do not expose Floppy disks to strong magnetic fields,
such as those generated by loudspeakers.
652
• Floppy disks have a “write protect” tab which can protect
the disk from accidental erasure. It is recommended that
the tab be kept in the PROTECT position, and moved to the
WRITE position only when you wish to write new data onto
the disk.
fig.DiskProtect.e.eps
Rear side of the disk
Write
(can write new data onto disk)
Handling CD-ROMs
801
• Avoid touching or scratching the shiny underside (encoded
surface) of the disc. Damaged or dirty CD-ROM discs may
not be read properly. Keep your discs clean using a
commercially available CD cleaner.
Write Protect Tab
653
Protect
(prevents writing to disk)
• The identification label should be firmly affixed to the disk.
Should the label come loose while the disk is in the drive, it
may be difficult to remove the disk.
654
• Store all disks in a safe place to avoid damaging them,
and to protect them from dust, dirt, and other hazards. By
using a dirty or dust-ridden disk, you risk damaging the
disk, as well as causing the disk drive to malfunction.
Using USB Memory
704
• Carefully insert the USB memory all the way in—until it is
firmly in place.
705
• Never touch the terminals of the USB Memory. Also, avoid
getting the terminals dirty.
708
• USB Memory are constructed using precision components;
handle the cards carefully, paying particular note to the
following.
• To prevent damage to the cards from static electricity, be
sure to discharge any static electricity from your own body
before handling the cards.
• Do not touch or allow metal to come into contact with the
contact portion of the cards.
• Do not bend, drop, or subject cards to strong shock or vi-
bration.
• Do not keep cards in direct sunlight, in closed vehicles, or
other such locations (storage temperature: -25 to 85˚ C).
• Do not allow cards to become wet.
• Do not disassemble or modify the cards.

To use the remote control, point the remote control toward the MT-90U’s sensor and
operate it within the specified operating range.
MT-90U Basic Operation
NOTE
The operating range is about 4 meters away from and 30 degrees to the right
and left of the sensor.
Some notes on using the remote control
• The remote control does not function when two or more buttons are pressed at the same time.
• Even within the sensor range, the remote control may not function if something is obstructing
the sensor path, or if the remote is held at an awkward angle.
• Using the remote near other devices that use infrared rays, or using a remote other than the
one supplied with the MT-90U can cause malfunction.
• Battery life varies depending on how the remote is used. When the battery wears down, the
sensor range decreases. The battery should be replaced when this happens.
• If you are not going to use the remote control for a long period of time, take the battery out
and store it somewhere for use later.
• Shining a bright light, such as a spot light, on the remote sensor can decrease the sensor’s
responsiveness.
• Use only the specified type (model no. CR2025) of lithium battery. Be sure to insert it as
directed (to ensure correct polarity).
Tuning with the MT-90U
Match the pitches of the instruments you are using to a standard pitch with the MT-90U
for a beautiful, resonant sound. Matching instruments to a standard pitch is called
“tuning.”
What is standard pitch?
The middle A note (440Hz), also known as “concert A,” is the standard tuning pitch.
