IMPORTANT NOTES
In addition to the items listed under “IMPORTANT SAFETY
INSTRUCTIONS” and “USING THE UNIT SAFELY” on pages 1–3,
please read and observe the following:
Power Supply
•
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.

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.
•
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.
will help prevent malfunctions and/or damage to speakers or other devices.
•
Although the LEDs are switched off when the POWER switch is switched off,
this does not mean that the unit has been completely disconnected from the
source of power. If you need to turn off the power completely, first turn off the
POWER switch, then unplug the power cord from the power outlet. For this
reason, the outlet into which you choose to connect the power cord’s plug
should be one that is within easy reach and readily accessible.

Placement
•
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.

•
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.

•
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.

•
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.

Do not allow objects to remain on top of the keyboard. This can be the cause of
malfunction, such as keys ceasing to produce sound.

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
•
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 impreg-
nated with a mild, non-abrasive detergent. Afterwards, be sure to wipe the unit
thoroughly with a soft, dry cloth.

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).
