Important Notes - Roland Classic C-380 Owner's Manual

IMPORTANT NOTES

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.
• 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.
• Although the LCD and 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.
• This device may interfere with radio and television reception. Do not
use this device in the vicinity of such receivers.
• 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. Also, do not allow lighting devices that
normally are used while their light source is very close to the unit
(such as a piano light), or powerful spotlights to shine upon the same
area of the unit for extended periods of time. 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 rubber, vinyl, or similar materials to remain on the unit
for long periods of time. Such objects can discolor or otherwise
harmfully affect the finish.
• Do not allow objects to remain on top of the keyboard or pedal board.
This can be the cause of malfunction, such as keys ceasing to produce
sound.
• Do not paste stickers, decals, or the like to this instrument. Peeling
such matter off the instrument may damage the exterior finish.

Maintenance
• To clean the unit, use a dry, soft cloth; or one that is slightly
dampened. Try to wipe the entire surface using an equal amount of
strength, moving the cloth along with the grain of the wood. Rubbing
too hard in the same area can damage the finish.
• Never use benzine, thinners, alcohol or solvents of any kind, to avoid
the possibility of discoloration and/or deformation.
Repairs and Data
• Please be aware that all data contained in the unit's memory may be
lost when the unit is sent for repairs. Important data should always be
backed up on a USB memory, or written down on paper (when
possible). During repairs, due care is taken to avoid the loss of data.
However, in certain cases (such as when circuitry related to memory
itself is out of order), we regret that it may not be possible to restore
the data, and Roland assumes no liability concerning such loss of
data.
Before Using USB Memory
Using USB memories
• Use USB memory available from Roland. Proper operation cannot be
guaranteed if other USB device is used.
• We cannot guarantee correct operation if other brands of USB
memory are used. Note that only USB memory keys can be used—
never use any other kind of USB device.
• When connecting USB memory, position it horizontally with the USB
connector and insert it without using excessive force. The USB
MEMORY connector may be damaged if you use excessive force when
inserting USB memory.
• Do not insert anything other than USB memory (e.g., wire, coins, other
types of device) into the USB connector. Doing so will damage the
USB connector.
• Do not apply excessive force to the connected USB memory.
• Carefully insert the USB memory all the way in—until it is firmly in
place.
• Never touch the terminals of the USB memory. Also, avoid getting the
terminals dirty.
• USB memories are constructed using precision components; handle
the USB memories carefully, paying particular note to the following.
• To prevent damage to the USB memories from static electricity, be
sure to discharge any static electricity from your own body before
handling the USB memories.
• Do not touch or allow metal to come into contact with the contact
portion of the USB memories.
• Do not bend, drop, or subject USB memories to strong shock or
vibration.
• Do not keep USB memories in direct sunlight, in closed vehicles, or
other such locations.
• Do not allow USB memories to become wet.
• Do not disassemble or modify the USB memories.
