Important Notes
6
Power Supply
Do not use this unit on the same power circuit with any
device that will generate line noise (such as an electric
motor or variable lighting system).
The AC adaptor will begin to generate heat after long
hours of consecutive use. This is normal, and is not a
cause for concern.
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
Using the unit near power amplifiers (or other equip-
ment 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.
Do not expose the unit to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed vehi-
cle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the unit.
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 impregnated with a
mild, non-abrasive detergent. Afterwards, be sure to
wipe the unit thoroughly with a soft, dry cloth.
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 in another
MIDI device (e.g., a sequencer), 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.
Memory Backup
This unit contains a battery which powers the unit’s
memory circuits while the main power is off. When this
battery becomes weak, the message shown below will
appear in the display. Once you see this message, have
the battery replaced with a fresh one as soon as possible
to avoid the loss of all data in memory. To have the bat-
tery replaced, consult with your retailer, the nearest
Roland Service Center, or an authorized Roland distribu-
tor, as listed on the “Information” page.
Additional Precautions
Unfortunately, it may be impossible to restore the con-
tents of data that was stored in another MIDI device (e.g.,
a sequencer) once it has been lost. Roland Corporation
assumes no liability concerning such loss of data.
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 mal-
functions.
Never strike or apply strong pressure to the display.
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 inter-
nal elements.
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).
This instrument is designed to minimize the extraneous
sounds produced when it's played. However, since
sound vibrations can be transmitted through floors and
walls to a greater degree than expected, take care not to
allow these sounds to become a nuisance to neighbors,
especially when performing at night and when using
headphones.
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.
