2. Important notes
In addition to the items listed under "Using the unit safely" (p. 3), please read and observe the following:
Power supply
• Do not use this instrument on the same power circuit with any
device that will generate line noise (such as an electric motor or
variable lighting system).
• Before connecting the EXR-46 OR to other devices, turn off the
power to all units. This will help prevent malfunctions and/or dam-
age to speakers or other devices.
Placement
• Using the EXR-46 OR near power amplifiers (or other equipment
containing large power transformers) may induce hum. To alleviate
the problem, change the orientation of this instrument or move it
further away from the source of interference.
• This instrument may interfere with radio and television reception.
Do not use it in the vicinity of such receivers.
• Observe the following when using the unit's floppy disk drive. For
further details, refer to "Before using floppy disks (handling the
floppy disk drive)".
• Do not place the unit near devices that produce a strong mag-
netic field (e.g., loudspeakers).
• Install the EXR-46 OR on a solid, level surface.
• Do not move the unit or subject it to vibration while the drive is
operating.
• Do not expose the EXR-46 OR to direct sunlight, place it near
devices that radiate heat, leave it inside an enclosed vehicle, or oth-
erwise subject it to temperature extremes. Excessive heat can
deform or discolor the instrument.
• To avoid possible breakdown, do not use the unit in a wet area, such
as an area exposed to rain or other moisture.
• Do not allow objects to remain on top of the EXR-46 OR. This can be
the cause of malfunction.
Maintenance
• For everyday cleaning wipe the EXR-46 OR with a soft, dry cloth or
one that has been slightly dampened with water. To remove stub-
born dirt, use a mild, non-abrasive detergent. Afterwards, be sure to
wipe the instrument thoroughly with a soft, dry cloth.
• Never use benzene, thinner, 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 instrument's memory
may be lost when it is sent for repairs. 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. Roland assumes no liability
concerning such loss of data.
Additional precautions
• Please be aware that the memory contents can be irretrievably lost
as a result of a malfunction, or the improper operation of the
instrument.
• Use a reasonable amount of care when using the instrument's but-
tons, other controls, and jacks/connectors. Rough handling can lead
to malfunctions.
• Never strike or apply strong pressure to the display.
• When connecting/disconnecting 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.
• A small amount of heat will radiate from the instrument during nor-
mal operation. This is perfectly normal.
• To avoid disturbing your neighbors, try to keep the instrument's vol-
ume at reasonable levels. You may prefer to use headphones, so you
do not need to be concerned about those around you (especially late
at night).
• When you need to transport the instrument, package it in the box
(including padding) that it came in. Otherwise, you will need to use
equivalent packaging materials, or a flightcase.
• Use only a recommended footswitch (DP-2, DP-6, sold separately).
By connecting any other footswitch, you risk causing malfunction
and/or damage to the EXR-46 OR.
• When the EXR-46 OR is used at excessive volumes, the protection
system of its power amplifier stage may come on and mute the
speakers. In that case, reduce the volume setting and wait a few
seconds.
Before using floppy disks (handling the floppy disk
drive)
• Install the unit on a solid, level surface in an area free from vibra-
tion. If the unit must be installed at an angle, be sure the installation
does not exceed the permissible range: upward, 2°; downward, 18°.
• Avoid using the EXR-46 OR immediately after it has been moved to
a location with a level of humidity that is greatly different than its
former location. Rapid changes in the environment can cause con-
densation to form inside the drive, which will adversely affect the
operation of the drive and/or damage floppy disks. When the
EXR-46 OR has been moved, allow it to become accustomed to the
new environment (allow a few hours) before operating it.
• To insert a disk, push it gently but firmly into the drive—it will click
into place. To remove a disk, press the EJECT button firmly. Do not
use excessive force to remove a disk which is lodged in the drive.
• Never attempt to remove a floppy disk from the drive while the
drive is operating (the indicator is lit); damage could result to both
the disk and the drive.
• Remove any disk from the drive before switching the instrument on
or off.
• To prevent damage to the disk drive's heads, always try to hold the
floppy disk in a level position (not tilted in any direction) while
inserting it into the drive. Push it in firmly, but gently. Never use
excessive force.
• To avoid the risk of malfunction and/or damage, insert only floppy
disks into the disk drive. Never insert any other type of disk. Avoid
getting paper clips, coins, or any other foreign objects inside the
drive.
