Important Notes - Roland VIMA JM-8 Owner's Manual

Important notes

In addition to the items listed under "Using the unit safely" on p. 5, 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.
• 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 JM-8 near power amplifiers (or other equipment con-
taining 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 device may interfere with radio and television reception. Do
not use it 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.
• Observe the following when using the JM-8's EXTERNAL MEMORY
port (USB) and CD drive. For further details, refer to "Before using
external USB storage devices" and "Before Using the CD drive" on
p. 8.
• Do not place the unit near devices that produce a strong mag-
netic field (e.g., loudspeakers).
• Install the unit on a solid, level surface.
• Do not move the unit or subject it to vibration while the drive is
operating.
• When moved from one location to another where the temperature
and/or humidity is very different, water droplets (condensation)
may form inside the JM-8. 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.
• 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 pre-
vent 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 JM-8 with a soft, dry cloth or one
that has been slightly dampened with water. To remove stubborn
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.
• 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 storage device, 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.
Additional precautions
• Unfortunately, it may be impossible to restore the contents of data
that was stored on the internal hard disk, a USB storage device or
a CD once it has been lost. Roland Corporation assumes no liability
concerning such loss of data.
• Use a reasonable amount of care when using the JM-8's buttons,
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.
• To avoid disturbing your neighbors, try to keep the JM-8's volume
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 unit, package it in the box
(including padding) that it came in, if possible. Otherwise, you will
need to use equivalent packaging materials.
• Some connection cables contain resistors. Do not use cables that
incorporate resistors for connecting to this unit. The use of such
cables can cause the sound level to be extremely low, or impossible
to hear. For information on cable specifications, contact the man-
ufacturer of the cable.
• Use only the specified footswitches pedal (Roland DP-series, BOSS
FS-5U; sold separately). By connecting any other footswitches, you
risk causing malfunction and/or damage to the JM-8.
About the video and touch screen
• In order to provide the highest possible image quality, the JM-8
uses a TFT liquid crystal display. Due to the nature of a TFT liquid
crystal display, the screen may contain pixels that fail to light or
that remain constantly lit, but please be aware that this is not a
malfunction or defect.
• Wipe off stains on the touch screen using ethanol, but do not
allow the ethanol to soak into the joint of the upper fume and the
bottom glass, for it may otherwise cause peeling or malfunction.
Do not use organic solvents or detergents other than ethyl alcohol
(ethanol).
Storage devices that can be connected to the
JM-8's EXTERNAL MEMORY port
• The JM-8 allows you to connect commercially available storage
devices, like USB Flash memory, and hard disks. You can purchase
such devices at a computer store, a digital camera dealer, etc.
• Though hard disks with a capacity in excess of 120GB can be used,
please bear in mind that the JM-8 can manage a maximum of
120GB. (FAT-32 formatted storage devices can be used right
away.)
Before using external USB storage devices
• Use USB memory sold by Roland. We cannot guarantee operation
if any other USB memory is used.
