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).
● 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 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 recep-
tion. 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 benzene, 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 mem-
ory may be lost when the unit is sent for repairs.
Important data should always be backed up on a RAM
card/DATA card, 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 dealer, or qualified
Roland service personnel.

Additional Precautions
● Please be aware that the contents of memory can be irre-
trievably lost as a result of a malfunction, or the improper
operation of the unit. To protect yourself against the risk
of loosing important data, we recommend that you peri-
odically save a backup copy of important data you have
stored in the unit’s memory on a RAM card/DATA card,
in another MIDI device (e.g., a sequencer).
● Unfortunately, it may be impossible to restore the con-
tents of data that was stored on a RAM card/DATA card,
in another MIDI device (e.g., a sequencer), in the unit’s
memory 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 malfunctions.
● 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.
● A small amount of heat will radiate from the unit during
normal operation.
● To avoid disturbing your neighbors, try to keep the unit’s
volume at reasonable levels. You may prefer to use head-
phones, so you do not need to be concerned about those
around you (especially when it is late at night).
● Since sound vibrations can be transmitted through floors
and walls to a greater degree than expected, take care not
to allow such sound to become a nuisance to neighbors,
especially at night and when using headphones.
Although the drum pads and pedals are designed so
there is a minimal amount of extraneous sound produced
when they're struck, rubber heads tend to produce louder
sounds compared to mesh heads. You can effectively
reduce much of the unwanted sound from the pads by
switching to mesh heads.
● 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.
● Use a cable from Roland to make the connection. If using
some other make of connection cable, please note the fol-
lowing precautions.
❍ 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 infor-
mation on cable specifications, contact the manufactur-
er of the cable.
Before Using Cards
Using DATA Cards
● New M-512E DATA cards do not yet have their battery
installed. Before a DATA card can be used, you first need
to insert the battery (refer to the instructions supplied
with the DATA card).
● M-512E DATA cards are equipped with a PROTECT
switch, which when turned on protects your data from
accidental erasure. It is recommended that the switch be
kept at the ON position, and switched to OFF only at the
times you wish to write new data onto the card.
● When the battery in an M-512E DATA card is nearly
worn out, the message below will be shown in the dis-
play. Refer to the instructions supplied with the DATA
card and promptly replace the battery to avoid the loss of
the data on it.
“MEMORY CARD Battery Low ! Please Change !”
● Carefully insert the DATA card all the way in—until it is
firmly in place.
● Never touch the terminals of the DATA card. Also, avoid
getting the terminals dirty.
