EM-50/30
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY”,
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).
Be sure to only use the supplied adapter (Roland ACJ).
The use of other adapters may damage your EM-50/30.
Before connecting the EM-50/30 to other devices, turn
off the power to all units. This will help prevent malfunc-
tions and/or damage to speakers or other devices.
Placement
Using the EM-50/30 near power amplifiers (or other
equipment containing large power transformers) may
induce hum. To alleviate the problem, change the orien-
tation of this instrument or move it farther 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.
Do not expose the EM-50/30 to direct sunlight, place it
near devices that radiate heat, leave it inside an enclosed
vehicle, or otherwise subject it to temperature extremes.
Excessive heat can deform or discolor the instrument.
Maintenance
For everyday cleaning wipe the EM-50/30 with a soft, dry
cloth or one that has been slightly dampened with water.
To remove stubborn dirt, use a mild, non-abrasive deter-
gent, Afterwards, be sure to wipe the instrument thor-
oughly 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 instru-
ment's memory may be lost when it is sent for repairs.
Important data should always be saved to floppy disk
(EM-50 only). 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 irre-
trievably lost as a result of a malfunction, or the improp-
er operation of the instrument. To protect yourself
against the risk of losing important data, we recommend
that you periodically make a backup copy of your set-
tings by saving them to a floppy disk (EM-50 only) or via
MIDL
Use a reasonable amount of care when using the instru-
ment'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 all cables, grasp the con-
nector 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 normal operation. This is perfectly normal.
To avoid disturbing your neighbors, try to keep the
instrument'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 instrument, package it
in the box (including padding) that it came in. Other-
wise, you will need to use eguivalent packaging materials,
or a flightcase.
