IMPORTANT NOTES
Power Supply: Use of Batteries
¢ 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).
«Since the ME-30 consumes a considerable'amount of
power, we recommend the use of an AC adaptor. Be sure
to use only the specified AC adaptor, and connect it only to
outlets delivering the specified voltage. For battery-pow-
ered operation, we recommend that you use alkaline
batteries.
* 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.

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 written down on paper. 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 con-
cerning such loss of data.
Additional Precautions
¢Piease be aware that the contents of memory can be
irretrievably lost as a result of a malfunction, or the im-
proper operation of the unit. To protect yourself against the
risk of loosing important data, we recommend that you
periodically save a backup copy of important data you have
stored in the unit's memory on a paper
© Unfortunately, it may be impossible to restore the contents
of data that was stored 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 internal
elements.
* 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).
© 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.
When using an AC adaptor (PSA Series; optional),
please also observe the following precautions.
* The AC adaptor will begin to generate heat after long hours
of consecutive use. This is normal, and 'is not a cause for
concern.
