Repairs and Data
452
●
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 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
501b
●
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 battery
replaced, consult with your retailer, the nearest Roland
Service Center, or an authorized Roland distributor, as
listed on the “Information” page.

●
Please be aware that the contents of memory can be
irretrievably 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 periodically save a backup copy of important data
you have stored in the unit’s memory in another MIDI
device (e.g., a sequencer).

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.

❍
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 manufac-
turer of the cable.
