radiate heat, leave it inside an enclosed vehicle, or otherwise subject
it to temperature extremes. Excessive heat can deform or discolor
the unit.
355b
• When moved from one location to another where the temperature
and/or humidity is very di erent, water droplets (condensation)
may form inside the unit. 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.
358

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 on a computer, 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.
