• Do not connect this unit to same electrical outlet that is
being used by an electrical appliance that is controlled
by an inverter (such as a refrigerator, washing machine,
microwave oven, or air conditioner), or that contains a
motor. Depending on the way in which the electrical
appliance is used, power supply noise may cause this
unit to malfunction or may produce audible noise. If it is
not practical to use a separate electrical outlet, connect a
power supply noise filter between this unit and the
electrical outlet.

• When moved from one location to another where the
temperature and/or humidity is very different, 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.

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 an SD
card, 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.
