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. Roland assumes no liability concerning 
such loss of data.
Additional Precautions
•  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.
•  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.
•  When 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 others nearby, try to keep the 
unit’s volume at reasonable levels. You may prefer 
to use headphones, so you do not need to be 
concerned about those around you.
•  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 information on cable 
specications, contact the manufacturer of the 
cable.
