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
the unit thoroughly with a soft, dry cloth.

memory may be lost when the unit is sent for repairs.
Important data should always be 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.
303a
• The use of an AC adaptor is recommended as the unit’s
power consumption is relatively high. Should you prefer
to use batteries, please use the alkaline type.

• When installing or replacing batteries, always turn off the
power on this unit and disconnect any other devices you
may have connected. This way, you can prevent
malfunction and/or damage to speakers or other devices.

• Unfortunately, it may be impossible to restore the contents
of data that was stored in the unit’s memory once it has
been lost. BOSS/Roland Corporation assumes no liability
concerning such loss of data.
Placement

• Using the unit near power amplifiers (or other equipment
553
containing large power transformers) may induce hum.
To alleviate the problem, change the orientation of this
unit; or move it farther away from the source of inter-

• When connecting / disconnecting all cables, grasp the
reception. Do not use this device in the vicinity of such
connector itself—never pull on the cable. This way you
will avoid causing shorts, or damage to the cable’s
receivers.

some other make of connection cable, please note the
following precautions.
355b
• 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.
• 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.
