IMPORTANT NOTES

Power Supply

301
●
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.
302
●
The AC adaptor will begin to generate heat after long hours of
consecutive use. This is normal, and is not a cause for concern.
307
●
Before connecting this unit to other devices, turn off the
power to all units. This will help prevent malfunctions and/or
damage to speakers or other devices.
309
●
With the factory settings, the M-200i's power will automati-
cally be switched off 8hours after you stop playing or
operating the unit.If you don't want the power to turn off
automatically, change the "AUTO POWER OFF" setting to
"OFF" as described on p.111
The settings you were editing will be lost when the power is
turned off. If you want to keep your settings, you must save
your settings before turning the power off.
Placement
351
●
Using the unit near power amplifiers (or other equipment
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 interference.
352a
●
This device may interfere with radio and television reception.
Do not use this device in the vicinity of such receivers.
352b
●
Noise may be produced if wireless communications devices,
such as cell phones, are operated in the vicinity of this unit.
Such noise could occur when receiving or initiating a call, or
while conversing. Should you experience such problems, you
should relocate such wireless devices so they are at a greater
distance from this unit, or switch them off.
354a
●
Do not expose the unit to direct sunlight, place it near devices
that 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 temper-
ature 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.
360
●
Depending on the material and temperature of the surface on
which you place the unit, its rubber feet may discolor or mar
the surface.
You can place a piece of felt or cloth under the rubber feet to
prevent this from happening. If you do so, please make sure
that the unit will not slip or move accidentally.

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. Important data
should always be backed up
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.
