IMPORTANT NOTES

 

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.

 

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.

 

401a

 

 

For everyday cleaning wipe the unit with a soft, dry cloth or 
one that has been slightly dampened with water. To remove 
stubborn dirt, use a cloth impregnated with a mild, non-
abrasive detergent. Afterwards, be sure to wipe the unit 
thoroughly with a soft, dry cloth.

 

402

 

 

Never use benzine, thinners, alcohol or solvents of any kind, to 
avoid the possibility of discoloration and/or deformation.

 

452

 

 

Please be aware that all data contained in the unit’s memory 
may be lost when the unit is sent for repairs. Please save 
important data as a file on the M-400 or on your computer. For 
details on how to save data, refer to the owner’ manual of the 
M-400 (Ver. 2.0 or later) or the S-4000 RCS Ver. 2.0. 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.

 

551

 

 

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. To avoid inconvenience in the event of 
data loss, save important data as a file on the M-400 or on your 
computer. For details on how to save data, refer to the owner’s 
manual of the M-400 (Ver. 2.0 or later) or the S-4000 RCS 
Ver. 2.0.

 

552

 

 

Unfortunately, it may be impossible to restore the contents of 
data that was stored on the unit, the M-400, and your 
computer once it has been lost. Roland Corporation assumes 
no liability concerning such loss of data.

 

553

 

 

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.

 

556

 

 

When connecting / 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.

 

559a

 

 

When you need to transport the unit, package it in the box 
(including padding) that it came in, if possible. Otherwise, you 
will need to use equivalent packaging materials.
