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 condi-
tioner), 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.

 

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.

 

304a

 

• 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.

 

307

 

• Before connecting this unit to other devices, turn off 

the power to all units. This will help prevent malfunc-
tions 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 

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.

 

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 impreg-
nated with a mild, non-abrasive detergent. After-
wards, 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. 
Important data should always be backed up on your 
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.

 

503

 

• If the unit's power is not turned on for several days the 

contents of certain items you've set, such as the date 
and time, will be lost.
