Boss Audio Systems ME-50B User Manual

 

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.

 

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.

 

306b

 

• Batteries are supplied with the unit. The life of these 

batteries may be limited, however, since their primary 
purpose was to enable testing.

 

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 inter-
ference.

 

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 initi-
ating 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.

 

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. 
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.

 

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 protect yourself against 
the risk of loosing important data, we recommend that 
important data should always be written down on paper.

 

552

 

• 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.

 

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.

 

554

 

• Never strike or apply strong pressure to the display.

 

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.

 

558a

 

• To avoid disturbing your neighbors, 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 (especially when it is late at night).

 

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.

 

562

 

• Use a cable from Roland to make the connection. If using 

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

• 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.
