• 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.

• The AC adaptor will begin to generate heat after long 

hours of consecutive use. This is normal, and is not a 
cause for concern.

• 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.

• 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.

 

• This device may interfere with radio and television 

reception. Do not use this device in the vicinity of such 
receivers.

• 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.

• 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.

• 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.

• Do not allow objects to remain on top of the keyboard. 

This can be the cause of malfunction, such as keys ceasing 
to produce sound.

 

• 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.

• Never use benzine, thinners, alcohol or solvents of any 

kind, to avoid the possibility of discoloration and/or 
deformation.
