 VPrecautions for use
 oDo not install this unit in a location that could become hot. 
This includes places that are exposed to direct sunlight or near 
a radiator, heater, stove or other heating equipment. Moreover, 
do not place it on top of an amplifier or other equipment that 
generates heat. Doing so could cause discoloration, deformation 
or malfunction.
 oAvoid locations that are extremely cold or exposed to excessive 
humidity or dust.
 oWhen installing this unit, leave a little space (at least 3 cm or 8") 
between it and walls and other devices in order to allow good 
heat dissipation. If you put it in a rack, for example, leave at least 
5 cm (2") open above it and at least 10 cm (4") open behind it. 
Failure to provide these gaps could cause heat to build up inside 
and result in fire.
 oPlace the unit in a stable location near the audio system that you 
will use with it.
 oDO NOT place anything, not even CDs, CD-Rs, LP records or cas-
sette tapes, on top of the units. Doing so could cause damage.
 oThe voltage supplied to the unit should match the voltage 
printed on the rear panel. If you are in any doubt regarding this 
matter, consult an electrician.
 oDo not move the unit during use.
 oDo not open the body of the unit because this could result in 
damage to the circuitry or cause electric shock. If a foreign object 
should enter the unit, contact your dealer.
 oWhen removing the power plug from the wall outlet, always pull 
directly on the plug; never yank on the cord.
Wipe dirt from the top cover and other panel surfaces using a 
soft cloth that has been slightly dampened with a diluted neutral 
cleanser.
Do not wipe with chemical cleaning cloths, thinner or other chemi-
cal agents. Doing so could damage the surface.
 VFor your safety, disconnect the power cord from 
the socket before cleaning.

Deshacerse de aparatos eléctricos, electrónicos, 
pilas/baterías y acumuladores
a)  Todos los aparatos eléctricos y electrónicos, y pilas/baterías y 
acumuladores gastados, deben ser eliminados separados del 
resto de basura común y únicamente en los “puntos limpios” 
o bajo los procedimientos especificados por el gobierno o 
autoridades municipales locales.
b)  Con la eliminación correcta de los equipos eléctricos y elec-
trónicos, y de pilas/baterías y acumuladores gastados, estará 
ayudando a conservar recursos muy valiosos y a evitar los 
posibles efectos negativos en la salud humana y en el medio 
ambiente.
c)  La eliminación incorrecta de los equipos eléctricos y electró-
nicos, y pilas/baterías y acumuladores, puede producir 
efectos muy dañinos en el medio ambiente y en la salud 
humana a causa de las sustancias peligrosas que pueden 
encontrarse en estos equipos.
d)  El símbolo de Eliminación de Aparatos Eléctricos y 
Electrónicos (WEEE en inglés), identificado por cubos 
de basura con ruedas tachados, indican que los equi-
pos eléctricos y electrónicos, y las pilas/baterías y 
acumuladores, deben ser eliminados de forma total-
mente independiente con respecto a la basura doméstica.
Si una pila/batería o un acumulador contienen más 
cantidad de los valores especificados de plomo (Pb), 
mercurio (Hg), y/o cadmio (Cd) según está definido 
en la Directiva relativa a las pilas (2006/66/EC), enton-
ces los símbolos químicos correspondientes a estos 
elementos estarán indicados debajo del símbolo WEEE.
e)  Existen sistemas para la eliminación y recogida a disposición 
del usuario final. Si necesita más información sobre cómo 
deshacerse de aparatos eléctricos y electrónicos antiguos, así 
como de pilas/baterías y acumuladores, póngase en contacto 
con su ayuntamiento, con la correspondiente empresa del 
servicio de recogida de residuos o con el establecimiento 
donde adquirió ese aparato.
