English

-  To reduce the risk of electric 

shock, disconnect the loudspeaker 
from the AC mains before installing 
audio cable. Reconnect the power 
cord only after making all signal 
connections. 

-  Connect the loudspeaker to a 

two-pole, three-wire grounding 
mains receptacle. The receptacle 
must be connected to a fuse or 
circuit breaker. Connection to any 
other type of receptacle poses a 
shock hazard and may violate local 
electrical codes. 

-  Do not install the loudspeaker 

in wet or humid locations 
without using weather protection 
equipment from Meyer Sound.

-  Do not allow water or any 

foreign object to get inside the 
loudspeaker. Do not put objects 
containing liquid on or near the 
unit.

-  To reduce the risk of overheating 

the loudspeaker, avoid exposing it 
to direct sunlight. Do not install the 
unit near heat-emitting appliances, 
such as a room heater or stove. 

-  This loudspeaker contains 

potentially hazardous voltages. Do 
not attempt to disassemble the 
unit. The unit contains no user-
serviceable parts. Repairs should 
be performed only by factory-
trained service personnel.

Français

-  Pour réduire le risque 

d’électrocution, débrancher 
la prise principale de l’haut-
parleur, avant d’installer le câble 
d’interface allant à l’audio. Ne 
rebrancher le bloc d’alimentation 
qu’après avoir effectué toutes les 
connections.

-  Branchez l’haut-parleur dans une 

prise de courant à 3 dérivations 
(deux pôles et la terre). Cette 
prise doit être munie d’une 
protection adéquate (fusible ou 
coupe-circuit). Le branchement 
dans tout autre genre de prise 
pourrait entraîner un risque 
d’électrocution et peut constituer 
une infraction à la réglementation 
locale concernant les installations 
électriques.

-  Ne pas installer l’haut-parleur dans 

un endroit où il y a de l’eau ou une 
humidité excessive.

-  Ne pas laisser de l’eau ou tout 

objet pénétrer dans l’haut-parleur. 
Ne pas placer de r´cipients 
contenant un liquide sur cet 
appareil, ni à proximité de celui-ci.

-  Pour éviter une surchauffe de 

l’haut-parleur, conserver-la à 
l’abri du soleil. Ne pas installer à 
proximité d’appareils dégageant 
de la chaleur tels que radiateurs 
ou appareils de chauffage.

-  Ce haut-parleur contient des 

circuits haute tension présentant 
un danger. Ne jamais essayer 
de le démonter. Il n’y a aucun 
composant qui puisse être 
réparé par l’utilisateur. Toutes les 
réparations doivent être effectuées 
par du personnel qualifié et agréé 
par le constructeur.

Deutsch

-  Um die Gefahr eines elektrischen 

Schlages auf ein Minimum zu 
reduzieren, den Lautsprecher 
vom Stromnetz trennen, bevor 
ggf. ein Audio-Schnittstellensign
alkabel angeschlossen wird. Das 
Netzkabel erst nach Herstellung 
aller Signalverbindungen wieder 
einstecken.

-  Der Lautsprecher an eine 

geerdete zweipolige Dreiphasen-
Netzsteckdose anschließen. 
Die Steckdose muß mit einem 
geeigneten Abzweigschutz 
(Sicherung oder Leistungsschalter) 
verbunden sein. Der Anschluß 
der unterbrechungsfreien 
Stromversorgung an einen 
anderen Steckdosentyp kann 
zu Stromschlägen führen und 
gegen die örtlichen Vorschriften 
verstoßen. 

-  Der Lautsprecher nicht an einem 

Ort aufstellen, an dem sie mit 
Wasser oder übermäßig hoher 
Luftfeuchtigkeit in Berührung 
kommen könnte.

-  Darauf achten, daß weder 

Wasser noch Fremdkörper in 
das Innere den Lautsprecher 
eindringen. Keine Objekte, die 
Flüssigkeit enthalten, auf oder 
neben die unterbrechungsfreie 
Stromversorgung stellen.

-  Um ein Überhitzen dem 

Lautsprecher zu verhindern, 
das Gerät vor direkter 
Sonneneinstrahlung fernhalten 
und nicht in der Nähe von 
wärmeabstrahlenden 

 

Haushaltsgeräten (z.B. Heizgerät 
oder Herd) aufstellen. 

-  Im Inneren diesem Lautsprecher 

herr-schen potentiell gefährliche 
Spannungen. Nicht versuchen, 
das Gerät zu öffnen. Es 
enthält keine vom Benutzer 
reparierbaren Teile. Reparaturen 
dürfen nur von ausgebildetem 
Kundenienstpersonal durchgeführt 
werden.

Español

-  Para reducir el riesgo de descarga 

eléctrica, desconecte de la red 
de voltaje el altoparlante antes de 
instalar el cable de señal de audio. 
Vuelva a conectar la alimentacion 
de voltaje una vez efectuadas 
todas las interconexiones de 
señalizacion de audio.

-  Conecte el altoparlante a un 

tomacorriente bipolar y trifilar 
con neutro de puesta a tierra. 
El tomacorriente debe estar 
conectado a la protección de 
derivación apropiada (ya sea 
un fusible o un disyuntor). La 
conexión a cualquier otro tipo de 
tomacorriente puede constituir 
peligro de descarga eléctrica 
y violar los códigos eléctricos 
locales. 

-  No instale el altoparlante en 

lugares donde haya agua o 
humedad excesiva. 

-  No deje que en el altoparlante 

entre agua ni ningún objeto 
extraño. No ponga objetos con 
líquidos encima de la unidad ni 
cerca de ella. 

-  Para reducir el riesgo de 

sobrecalentamiento, no exponga 
la unidad a los rayos directos del 
sol ni la instale cerca de artefactos 
que emiten calor, como estufas o 
cocinas. 

-  Este altoparlante contiene 

niveles de voltaje peligrosos en 
potencia. No intente desarmar la 
unidad, pues no contiene piezas 
que puedan ser repardas por el 
usuario. Las reparaciones deben 
efectuarse únicamente por parte 
del personal de mantenimiento 
capacitado en la fábrica.
