Caution

■ Read the following before using these speakers:

• To assure the finest performance, please read
this manual carefully. Keep it in a safe place
for future reference.

• Install the speakers in a cool, dry, clean place
away from windows, heat sources, sources of
excessive vibration, dust, moisture and cold.
Avoid sources of humming (transformers,
motors). To prevent fire or electric shock, do
not expose the speakers to dripping or
splashing.

• To prevent the enclosure from warping or
discoloring, do not place the speakers where
they will be exposed to direct sunlight or
excessive humidity.

• Do not place the following objects on top of
the speakers:

1. Glass, china, etc.

If glass etc. falls by vibrations and breaks,
it may cause personal injury.

2. A burning candle etc.

If the candle falls by vibrations, it may
cause fire and personal injury.

3. A vessel with water in it

If the vessel falls by vibrations and water
spills, it may cause damage to the unit, and/
or you may get an electric shock.

• Do not place the speakers where foreign
objects such as water drips might fall. It might
cause a fire, damage to this unit, and/or
personal injury.

• Do not place the speakers where they are liable
to be knocked over or struck by falling objects.
Stable placement will also ensure better sound
performance.

• Secure placement or installation is the owner’s
responsibility. Yamaha shall not be liable for
any accident caused by improper placement or
installation of speakers.

• Any time you note distortion, reduce the
volume of your amplifier immediately. Make
sure the input power does not exceed the
specified maximum input power, otherwise the
speakers will be damaged.

• Do not attempt to clean the speakers with
chemical solvents as this might damage the
finish. Use a clean, dry cloth.

• Do not attempt to modify or fix the speakers.
Contact qualified Yamaha service personnel
when any service is needed. The cabinet
should never be opened for any reasons.

Note:

This speaker is magnetically shielded, but placing
them too close to a TV may impair the TV picture. If
this happens, move the speaker away from the TV.

Notes:

• Do not place the speaker on top of the TV whose
area is smaller than the bottom area of the speaker.
If placed, the speaker may drop out causing an
injury to you.

• Do not place the speaker on top of the TV with an
inclination.

• Do not touch the adhesive surface after peeling off
the seal as this will weaken its adhesive strength.

• Thoroughly wipe clean the surface where the
fastener is to be applied. Note that adhesive
strength is weakened if the surface is dirty, oily or
wet and that this may cause the center speaker to
drop.

■ Mounting the speaker NS-C225 on the wall

The speaker can be mounted on a wall by using
the bracket attached to the speaker’s back panel.

surface material, as the screws may come out
of the flimsy surface, causing the speakers to
fall down and be damaged, or result in
personal injury.

• Do not fasten the speakers to wall with nails,
adhesives, or other unsound hardware. Long
term use and vibrations may cause them to fall
down.

• To avoid accidents resulting from tripping

Mode d’emploi

SYSTEME D’ENCEINTES

Nous vous remercions d’avoir opté pour le système d’enceintes de Yamaha.

Prècautions

■ Lisez ces précautions attentivement avant d’utiliser votre enceinte:

• Pour garantir les meilleures performances

possibles, lire ce manuel avec attention. Le
garder dans un endroit sûr pour une utilisation
ultérieure.

• Installer cette enceinte dans un endroit frais,

sec et propre, loin de fenêtres, sources de
chaleur et d’endroits où les vibrations, la
poussière, l’humidité ou le froid sont
importants. Eviter les sources de
bourdonnements (transformateurs, moteurs).
Pour éviter les risques d’incendie ou
d’électrocution, tenez les enceintes à l’écart de
tout liquide et de toute source d’éclaboussures.

• Pour éviter que le coffret se gondole ou se

décolore, ne pas placer l’enceinte à un endroit
ou elle sera exposée aux rayons directs du
soleil ou à une trop forte humidité.

• Ne posez jamais les objets suivants au-dessus

des enceintes:

1. Verres, porcelaine, etc.

Si les verres, etc., tombent sous l’effet des
vibrations et se rompent, ceci risque de
causer des blessures.

2. Une bougie allumée, etc.

Si la bougie tombe sous l’effet des
vibrations, ceci risque de causer un
incendie et des blessures.

3. Un récipient contenant de l’eau

Si le récipient tombe sous l’effet des
vibrations et que l’eau se répand, ceci
risque d’endommager l’appareil et/ou de
causer une électrocution.

• Ne pas placer l’appareil dans un endroit où des
corps étrangers comme des gouttes d’eau
peuvent tomber à l’intérieur. Ceci peut causer
un incendie, des dommages à l’appareil et/ou
une blessure corporelle.

• Ne pas placer l’enceinte à un endroit où elle
risque d’être renversée ou percutée par des
objets tombants. Un endroit bien stable
améliorera aussi la qualité du son.

• Le propriétaire du système est entièrement
responsable du bon positionnement et de la
bonne installation du système. YAMAHA
décline toute responsabilité en cas d’accident
causé par un positionnement ou une
installation inadéquats de l’enceinte.

• Si vous remarquez que le son sature, diminuez
immédiatement le volume sur l’amplificateur.
Vérifiez que la puissance d’entrée ne dépasse
pas la puissance d’entrée maximum spécifiée,
faute de quoi les enceintes seront
endommagées.

• Ne pas essayer de nettoyer cette enceinte avec
des diluants chimiques, ceci endommagerait le
fini. Utiliser un chiffon propre et sec.

• Ne pas essayer de modifier ni de réparer
l’enceinte. Contacter un dépanneur YAMAHA
qualifié en cas de nécessité de réparation. Le
coffret ne doit jamais être ouvert pour quelque
raison que ce soit.

Remarque:

Bien que ce système d’enceintes comporte un blindage
magnétique, il pourrait provoquer une distorsion de
l’image si vous le placez trop près d’un téléviseur.
Dans ce cas, éloignez les enceintes du téléviseur.
