Consumer Precautions
Read these precautions carefully before operating your
CLS-150 speaker system:
• Since the NS-A425A speakers can be wall mounted for
surround use, it is essential that they are firmly secured.
Be sure to consult a reliable source about the best type
of hanger for your particular wall’s construction. Secure
installation is the purchaser’s responsibility.
• Do not attach them to thin plywood or soft wall
surface materials as the screws may tear free,
causing the speakers to fall and be damaged, or
resulting in personal injury.
• Do not fasten the NS-A425A speakers to walls with
nails, adhesives, or other unsafe hardware. Long-
term use and vibrations may cause them to pull free.
• Do not place any speakers where they are liable to be
knocked over or struck by falling objects. Stable
placement will also ensure better sound performance.
• The NS-A425A speakers feature a magnetically-
shielded design, but there is still a chance that
placing them too close to a TV set might impair
picture color. Should this happen, move the
speakers away from the TV set.
• Placing speakers on the same stand or shelf as a
turntable can result in feedback.
• Never touch the woofer or tweeter units with your
hand or expose them to excessive physical shock. If
they are dented or bent, the sound will be distorted.
• Lower the power amplifier/receiver volume control
before changing input sources. Never change input
sources (for example, FM to CD) at high listening
levels. Always turn the amplifier/receiver unit off
when installing or removing input cables.
• Any time you note distortion, reduce the volume
control on your power amplifier/receiver to a lower
setting. Never allow your power amplifier to be
driven into “clipping.”
• Do not attempt to clean the speakers with chemical
solvents, as this might damage the finish. To clean,
wipe with a dry, soft cloth.
• To prevent the enclosure from warping or discolor-
ing, do not place the speakers where they will be
exposed to direct sunlight or excessive humidity.
