Consumer Precautions
Read these precautions carefully before operating your
YHT-10 home theater system:
• Since the NS-A76 speakers can be wall mounted, 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 the NS-A76 speakers 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-A76 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-A636 and NS-AC2 speakers feature a
magnetically-shielded design, but there is still a
chance that placing them too close to a TV might
impair picture color. Should this happen, move the
speakers away from the TV.
• 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 R-V502 receiver volume control before
changing input sources. Never change input sources
(for example, FM to CD) at high listening levels.
Always turn the R-V502 receiver unit off when
installing or removing input cables.
• Any time you note distortion, reduce the volume control
on the R-V502 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.
