Notes on speaker use
≥Use only supplied speakers
Using other speakers can damage the unit, and sound quality will be
negatively affected.
≥You can damage your speakers and shorten their useful life if you play
sound at high levels over extended periods.
≥Reduce the volume in the following cases to avoid damage:
– When playing distorted sound.
– When the speakers are reverberating due to a record player, noise
from FM broadcasts, or continuous signals from an oscillator, test
disc, or electronic instrument.
– When adjusting the sound quality.
– When turning the unit on or off.
If irregular coloring occurs on your TV
The center speaker is designed to be used close to a TV, but the picture
may be affected with some TVs and setup combinations.
If this occurs, turn the TV off for about 30 minutes.
The demagnetizing function of the TV should correct the problem. If it
persists, move the speakers further away from the TV.
Caution
≥Do not touch the front netted area of the speakers. Hold by the sides.
e.g. Center speaker
≥Do not stand on the base. Be cautious when children are near.
e.g. [PT754] Front speaker
∫ Attaching to a wall
You can attach all of the speakers (except subwoofer) to a wall.
≥The wall or pillar on which the speakers are to be attached
should be capable of supporting 10 kg (22 Ibs) per screw.
Consult a qualified building contractor when attaching the
speakers to a wall. Improper attachment may result in damage to
the wall and speakers.
1 Drive a screw (not included) into the wall.
2 Fit the speaker securely onto the screw(s) with the hole(s).
∫ Fitting speaker stands (not included)
(Except subwoofer)
Ensure the stands meet these conditions before purchasing them.
Note the diameter and length of the screws and the distance
between screws as shown in the diagram.
≥The stands must be able to support over 10 kg (22 Ibs).
≥The stands must be stable even if the speakers are in a high
position.
e.g. Center speaker
Caution
≥The main unit and supplied speakers are to be
used only as indicated in this setup. Failure to
do so may lead to damage to the amplifier and/
or the speakers, and may result in the risk of
fire. Consult a qualified service person if
damage has occurred or if you experience a
sudden change in performance.
≥Do not attempt to attach these speakers to
walls using methods other than those
described in this manual.
