NOTICE
To avoid the possibility of malfunction/damage to the product or
damage to other property, follow the notices below.
 Handling and maintenance
• Do not expose the product to excessive dust or vibration,
or extreme cold or heat, in order to prevent the possibility
of panel disfiguration, unstable operation, or damage to
the internal components.
• Do not touch the speaker driver unit, since it might cause
malfunction.
• Be sure to observe the amplifier's rated load impedance
(see page 108), particularly when connecting speakers in
parallel. Connecting an impedance load outside the ampli-
fier's rated range can damage the amplifier.
• When cleaning the product, use a dry and soft cloth. Do
not use paint thinners, solvents, cleaning fluids, or chemi-
cal-impregnated wiping cloths, since this might cause
alteration or discoloration.
• Air blowing out of the bass reflex ports (hole or holes at the
front) is normal, and often occurs when the speaker is han-
dling program material with heavy bass content.
• Do not place the speaker face down.
 Protective Circuit
• All full-range loudspeakers are fitted with a self-resetting
poly switch that protects the high-frequency driver from
damage caused by excessive power. If a loudspeaker
cabinet loses high-frequency output, immediately remove
power from the power amplifier and wait for two to three
minutes. This should be long enough to allow the poly
switch to reset. Reapply power and check the perfor-
mance of the high-frequency driver before continuing, with
the power reduced to a level that does not cause the poly
switch to interrupt the signal.
