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.
