be damaged by excessive vibration, potentially
causing the speaker to fall, which could result in
personal injury.
Do not use anti-rust lubricant. If it contacts resin or
rubber parts, they could deteriorate and cause the
speaker to fall, possibly resulting in personal injury.
Do not install the speaker in indoor swimming
pools or such locations where liquid chemicals are
used. The parts deteriorate if corroded, causing
the speaker to fall, which could result in personal
injury.
When the Unit is in Use
If any of the following irregularities occurs,
immediately switch off the amplifier's power, and
inform the shop from where the speaker was
purchased. Further using the speaker may result in
fire or electric shock.
· If you detect smoke or a strange smell coming
from the speaker
· If water or any metallic object gets into the
speaker
· If the speaker falls, or the speaker case breaks
To prevent a fire or electric shock, never open nor
remove the speaker case. Refer all servicing to
your nearest TOA dealer.
When Installing the Unit
Avoid touching the speaker's sharp metal edge
to prevent injury.
To avoid electric shocks, be sure to switch off
the
amplifier's
power
when
connecting
speakers.
When the Unit is in Use
Do not operate the speaker for an extended period
of time with the sound distorting. Doing so may
cause the speaker to heat, resulting in a fire.
Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property
damage.
Have the speaker checked periodically by the shop
from where it was purchased. Failure to do so may
result in corrosion or damage to the speaker or the
mounts that could cause it to fall, possibly causing
personal injury.
