When Installing the Unit

• Refer all installation work to the dealer from whom the speaker was purchased. Installation work requires
extensive technical knowledge and experience. The speaker may fall off if incorrectly installed, resulting in
possible personal injury.

• Install the speaker only in a location that can structurally support the weight of the speaker. Doing otherwise
may result in the speaker falling down and causing personal injury and/or property damage.

• Since the speaker is designed for in-door use, do not install it outdoors. If installed outdoors, the aging of
parts causes the speaker to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a
danger of electric shock.

• Do not use other methods than specified to install the speaker. Extreme force is applied to the speaker and
the speaker could fall off, possibly resulting in personal injuries.

• Attach the safety wire to the speaker. If not attached, the speaker could fall off, resulting in personal injury.

• Use screws that are appropriate for the ceiling's or wall's material and structure. Failure to do so may cause
the speaker to fall, resulting in material damage and possible personal injury.

• Ensure that all screws are securely tightened. If they are loose after installation, the speaker could fall down,
possibly resulting in personal injury.

• Do not mount the speaker in locations exposed to constant vibration. The speaker or its mounts can be
damaged by excessive vibration, potentially causing the speaker to fall, which could result in personal injury.

• Avoid installing the speaker in locations exposed to sea breeze or corrosive gas. The speaker or its parts
may be subject to corrosion, that might cause it to fall or result 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.

• Do not install the speaker in kitchens or such locations where grease or oily smoke is generated. Failure to
follow this instruction could deteriorate the speaker mounting parts, 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

• Never install the speaker in humid or dusty locations, in locations exposed to direct sunlight, or near heaters
as doing otherwise may result in fire or electric shock.

• To avoid electric shocks, be sure to switch off the amplifier's power when connecting speakers.

• The speaker front and rear cases are secured with adhesive tape (2 points) at both sides when shipped from
the factory. Remove the tapes while placing the speaker on a stable surface or while supporting it with hand.
Failure to do so may cause the case to fall, resulting in material damage and possible personal injury.

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.

Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
