• Leave the installation to your TOA dealer because the installation requires expert knowledge. Improper
installation may cause the speaker to fall, resulting in personal injury and/or property damage.
• Install the mounting hardware in a location that can structurally support the weight of the mounting hardware
and the speaker. Doing otherwise may result in the speaker falling down and causing personal injury and/or
property damage.
• Do not use other methods than specified to mount the unit. Extreme force is applied to the unit and the unit
could fall off, possibly resulting in personal injuries.
• Use nuts and bolts that are appropriate for the ceiling's or wall's structure and composition. Failure to do so
may cause the speaker to fall, resulting in material damage and possible personal injury.
• Tighten each nut and bolt securely. Ensure that the unit has no loose joints after installation to prevent
accidents that could result in personal injury.
• Use the specified speaker in combination. Doing otherwise may cause the speaker or component to fall off,
resulting in personal injury.
• Do not stand or sit on, nor hang down from the mounting hardware as this may cause it to fall off, resulting in
personal injury and/or property damage.
• Avoid touching the unit's sharp metal edge to prevent injury.
