• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages
regarded as very important precautions are included.

• 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.

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.

• 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.

• Avoid touching the unit's sharp metal edge to prevent injury.
