personal injury, and/or property damage.
• Leave the installation to your TOA dealer because the
installation requires expert knowledge. Improper installation
may cause the unit to fall, resulting in personal injury and/or
property damage.
• Should the following irregularity be found during use,
immediately stop operating the unit and contact your nearest
TOA dealer. Further attempt to use under this condition may
cause fire or electric shock.

• Avoid installing the unit in locations where it may be directly
splashed by sprinklers or by hosing, as doing so may result
in fire or electric shock.
• Do not operate the unit for an extended period of time with
the sound distorting. This is an indication of a malfunction,
which in turn can cause heat to generate and result in a fire.
