WARNING
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
When Installing the Unit
• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing
so may result in fire or electric shock.
• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may
result in fire or electric shock.
• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power cord
in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power cord, as
doing so may result in fire or electric shock.
•
Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface.
Doing so may result in the unit falling down and causing personal injury and/or property damage.
• The apparatus shall be connected to a mains socket outlet with a protective earthing connection.
• The socket-outlet shall be installed near the equipment and the plug (disconnecting device) shall be easily
accessible.
When the Unit is in Use
• Should the following irregularity be found during use, immediately switch off the power, disconnect the power
supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the
unit in this condition as this may cause fire or electric shock.
· If you detect smoke or a strange smell coming from the unit
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If the power supply cord is damaged (exposure of the core, disconnection, etc.)
· If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components
inside the unit. Refer all servicing to your nearest TOA dealer.
• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally
spill into the unit, this may cause a fire or electric shock.
•
Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit's cover, as this
may result in fire or electric shock.
