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.
External wiring connected to the terminals marked with requires installation by an instructed person.

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 the power supply cord is damaged (exposure of the core, disconnection, etc.)
If it is malfunctioning (no tone sounds.)

inside the unit. Refer all servicing to your nearest TOA dealer.

To prevent a fire or electric shock, never open or remove the unit case as there are high voltage components

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.

When Installing the Unit

Never plug in or remove the power supply plug with wet hands, as doing so may cause electric shock.
