regarded as very important precautions are included.

• We also recommend you keep this instruction manual handy for future reference. 

Safety Symbol and Message Conventions 

Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first so you are
thoroughly aware of the potential safety hazards as well as understand the safety symbols and messages. 

WARNING

Indicates a potentially hazardous situation which, if mishandled,
could result in death or serious personal injury.

Indicates a potentially hazardous situation which, if mishandled,
could result in moderate or minor personal injury, and/or proper
damage.

WARNING

CAUTION

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. 

• Be sure to replace the unit's terminal cover after

connection completion. Because the voltage of up
to 100 V is applied to the output terminals, never
touch these terminals to avoid 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. 

• Install the unit only in a location that can

structurally support the weight of the unit and the
mounting bracket. Doing otherwise may result in
the unit falling down and causing personal injury
and/or property damage.

When the Unit is in Use 

• 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. 

• Do not touch a plug during thunder and lightning,

as this may result in electric shock. 

• 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.)
