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 and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
WARNING Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
CAUTION Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
WARNING
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.
The terminals marked with the symbol are
hazardous live. The external wiring to these
terminals requires installation by an instructed
person.
The socket-outlet shall be installed near the
equipment and the plug (disconnecting device)
shall be easily accessible.
Be sure to replace the unit’s terminal cover
after connection completion. Because the
voltage of up to 100V is applied to the high
impedance speaker terminals, never touch these
terminals to avoid electric shock.
Be sure to ground to the safety ground (earth)
terminal to avoid electric shock. Never ground to
a gas pipe as a catastrophic disaster may result.

If the power supply cord is damaged (expo
sure 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 object or
flammable materialsin the ventilation slots of the
