• Do not expose the unit to rain or an environment
where it may be splashed by water or other liquids,
asdoingsomayresultinreorelectricshock.
• Use the unit only with the voltage specied on
theunit.Usingavoltagehigherthanthatwhichis

• Do not cut, kink, otherwise damage nor modify
thepowersupplycord.Inaddition,avoidusingthe
powercordincloseproximitytoheaters,andnever
placeheavyobjects--includingtheunititself--on
the power cord, as doing so may result in re 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
downandcausingpersonalinjuryand/orproperty
damage.
• Since the unit is designed for indoor use, do not
install it outdoors. When it gets wet, there is a
danger of electric shock.
• Theapparatusshallbeconnectedtoamainssocket
outletwithaprotectiveearthingconnection.
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
maycausereorelectricshock.
· 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
· Ifthepowersupplycordisdamaged(exposureof
thecore,disconnection,etc.)
· If it is malfunctioning.
• To prevent a re or electric shock, never open

When Installing the Unit
• Never plug in nor remove the power supply plug
with wet hands, as doing so may cause electric
shock.
• Whenunpluggingthepowersupplycord,besureto
graspthepowersupplyplug;neverpullonthecord
itself. Operating the unit with a damaged power
supplycordmaycauseareorelectricshock.
• The socket-outlet shall be installed near the
equipment and the plug (disconnecting device)
shall be easily accessible.
• Whenmovingtheunit,besuretoremoveitspower
supply cord from the wall outlet. Moving the unit
with the power cord connected to the outlet may

sure to hold its plug to pull.
• Avoidinstallingtheunitinhumidordustylocations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke
or steam as doing otherwise may result in re or
electric shock.
When the Unit is in Use
• Makesurethatthevolumecontrolissettominimum
position before power is switched on. Loud noise
producedat high volume when poweris switched
on can impair hearing.
• UsethespeciedACadapterfortheunit.Notethat

• If dust accumulates on the power supply plug or
in the wall AC outlet, a re may result. Clean it
periodically. In addition, insert the plug in the wall
outlet securely.
