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.
2. SAFETY PRECAUTIONS

manufacturer.
• Use only with the cart, stand, tripod, bracket, or
table specified by the manufacturer, or sold with
the apparatus.
• When a cart is used, use
caution when moving the
cart/apparatus combination to
avoid injury from tip-over.
• Unplug this apparatus during lightning storms or
when unused for long periods of time.
• Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally, or has been dropped.
1. IMPORTANT SAFETY INSTRUCTIONS
WARNING
• The terminals marked with the symbol are
hazardous live. The external wiring to these
terminals requires installation by an instructed
person.
• The apparatus shall be connected to a mains
socket outlet with a protective earthing connection.
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
you 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.
When Installing the Unit
• Never plug in nor remove the power supply plug
with wet hands, as doing so may cause electric
shock.
• When unplugging the power supply cord, be sure
to grasp the power supply plug; never pull on the
cord itself. Operating the unit with a damaged
power supply cord may cause a fire or electric
shock.
• Do not block the ventilation slots in the unit's cover.
Doing so may cause heat to build up inside the unit
and result in fire.
• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.
• To avoid electric shocks, be sure to unplug the
unit's power supply cord when connecting
speakers.
• Be sure to follow the instructions below when rackmounting the unit. Failure to do so may cause a fire
or personal injury.
· Install the equipment rack on a stable, hard floor.
Fix it with anchor bolts or take other arrangements
to prevent it from falling down.
· When connecting the unit's power cord to an AC
outlet, use the AC outlet with current capacity
allowable to the unit.
· No rack-mounting screws are supplied with the
unit. Separately prepare the appropriate screws
for the rack.
• Keep the A-230 amplifier over 10 cm away from
objects that may obstruct air flow to prevent the
unit's internal temperature rise.
When the Unit is in Use
• Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
• Switch off the power, and unplug the power supply
plug from the AC outlet for safety purposes when
cleaning or leaving the unit unused for 10 days or
more. Doing otherwise may cause a fire or electric
shock.
The lighting flash with arrowhead symbol,
within an equilateral triangle, is intended
to alert the user to the presence of
uninsulated ''dangerous voltage'' within
the product's enclosure that may be of
sufficient magnitude to constitute a risk of
electric shock to persons.
• L'appareil ne doit pas etre expose aux
eclaboussures ou ecoulements et tous objets
remplis de liquide, tels que vases, ne doivent pas
etre sur I'appareil.
