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.

The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operation and
maintenance (servicing) instruction in the
literature accompanying the appliance.

WARNING

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

When Installing the Unit

• Only use attachments/accessories specified by the
manufacturer.

• Use only with the cart, stand,
tripod, bracket, or table
specified by the
manufacturer, or sold with the
apparatus.

• When a earth 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.

• 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.

• 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.

• The terminals marked with the symbol are

hazardous live. The external wiring to these terminals
requires installation by an instructed person.

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 ease 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.

• 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 2000 series amplifiers over 10 cm away
from objects that may obstruct air flow to prevent the
unit's internal temperature rise.

CAUTION

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

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.

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.

An all-pole mains switch with a contact
separation of at least 3 mm in each pole shall be
incorporated in the electrical installation of the
building.

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.

• 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.
