IMPORTANT SAFETY INSTRUCTIONS

· Be sure to read the instructions in this section carefully before use.

· Make sure to observe the instructions in this manual as the safety messages regarded as very important

precautions are included.

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

Do not block any ventilation openings.

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.

Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades

with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide

blade or the third prong is provided for your safety. When the provided plug does not fit into your outlet,

consult an electrician for replacement of the obsolete outlet.

Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

Only use the attachments or accessories specified by the manufacturer.

Use only with a 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. SAFETY PRECAUTIONS

Be sure to read the instructions in this section carefully before use.

Make sure to observe the instructions in this manual as the conventions of safety symbols and messages

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

CAUTION

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 property

damage.

WARNING

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 70 V is applied to the high impedance speaker

terminals, never touch these terminals to avoid

electric shock.

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 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.

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.

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.

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 power supply plug during thunder and lightning, as this may result in electric shock.
