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 rst and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

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 re or electric shock.

• Since the unit is designed for indoor use, do not install it outdoors. If installed outdoors, the aging of parts
causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of
electric shock.

• Use the unit only with the voltage specied on the unit. Using a voltage higher than that which is specied
may result in re or 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 re or electric shock.

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

· 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 it is malfunctioning (no tone sounds.)

• To prevent a re or electric shock, never open nor remove the unit case as there are high voltage components
inside the unit.

• 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 re or electric shock.

• Do not insert nor drop metallic objects or ammable materials in the ventilation slots of the VX-3000F’s cover,
as this may result in re or electric shock.

• When replacing the fuse, be sure to use the supplied one. Using any other fuse than supplied may cause re
or electric shock.

CAUTION

When Installing the Unit

• Do not block the ventilation slots in the VX-3000F’s cover. Doing so may cause heat to build up inside the unit
and result in re. Also, periodically clean the ventilation slots of dust.

• 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 re or electric
shock.

• Note correct polarity (positive and negative orientation) when connecting the power supply cord. Reversed
polarity connections will cause damage to the unit.

When the Unit is in Use

• Do not operate the unit for an extended period of time with the sound distorting. Doing so may cause the
connected speakers to heat, resulting in a re.

• Contact your TOA dealer as to the cleaning. If dust is allowed to accumulate in the unit over a long period of
time, a re or damage to the unit may result.

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