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.

When Installing the Unit

• Install the unit only in a location that can structurally
support the weight of the unit and the mounting bracket.
Doing otherwise may result in the speaker falling down
and causing personal injury and/or property damage.

When the Unit is in Use

• Should the following irregularity be found during use,
immediately stop operating the unit 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 it is malfunctioning (no tone sounds.)

When Installing the Unit

• When unpacking or moving a heavy speaker, be sure to
handle the unit with two or more persons. Falling or
dropping the speaker may cause personal injury and/or
property damage.

• Since installation requires specialized skills and
professional experience, always consult the shop from
where the unit was purchased before beginning
installation. If the speaker should fall, it could result in
electrical shocks or other personal injuries.

When the Unit is in Use

• Do not operate the speaker 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.

• Use only the specified matching transformer. If any other
matching transformer is used, it could cause damage to
the connected speaker, matching transformer itself, and
amplifier.

• Have the speaker unit checked periodically by the shop
from where it was purchased. Failure to do so may result
in corrosion or damage to the speaker or its mounting
bracket that could cause the speaker to fall, possibly
causing personal injury.

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