Toa ES-0422, ES-0424, ES-0426 Instruction Manual

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.

• 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.

• 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.)

• 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.

• 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.

Please follow the instructions in this manual to obtain the optimum results from this unit.
We also recommend that you keep this manual handy for future reference.
