INSTRUCTION MANUAL
BOX SPEAKER BS-4W
Thank you for purchasing TOA’s Box Speaker.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read
all the instructions in this section for correct and
safe operation.
• Be sure to follow all the precautionary instructions
in this section, which contain important warnings
and/or cautions regarding safety.
• After reading, keep this manual handy for future
reference.
• Refer all installation work to the dealer from whom
the speaker was purchased. Installation requires
extensive technical knowledge and experience.
The speaker may fall off if incorrectly installed,
resulting in possible personal injury.
• Install the speaker only in a location that can
structurally support the weight (1.5 kg or 3.31 lb)
of the speaker and the mounting bracket. Doing
otherwise may result in the speaker falling down and
causing personal injury and/or property damage.
• Do not use other methods than specified to mount
the bracket. Extreme force is applied to the speaker
and the speaker could fall off, possibly resulting in
personal injuries.
• Use nuts and bolts that are appropriate for the
ceiling’s or wall’s structure and composition. Failure
to do so may cause the speaker to fall, resulting in
material damage and possible personal injury.
• Tighten each nut and bolt securely. Ensure that
the bracket has no loose joints after installation
to prevent accidents that could result in personal
injury.
• Do not mount the speaker in locations exposed
to constant vibration. The mounting bracket can
be damaged by excessive vibration, potentially
causing the speaker to fall, which could result in
personal injury.
• Should the following irregularity be found during
use, immediately stop using the speaker, and
contact your nearest TOA dealer. Make no further
attempt to operate the speaker in this condition as
this may cause fire or electric shock.
· If you detect smoke or a strange smell coming
from the speaker.
· If water or any metallic object gets into the speaker
· If the speaker falls, or the speaker case breaks
· If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor
remove the speaker case. Refer all servicing to
qualified service personnel.
• Avoid touching the speaker’s sharp metal edge to
prevent injury.
• Do not place heavy objects on the speaker as this
may cause it to fall or break which may result in
personal injury and/or property damage. In addition,
the object itself may fall off and cause injury and/or
damage.
• Do not operate the speaker for an extended period
of time with the sound distorting. Doing so may
cause the connected speakers to heat, resulting in
a fire.
• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property damage.
• Have the speaker 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.
