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.
WARNING
hazardous situation which, if mishandled, could result in
death or serious personal injury.
• Use only the specified amplifier output voltage and
impedance, as exceeding the specified limits could result
in fire or other failures (high-impedance applications).
• To avoid accidental air explosions, do not use the unit
around gasoline, thinner or other combustibles.
• 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 unit 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 unit and the unit
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.
• Attach the safety wire to the unit when mounting in
locations high above the ground. Failure to do so could
result in personal injury if the speaker should later fall for
any reason.

WARNING
hazardous situation which, if mishandled, could result in
death or serious personal injury.
• Avoid mounting the unit 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.
CAUTION
Indicates a potentially hazardous
situation which, if mishandled, could result in moderate
or minor personal injury, and/or property damage.
• To avoid electric shocks, be sure to switch off the
amplifier power when connecting the speaker.
• Avoid installing the unit in humid or dusty locations, or in
locations exposed to heaters, solvents, acid, alkali,
smoke, or steam, as excessive exposure to these factors
could result in the speaker falling off, electric shock or
fire.
• Do not operate the unit 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.
• Do not stand or sit on, nor hang down from the unit as
this may cause it to fall down or drop, resulting in
personal injury and/or property damage.
• Have the unit periodically checked by the shop from
where it was purchased. Failure to do so could result in
the speaker falling off due to damage or corrosion to the
speaker or its mounts, and possible personal injury.
