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

WARNING

Indicates a potentially

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

• Install the bracket only in a location that can structurally

support the weight of the bracket and the speaker as
well. Doing otherwise may cause the speaker to fall off,
resulting in 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.

CAUTION 

Indicates a potentially hazardous

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

• 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.
