Safety precautions

Information regarding use of loudspeakers

WARNING!

Never stand in the immediate vicinity of loudspeakers driven at a high
level. Professional loudspeaker systems are capable of causing a sound
pressure level detrimental to human health. Seemingly non-critical
sound levels (from approx. 95 dB SPL) can cause hearing damage if
people are exposed to it over a long period.

In order to prevent accidents when deploying loudspeakers on the
ground or when flown, please take note of the following:

When setting up the loudspeakers or loudspeaker stands, make sure
they are standing on a firm surface. If you place several systems on top
of one another, use straps to secure them against movement.

Only use accessories which have been tested and approved by d&b for
assembly and mobile deployment. Pay attention to the correct
application and maximum load capacity of the accessories as detailed in
our specific "Mounting instructions" or in our "Flying system and rigging
manuals".

Ensure that all additional hardware, fixings and fasteners used for
installation or mobile deployment are of an appropriate size and load
safety factor. Pay attention to the manufacturers' instructions and to the
relevant safety guidelines.

Regularly check the loudspeaker housings and accessories for visible
signs of wear and tear and replace them when necessary.

Regularly check all load bearing bolts in the mounting devices.

CAUTION!

Loudspeakers produce a static magnetic field even if they are not
connected or are not in use. Therefore make sure when erecting and
transporting loudspeakers that they are nowhere near equipment and
objects which may be impaired or damaged by an external magnetic
field. Generally speaking, a distance of 0.5 m (1.5 ft) from magnetic
data carriers (floppy disks, audio and video tapes, bank cards, etc.) is
sufficient; a distance of more than 1 m (3 ft) may be necessary with
computer and video monitors.
