5.1 Positioning the LRAD for Operation
Many factors must be considered when positioning the LRAD
1950XL for hailing and warning
operations. The LRAD
1950XL Operations Zones shown in Figure 1 must always be taken into
account to ensure that personnel are not exposed to excessive sound pressure levels.
Factors to consider when placing the LRAD
1950XL include, but are not limited to, the
following:
•
All long-range communication devices should have an unobstructed transmission path to the
anticipated areas in which it will be aimed. Even small mast antennas may reflect some
sound energy decreasing the effectiveness of the unit as well as increasing reflected noise
levels for the operator and others nearby.
•
Placement should be chosen so as to minimize or avoid transmission over decks or balconies
where personnel may be located.
•
Shipboard operations should place the LRAD
1950XL
as close to the ship’s sides, bow, or
stern as possible.
