Make sure to check your country's restrictions and law regarding the use of lasers
INSTALLATION OF THE UNIT
The units from 3B class and 4 class, exclusively used in open air, should be installed by
experienced and qualified professionals, trained to the specific risks of lasers and should handle a
user manual.
The area reserved for the public should be limited up to 3 meters above the ground and to 2.5
meters from the public. This zone should be indicated and marked on the ground. In this area, it is
not possible to make "pencil beams" (through the output being a narrow beam which is diffraction-
limited) in the direction of people, whatever the laser class is, except if a determined area has been
defined of 4 meters radius from the public and visibly marked on the ground.
Only laser beams of wavelengths divergence concentrated their power at a large distance are
authorized.
OPERATION OF THE UNIT
The use of lasers is out of the reach of people when considering:
-
That the unit is situated at 3 meters above the floor at least
-
That a safety area is defined within 5 meters radius
-
The user takes the responsibility that the units under 3B class or 4 class are mounted by a
-
qualified technician and experienced to the risks of lasers. This technician must stay around
during all the time the lasers work and he must be able to stop the units in case some
technical problems would occur. While the installation is on, the technician should wear
protective glasses.
Please remind the following remarks:
-
Laser light is different from any other light source with which you may be familiar. The light
-
from this product can potentially cause eye injury if not set up and used properly.
Laser light is thousands of times more concentrated than light from any other kind of light
-
source. This concentration can cause instant eye injuries, by burning the retina. Even if you
can not feel heat from a laser beam, it can still injure or blind you or the audience.
Never look at the laser aperture or laser beams.
-
Do not direct the laser beam to people.
-
Do not leave the device running without the presence of qualified professionals.
-
EXPELEC can not liable for damages caused by incorrect installations and unskilled operation.
