Do not use the laser goggles (accessory) as
u
sunglasses or while driving. The laser goggles do not
provide full UV protection and impair your ability to see
colours.
Have the measuring tool serviced only by a qualified
u
specialist using only original replacement parts. This
will ensure that the safety of the measuring tool is main-
tained.
Do not let children use the laser measuring tool unsu-
u
pervised. They could unintentionally blind themselves or
other persons.
Do not use the measuring tool in explosive atmo-
u
spheres which contain flammable liquids, gases or
dust. Sparks may be produced inside the measuring tool,
which can ignite dust or fumes.
Do not use any optical instruments such as binoculars
u
or magnifying glasses to view the radiation source.
Doing so can damage your eyes.
Keep the measuring tool and the magnetic
accessories away from implants and other
medical devices, e.g. pacemakers or insulin
pumps. The magnets inside the measuring tool
and accessories generate a field that can impair
the function of implants and medical devices.
Keep the measuring tool and the magnetic accessor-
u
ies away from magnetic data storage media and mag-
netically sensitive devices. The effect of the magnets in-
side the measuring tool and accessories can lead to irre-
versible data loss.
