Danger
Please observe that with a switched-on laser the laser
pointer will go on as soon as you press the
measurement button (6) or activate continuous
measurement.
Warning of laser radiation
Class 2 laser radiation.
Lasers of class 2 only radiate in the visible range and
during continuous wave operation (lasting beam) no
more than 1 milliwatt (mW) of output will be emitted.
Looking directly into the laser beam for a longer period
of time (more than 0.25 seconds) can cause damage to
the retina.
Avoid looking directly into the laser beam. Never look
into the laser beam using optical aides. Do not
suppress the winking reflex when looking into the laser
beam unintentionally. Never point the laser beam at
people or animals.
