Laser Classification
The CEM produced a visible laser beam which emerges from the front of the instrument.
Do not stare into the laser beam or direct it towards other people unnecessarily. Eye protection is normally afforded
by aversion responses including the blink reflex.
Looking directly into the beam with optical aids
(e.g. binoculars, telescopes) can be hazardous.
Do not look directly into the beam with optical aids.
Looking into the laser beam may be hazardous to the eyes.
Do not look into the laser beam. Make sure the laser is aimed above or below eye level.

.4 Measuring
Press again to trigger the distance measurement. The measured value is displayed immediately.
The continuous measurement function (tracking) is used for the
transferring of measurements, e.g., from construction plans. In
continuous measurement mode, the measuring tool can be moved
to the target, whereby the measured value is updated approx. every
0.5 seconds in the third line. The corresponding minimum and
maximum values are displayed in the first and second
line. As an example, the user can move from a wall to the required
distance, while the actual distance can be read continuously. For
continuous measurement, push button until the indicator for
continuous measurement appears in the display. And press MEAS
or Clear button again to stop the function. The function is terminated
automatically after continuous 100 times measurement.
Press to activate the laser.
