- Consult the dealer or an experienced radio/TV technician for help.
Laser classification
Diagram Description: An image shows the PREXISO device with a laser beam exiting, labeled "Laser exit".
The device produces visible laser beams, which are emitted from the instrument. It is a Class 2 laser product in accordance with: IEC60825-1 : 2007 "Radiation safety of laser products".
Laser Class 2 products:
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.
⚠️ WARNING: Looking directly into the beam with optical aids (e.g., binoculars, telescopes) can be hazardous.
❗ CAUTION: Looking into the laser beam may be hazardous to the eyes.
Diagram Description: A graphic displays "Laser Radiation" information, including "Do not stare into the beam", "Laser class 2", "acc. IEC 60825-1:2007", "Maximum radiant power: <1mW", "Emitted wavelength: 620-690nm", "Beam divergence: 0.16 x 0.6 mrad", "Impulse duration: 0.2 x 10⁻⁹s - 0.8 x 10⁻⁹s".
