Safety and Precautions for Lasers
The optical transmitter used in the ION-B contains a laser which has a power level that is not
dangerous for health. However it is classifi ed as class 1 equipment (in accordance with EN60825).
It is nevertheless prudent, during the installation phase, to observe the following rules:
• Never look directly inside the optic connector exit of the transmitter when it is switched on.
The wavelength of the laser is not visible to the human eye, which means that long-term
damage will not be immediately known.
• When working with the optical connectors, check at each end that both transmitting lasers
are switched off.
