For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.

Optical Safety Instructions
Laser!
This symbol inform of the risk of exposure to laser beam and light emitting devices (LEDs)
from an electrical device. Eye protection per manufacturer notice shall review before
servicing.
When a connector is removed during installation, testing, or servicing, or when an energized fiber is broken, a risk of
ocular exposure to optical energy that may be potentially hazardous occurs, depending on the laser output power.
The primary hazards of exposure to laser radiation from an optical-fiber communication system are:
Damage to the eye by accidental exposure to a beam emitted by a laser source
Damage to the eye from viewing a connector attached to a broken fiber or an energized fiber
