When using a fiber optic port, never look at the transmit laser while
it is powered on. Also, never look directly at the fiber TX port and
fiber cable ends when they are powered on.
Ne regardez jamais le laser tant qu'il est sous tension. Ne regar-
dez jamais directement le port TX (Transmission) à fibres optiques
et les embouts de câbles à fibres optiques tant qu'ils sont sous
tension.
Niemals ein Übertragungslaser betrachten, während dieses einge-
schaltet ist. Niemals direkt auf den Faser-TX-Anschluß und auf die
Faserkabelenden schauen, während diese eingeschaltet sind.
Installation and removal of the unit must be carried out by qualified personnel only.
