Fibre optic equipment needs special treatment. It is very sensitive to dust and dirt.
If the fibre will be disconnected from the unit the protective hood on the transmit-
ter/receiver must be connected. The protective hood must be kept on during trans-

If these recommendations are not followed the warranty might be jeopardized.
