Fibre Optic Handling
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
transmitter/receiver must be connected. The protective hood must be kept on during
transportation. The fibre optic cable must also be handle the same way.
If these recommendations are not followed the warranty might be jeopardized.
Maintenance
No maintenance is required, as long as the unit is used as intended within the
specified conditions.
Cleaning of the Optical Connectors
In the event of contamination, the optical connectors should only be cleaned by the
use of recommended cleaning fluids and correct cleaning equipment.
