Section 3 Installation
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 modem 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 this recommendation not will be followed it can jeopardise the warranty.
Maintenance
No maintenance is required, as long as the unit is used as intended within the
specified conditions.

of forced nitrogen and some kind of cleaning stick.
