Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning! Do not open connected unit. Hazardous voltage may occur within this
unit when connected to power supply.
Class 1 Laser Product
Do not look directly into fibre optical fibre port or any connected fibre although
this unit is designed to meet the Class 1 Laser regulations.

Note. 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.
Cleaning of the optical connectors
In the event of contamination, the optical connectors should be cleaned by the use of
forced nitrogen and some kind of cleaning stick.
Recommended cleaning fluids:
• Methyl-, ethyl-, isopropyl- or isobutyl-alcohol
• Hexane
• Naphtha
Maintenance
No maintenance is required, as long as the unit is used as intended within the specified
conditions.
