If the equipment is to be installed in an area serviced by an IT power line

network, as is found in many areas of Norway, special attention should be

given that the installation is in accordance with IEC 60728-11, in particular

Annex B and Figure B.4.

• In areas of high surge events or poor grounding situations and areas prone

to lightning strikes, additional surge protection may be required (i.e.

PF11VNT3 from American Power Conversion) on the AC, RF, and Ethernet

lines.

• When the Wideband Cable Modem is connected to a local computer through

USB or Ethernet cables, the computer must be properly grounded to the

building/residence AC ground network. All plug-in cards within the computer

must be properly installed and grounded to the computer frame per the

manufacturer’s specifications.

• Do not use spray cleaners or aerosols on the Wideband Cable Modem.
• Clean the Wideband Cable Modem only with a dry cloth.
