Chapter 1: Safety requirements
■
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, Ethernet and Phone lines.
■
When the Telephony Gateway is connected to a local computer through 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.
■
Ensure proper ventilation. Position the Telephony Gateway so that air flows freely
around it and the ventilation holes on the unit are not blocked.
■
Do not mount the Telephony Gateway on surfaces that are sensitive to heat and/or
which may be damaged by the heat generated by the modem, its power supply, or other
accessories.
FCC Part 15
This equipment has been tested and found to comply with the requirements for a Class B
digital device under Part 15 of the Federal Communications Commission (FCC) rules. These
requirements are intended to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the following
measures:
■
Reorient or relocate the receiving antenna.
■
Increase the separation between the equipment and receiver.
■
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
■
Consult the dealer or an experienced radio/TV technician for help.
CAUTION:
FCC Caution.
Changes or modifications to this equipment not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
RF Exposure
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance of
10.2 inches (26 cm) between the radiator and your body. This transmitter must not be co-
located or operating in conjunction with any other antenna or transmitter.
