Radio frequency Interference Requirements
The operation of this device in the 5.15 GHz to 5.25 GHz frequency range is
restricted to indoor use. FCC regulations require this product to be used indoors
while operating at 5.15 GHz to 5.25 GHz to reduce the potential for harmful
interference. However, the operation of this device in the 5.25 GHz to 5.35 GHz
frequency range is allowed for both indoor and outdoor use. High power radars
are allocated as primary users of the 5.25 GHz to 5.35 GHz and 5.65 GHz to 5.85
GHz bands. These radar stations can cause interference with and/or damage to
this device.
FCC Warning
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed 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. No guarantee exists that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception (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 radio/TV receiving antenna.
• Increase the separation between the equipment and the radio/TV receiver.
• Connect the equipment into an outlet on a circuit different from that to
which the radio/TV receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Modifications made to the product, unless expressly approved by SilverNet
Limited, could void the user’s authority to operate the equipment.
RF Exposure Requirements
To ensure compliance with FCC RF exposure requirements, the antenna used for
this device must be installed to provide a separation distance of at least 20 cm
from all persons and must not be co-located or operating in conjunction with any
other antenna or radio transmitter. Installers and end-users must follow the
installation instructions provided in this user guide.
