SPECIFICATIONS/MANUAL
FCC15.19
This device is verified to comply with part 15 of the FCC Rules for use
with cable television service.
FCC 15.105
Note: 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. 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.
FCC 15.21
The users manual or instruction manual for an intentional or unintentional
radiator shall caution the user that changes or modifications not expressly
approved by the party responsible for compliance could void the user's
authority to operate the equipment. In cases where the manual is provided
only in a form other than paper, such as on a computer disk or over the
Internet, the information required by this section may be included in the
manual in that alternative form, provided the user can reasonably be
expected to have the capability to access information in that form.
