1.4. Regulation declaration
The changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment. To comply with the FCC RF exposure compliance requirements, this device and its
antenna must not be co-located or operating to conjunction with any other antenna or transmitter.
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 instruction, may cause harmful interference to radio communication. However, there is no
grantee that interference will not occur in a particular installation. If this equipment dose 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.
This device should have at least 20 cm separation distance to persons.
