Caution: The user is cautioned that changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
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.
This equipment complies with FCC’s RF radiation exposure limits set forth for an uncontrolled environment. The antenna(s)
used for this transmitter must be installed and operated to provide a separation distance of at least 20 cm from all persons
and must not be collocated or operating in conjunction with any other antenna or transmitter. Installers must ensure that
20cm separation distance will be maintained between the device (excluding its handset) and users.
