FCC WARNING
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two
conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference
that may cause
undesired operation.
Any 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.
Specific absorption rate (SAR):
This Clip meets the government’s requirements for exposure to radiowaves. The
guidelines are based on standards developed by independent scientific
organizations through periodic and thorough evaluation of scientific studies.
The standards include a margin of safety designed to ensure the safety of all
people regardless of their age or health.
The FCC Statement of Exposure to RF and the SAR limit for the United States
(FCC) is 1.6 W/kg average for each gram of tissue. This device was tested for
typical operations of use on the body, with the back of the Clip at 0mm from
the body. To maintain compliance with FCC RF exposure requirements, use
accessories that maintain a distance of 0mm between the user’s body and the
back of the Clip. Functioning in the body This device was tested for typical
operations of use in the body. To comply with RF exposure requirements, a
minimum separation distance of 0mm must be maintained between the user’s body
and the telephone, including the antenna. Use only the supplied antenna or an
approved antenna.
The maximum results of Specific Absorption Rate (SAR) found during testing for
Modj0005 are 0.587W/kg
