6 Confidential and Proprietary Information of ZTE CORPORATION
FCC Compliance
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.
•
This device 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.
Changes or modifications not expressly approved by the party responsible for compliance could void
the user‘s authority to operate the equipment.
•
The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter.
Radio Frequency (RF) Energy
This model device meets the government’s requirements for exposure to radio waves.
This device is designed and manufactured not to exceed the emission limits for exposure to radio
frequency (RF) energy set by the Federal Communications Commission of the U.S. Government:
The exposure standard for wireless devices employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. *Tests for SAR are conducted using
standard operating positions accepted by the FCC with the device transmitting at its highest certified
power level in all tested frequency bands. Although the SAR is determined at the highest certified power
level, the actual SAR level of the device while operating can be well below the maximum value. This is
because the device is designed to operate at multiple power levels so as to use only the poser required to
reach the network. In general, the closer you are to a wireless base station antenna, the lower the power
output.
The highest SAR value for the model device as reported to the FCC when worn on the body, as described
in this user guide, is 0.908W/kg(Body-worn measurements differ among device models, depending upon
available enhancements and FCC requirements.)
While there may be differences between the SAR levels of various devices and at various positions, they
all meet the government requirement.
The FCC has granted an Equipment Authorization for this model device with all reported SAR levels
evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model device
is on file with the FCC and can be found under the Display Grant section of http://www.fcc.gov/oet/fccid
after searching on FCC ID: Q78-MF665C
For body worn operation, this modem has been tested and meets the FCC RF exposure guidelines for use
with an accessory that contains no metal and the positions the handset a minimum of 0.5 cm from the
body. Use of other enhancements may not ensure compliance with FCC RF exposure guidelines.
