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 radiated 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.

-Consult the dealer or an experienced radio/TV technician for help.
Caution: Changes or modifications not expressly approved by the party responsible for compliance could
void the user‘s authority to operate the equipment.
FCC RF Exposure Information (SAR)
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 United States.
During SAR testing, this device is set to transmit at its highest certified power level in all tested frequency
bands, and placed in positions that simulate RF exposure near the body with the separation of 10 mm.
Although the SAR is determined at the highest certified power level, the actual SAR level of the 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 power required to reach the network. In general, the closer
you are to a wireless base station antenna, the lower the power output.
The exposure standard for wireless employs a unit of measurement known as the Specific Absorption
Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg.
ZTE MF90 Getting Started
Confidential and Proprietary Information of ZTE CORPORATION 15
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 www.fcc.gov/oet/ea/fccid
after searching on FCC ID: SRQMF90.
For this device, the highest reported SAR value for near the body is 1.36 W/kg.
While there may be differences between the SAR levels of various devices and at various positions, they
all meet the government requirement.
SAR compliance for body operation is based on a separation distance of 10 mm between the unit and the
human body. Carry this device, at least 10 mm away from your body to ensure RF exposure level
compliant or lower to the reported level. To support body operation, choose the belt clips or
holsters, which do not contain metallic components, to maintain a separation of 10 mm between this and
your body.
