FCC Regulations
This mobile phone complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference.
(2) this device must accept any interference received, including interference
that may cause undesired operation.
This mobile phone has been tested and found to comply with the limits for a Class B digital device, under 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 by 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 the receiver.
- Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/IV technician for help.
FCC Note
Caution: Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
RF Exposure Information (SAR)
This phone 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 was set to transmit at its highest certified power level in all tested frequency bands, and placed in positions that simulate RF exposure in usage against the head with no separation, and near the body with the separation of 15 mm. 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 phone is designed to operate at multiple power levels 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 devices employing a unit of measurement is known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg.
This device complies with SAR for general population /uncontrolled exposure limits in ANSI/EEE C95.1-1992 and has been tested by the measurement methods and procedures specified in all 1528. The FCC has granted Equipment Authorization for this model phone with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. SAR information on this model, phone 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: 2AUYFRMX. ooo For this device, the highest reported SAR value for usage against the head is XXX W/kg, and for usage near the body is XXX W/kg.While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirements.
SAR compliance for body-worn operation is based on a separation distance of XX
mm between the unit and the human body. Carry this device at least XX mm away
from your body to ensure the RF exposure level is compliant or lower than the
reported level. To support body-worn operation, choose the belt clips or
holsters, which do not contain metallic components, to maintain a separation
of XX mm between this device and your body. RF exposure compliance with any
body-worn accessory, that contains metal, was not
tested and certified, and the use of such body-worn accessories should be
avoided. Regulatory Steps to search E-label: Go to Settings -About device –
