Specific Absorption Rate (SAR) certification information
Your device conforms to U.S. Federal Communications Commission (FCC) standards that limit human exposure to radio frequency (RF) energy emitted by radio and telecommunications equipment. These standards prevent the sale of mobile devices that exceed a maximum exposure level (known as the Specific Absorption Rate, or SAR) of 1.6W/kg.
SAR information on this and other model devices can be accessed online on the FCC’s website throughtransition.fcc.gov/oet/rfsafety/sar.html.
In normal use, the actual SAR is likely to be much lower, as the device has been designed to emit only the RF energy necessary to transmit a signal to the nearest base station. By automatically emitting lower levels, when possible, your device reduces your overall exposure to RF energy.
The FCC has granted an Equipment Authorization for this model device based on the compliance of all reported SAR levels with the FCC RF exposure guidelines. This device has an FCC ID number: 2AZP5-L1EBAL [ Model Number: L1 ] and the specific SAR levels for this device can be found at the following FCC website: www.fcc.gov/oet/ea/.

FCC Warning

Labeling requirements.
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.
Information to the user.
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Information to the user.
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 rovide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed nd 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 articular 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  s 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.

Absorption Rate (SAR) information:
This device meets the government’s requirements for exposure to radio waves. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluations of scientific studies. The standards include a substantial safety margin designed to assure the safety of all people regardless of age or health.
FCC RF Exposure Information and Statement The SAR limit of the USA (FCC) is 1.6 W/kg averaging over one gram of tissue. This device was tested for typical body-worn operations with the head 0mm and 0mm from the body. Maintain compliance with FCC RF exposure requirements, and use accessories that maintain an appropriate separation distance between the user’s body and the back of the device. The use of belt clips, holsters, and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements does not comply with FCC RF exposure requirements and should be avoided. Use only the supplied or approved antenna.
