FCC Regulations
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  . 
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 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 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 10 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 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 devices employs a unit of 
measurement known as the Specific Absorption Rate, or SAR . The 
SAR limit set by the FCC is 1 .6 W/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 .
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: SRQ-K88 .
For this device, the highest reported SAR value for usage near the 
body is 1.19 W/kg .
