T his device complies with Part 15 of the FCC Rules. Operation is s ubject to the following two conditions: (1) this device may not cause h armful interference, and (2) this device must accept any interference r eceived, including interference that may cause undesired operation. NOTE:This equipment has been tested and found to comply with the limits for a Class B d igital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provid e r easonable protection against harmful interference in a residential installation. This e quipment generates, uses and can radiate radio frequency energy and, if not installed a nd used in accordance with the instructions, may cause harmful interference to radio c ommunications. Howerver, there is no guarantee that interference will not occur in a p articular installation. If this equipment does cause harmful interference to radio or t elevision reception. w hich can be determined by turning the equipment off and on, the user is encouraged to t ry 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 form that to which the r eceiver is connected. - -consult the dealer or an experienced radio/TV technician for help. C AUTION: T o comply with FCC RF exposure compliance requirements, a separation distance of at l east 20 cm must be maintained between the antenna of this device and all persons. Thi s t ransmitter must not be co-located or operating in conjunction with any other antenna or t ransmitter.

Safety Human exposure 6.1 Radio Frequency Exposure Compliance 6.1.1 Maximum Permissible Exposure RESULT: Passed Test standard : RSS-102 Issue 4 FCC KDB Publication 447498 FCC 1.1310 MPE Calculation According to the formula π 2 4 * R GPout Pd= Where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = Antenna gain in numeric π = 3.14159 R = Distance between observation point and the center of radiator in cm The antenna of this product, under normal use condition, is at least 20cm away from the body of the user. Warning statement to the user for keeping the safety distance from the antenna should be included in the user manual. The highest measured power is 9.55 dBm at 2476 MHz for wireless operation, hence the Maximum Permissible Exposure (MPE) value: 2 22 /005671.0 14159.3*20*4 16.3*02.9 4 * cmmW R GPout Pd=== π < 1mW/cm 2 The summed maximum permissible exposure (MPE) level is 0.005671mW/cm 2 . It is less than MPE limit 1mW/cm 2 , therefore the device is exclusion from SAR test, and compliance with MPE limit.
