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 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 Modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. FCC Compliance Information : 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 IMPORTANT NOTE: FCC RF Radiation Exposure Statement: This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body.This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna, 3) OEM shall not supply any tool or info to the end-user regarding to Regulatory Domain change. As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. Maximum antenna gain allowed for use with this device is 1. 2 dBi End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: “Contains FCC ID: SNL-36204210” Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual. GUIDANCE REQUIREMENT / RESPONSIBILITY: Pursuant to the Transmitter Module Equipment Authorization Guide (KDB 996369 D01), the party responsible for the module grant shall provide guidance to the host manufacturer for compliance with the Part 15B requirements.

FCC ID: SNL-36204210 ATTACHMENT ** MPE Calculations ** The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G EIRP = 18.53 dBm + 1.2 dBi EIRP = 19.73 dBm Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) Power density at the specific separation: S = PG/(4R 2 π) Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) S = (71.29 *1.32) / (4 * 20 2 * π) S = 0.0187 mW/cm 2 The Maximum permissible exposure (MPE) for the general population is 1 mW/cm 2 . The power density does not exceed the 1 mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules. Estimated safe separation: R = √(PG / 4π) Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) R = √(71.29 *1.32/ 4π) R = 2.74 Cm The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log -1 (1.2 / 10) G = 1.32
