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. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.

FCC ID : 2A5PJ-LM138G  Test Standards and Limits 1. According to KDB 447498 D01 v06, Section 4.3.1 2. FCC Radiofrequency radiation exposure limits: The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤50 mm are determined by: [(max power of channel)/(min test separation distance)]*[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where • f(GHz) is the RF channel transmit frequency in GHz • Power and distance are rounded to the nearest mW and mm • The result is rounded to one decimal place for comparison • 3.0 and 7.5 are referred to as the numeric thresholds The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm, and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 4.1 f) is applied to determine SAR test exclusion. For 2.4G band device, the limit of worse case is P max ≤3.0*D min )/ f =3.0*5/ [√2.474] =9.537mW  Measurement and Calculation 1. Maximum transmit power 2.4G SRD, Antenna Gain: -5.37dBi Operation Mode Channel Number Channel Frequency (MHz) EIRP (dBm) 2.4G SRD 1 2408 4.82 3 2440 2.47 16 2474 1.37 * EIRP[dBm] = E[dBμV/m] + 20 log(d[meters]) - 104.77 2. MPE Calculation According to the formula. calculate the EIRP test result: EIRP= 3.03mW < 9.525mW So the SAR report is not required. -End of the Report-
