FCC ID: EMJM7B301 Report No.: RF950712A05A Reference No.: 950712A11 Operational Description The device is a Frequency Hopping device with 79 hopping frequencies. The antenna type is Printed Antenna and there is no antenna connector used. The EUT is a unit that contains a Bluetooth radio module. Bluetooth is a short-range wireless technology operating in the 2.4GHz band. It enables devices to have the ability to form networks and exchange information. The other instruction, please have a look at the user’s manual.

Report No: SA950712A05A1 Reference No.: 950712A11 RF EXPOSURE REPORT REPORT NO.: SA950712A05A MODEL NO.: RF-BTMSE ACCORDING: FCC Guidelines for Human Exposure IEEE C95.1 APPLICANT : PRIMAX ELECTRONICS LTD. ADDRESS : No. 669, Ruey Kuang Road, Neihu, Taipei, Taiwan, R.O.C. ISSUED BY : Advance Data Technology Corporation LAB ADDRESS : No. 47, 14 th Ling, Chia Pau Tsuen, Linko Hsiang 244, Taipei Hsien, Taiwan, R.O.C. Report No: SA950712A05A2 Reference No.: 950712A11 RF Exposure Measurement 1. Introduction In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC) calibrated for antenna measurement in ADT, and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 300-1500......F/15006 1500-100,000......1.030 F = Frequency in MHz Report No: SA950712A05A3 Reference No.: 950712A11 3. Friis Formula Friis transmission formula: Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance 20cm.

EUT Operating condition The software provided by manufacturer enabled the EUT to transmit data at lowest, middle and highest channel individually. Report No: SA950712A05A4 Reference No.: 950712A11 5. Conclusion No Evaluation Required if power is below this threshold: F(GHz)mW Low2.402 High2.480 24.58 Maximum measured transmitter power: Pout (dBm)Pout (mW) Conducted Power0.691.172 EIRP Power0.691.172 *Note: The antenna is Printed antenna with 0dBi gain Threshold for no SAR evaluation is 24.58mW Transmitter power is 1.172mW Conclusion: No SAR evaluation required since Transmitter Pout is below FCC threshold
