RF Exposure / MPE Calculation No. : 10273917H Applicant : Yamaha Corporation Type of Equipment : Wireless Module Model No. : BTCARD4 FCC ID : A6RBTCARD4A Yamaha Corporation declares that Model : BTCARD4 ⇒ complies with FCC radiation exposure requirement specified in the FCC Rules 2.1091 (for mobile). RF Exposure Calculations: ← The following information provides the minimum separation distance for the highest gain antenna provided with the “BTCARD4“ as calculated from (B) Limits for General Population / Uncontrolled Exposure of TABLE 1- LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) of §1.1310 Radiofrequency radiation exposure limits. This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain, and considering a 1.0mW/cm^2 uncontrolled exposure limit. The Friis formula used was: S = (P * G) / (4* π * r2) Where P= 0.94 mW (Maximum average output power) G= 1.58 Numerical Antenna gain; equal to 2.00 dBi r= 20.0 cm For: BTCARD4 S= 0.00030 mW/cm2
