RF Exposure / MPE Calculation No. : 12622648S-B, 12622648S-C, 12622648S-D Applicant : JVC KENWOOD Corporation Type of Equipment : GPS NAVIGATION SYSTEM Model No. : DNX996XR FCC ID : IOMJ5220 JVC KENWOOD Corporation declares that Model: DNX996XR complies with FCC radiation exposure requirement specified in the FCC Rule 2.1091 (for mobile). RF Exposure Calculations: The following information provides the minimum separation distance for the highest gain antenna provided with the “DNX996XR“ 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. Bluetooth part: This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain, and considering a 1mW/cm^2 uncontrolled exposure limit. The Friis formula used was: PG S  Where 4  r2 P= 1.00 mW (Maximum average output power) Time average was used for the above value in consideration of 6-minutes time-averaging Burst power average was used for the above value in consideration of worst condition. G= 0.589 Numerical Antenna gain; equal to -2.3 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.00012 mW/cm WLAN (2.4 GHz) part: This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain, and considering a 1mW/cm^2 uncontrolled exposure limit. The Friis formula used was: PG S  4   r2 Where P= 36.73 mW (Maximum average output power) Time average was used for the above value in consideration of 6-minutes time-ave Burst power average was used for the above value in consideration of worst condit G= 0.363 Numerical Antenna gain; equal to -4.4dBi r= 20 cm (Separation distance) Power Density Result S = 0.00265 mW/cm2

WLAN (5 GHz) part: This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain, and considering a 1mW/cm^2 uncontrolled exposure limit. The Friis formula used was: PG S  Where 4  r2 P= 20.13 mW (Maximum average output power) Time average was used for the above value in consideration of 6-minutes time-averaging Burst power average was used for the above value in consideration of worst condition. G= 0.525 Numerical Antenna gain; equal to -2.8 dBi r= 20 cm (Separation distance) 2 Power Density Result S = 0.00210 mW/cm Therefore, if Bluetooth and WLAN 2.4 GHz transmit simultaneously, S=0.00012 mW/cm2 + 0.00265 mW/cm2 =0.00277 mW/cm2 Even taking into account the tolerance, this device can be satisfied with the limits. Therefore, if Bluetooth and WLAN 5 GHz transmit simultaneously, S=0.00012 mW/cm2 + 0.00210 mW/cm2 =0.00222 mW/cm2 Even taking into account the tolerance, this device can be satisfied with the limits.
