FCC ID: VEB-NKRDCMA82 5.6 Maximum permissible exposure (MPE) For test instruments and accessories used see section 6 Part CPC 3. 5.6.1 Description of the test location Test location: AREA 4 5.6.2 Photo documentation of the test set-up 5.6.3 Applicable standard According to FCC Part 15, Section 15.407(f): U-NII devices are subject to the radio frequency radiation exposure requirements specified in Section 1.1307(b), 2.1091 and 2.1093 of this chapter, as appropriate. All equipment shall considered to operate in a “general population/uncontrolled” environment. The test methods used comply with ANSI/IEEE C95.1-2005, “IEEE Standard for Safety Levels with respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz”. mikes-testingpartners gmbh File No. T34715-00-03AA, page 29 of 47 Ohmstrasse 2-4  94342 STRASSKIRCHEN  GERMANY Tel.:+49(0)9424-94810  Fax:+49(0)9424-9481240 Rev.

FCC ID: VEB-NKRDCMA82 5.6.4 Description of Measurement The maximum total power input to the antenna has been measured conducted as described in clause 5.3 of this document. Through the Friis transmission formula, which is a far field assumption and the known maximum gain of the antenna, the maximum MPE at a defined distance away from the product, can be calculated. Pout * G Friis transmission formula: Pd = 4* *r2 where Pd =power density in mW/cm2 Pout = output power to antenna in mW G = gain of antenna (linear scale) r = distance between antenna and observation point (cm) 5.6.5 Test result Worst case: Antenna Nahfeldkoppler with an antenna gain of 3.7 dBi, Power setting: 18 dBm Channel Frequency Max power output to Antenna Power density Limit of power No. antenna gain density (MHz) (dBm) (mW) (dBi) (mW/cm2) (mW/cm2) 36 5180 16.2 41.7 3.7 0.019 1.0 40 5200 16.3 42.7 3.7 0.020 1.0 48 5240 16.8 47.9 3.7 0.022 1.0 Limits for maximum permissible exposure (MPE) Frequency range Electric Field Magnetic Field Power Density Averaging Time Strength Strength (MHz) (V/m) (A/m) (mW/cm2) (minutes) (B) Limits for General Population / Uncontrolled Exposure 0.3 – 3.0 614 1.63 100 30 3.0 – 30 824/f 2.19/f 180/ f2 30 30 - 300 27.5 0.073 0.2 30 300-1500 --- --- f/1500 30 1500-100000 --- --- 1.0 30 f = Frequency (MHz) The requirements are FULFILLED. Remarks: Addition of new antennas would not change previous results. mikes-testingpartners gmbh File No. T34715-00-03AA, page 30 of 47 Ohmstrasse 2-4  94342 STRASSKIRCHEN  GERMANY Tel.:+49(0)9424-94810  Fax:+49(0)9424-9481240 Rev.
