Pacific Crest Corporation FCC ID: KEAADLP 4 FCC §2.1091 – RF Exposure Information 4.1 Applicable Standards According to FCC §2.1091 and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. Limits for General Population/Uncontrolled Exposure Frequency Electric Field Magnetic Field Averaging Power Density Range Strength Strength Time (mW/cm2) (MHz) (V/m) (A/m) (minutes) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 2 1.34-30 824/f 2.19/f *(180/f ) 30 30-300 27.5 0.073 0.2 30 300-1500 / / f/1500 30 1500-100,000 / / 1.0 30 f = frequency in MHz * = Plane-wave equivalent power density 4.2 MPE Prediction Predication of MPE limit at a given distance S = PG/4πR² Where: S = power density P = power input to antenna G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna 390 ~ 430 MHz Band: Maximum peak output power at antenna input terminal (dBm): 45.6 Maximum peak output power at antenna input terminal (mW): 36307.805 Duty Cycle: 50% Maximum Corrected output power at antenna input terminal (mW): 18153.9025 Prediction distance (cm): 120 Prediction frequency (MHz): 390.05 Antenna Gain, typical (dBi): 5.0 Cable loss (dB): 1.0 Maximum Antenna Gain+ Cable Loss (numeric): 2.512 2 Power density at predication frequency and distance (mW/cm ): 0.252 2 MPE limit for uncontrolled exposure at prediction frequency (mW/cm ): 0.26 Report Number: R1008242-90 Page 12 of 92 FCC Part 90 Test Report

Pacific Crest Corporation FCC ID: KEAADLP 430 ~ 473 MHz Band: Maximum peak output power at antenna input terminal (dBm): 45 Maximum peak output power at antenna input terminal (mW): 31622.777 Duty Cycle: 50% Maximum Corrected output power at antenna input terminal (mW): 15811.3885 Prediction distance (cm): 120 Prediction frequency (MHz): 472.95 Antenna Gain, typical (dBi): 5.0 Cable loss (dB): 1.0 Maximum Antenna Gain+ Cable Loss (numeric): 2.512 2 Power density at predication frequency and distance (mW/cm ): 0.220 2 MPE limit for uncontrolled exposure at prediction frequency (mW/cm ): 0.3153 4.3 Result The device is compliant with the requirement MPE limit for uncontrolled exposure. 430-473 MHz maximum power density at the distance of 120 cm is 0.220 mW/cm2 (Limit 0.315 mW/cm2). The 390-430 MHz maximum power density at the distance of 120 cm is 0.252 mW/cm2 (Limit 0.26 mW/cm2). Report Number: R1008242-90 Page 13 of 92 FCC Part 90 Test Report
