Date 27-05-2019 To whom it may concern, On behalf of our customer Endress+Hauser SE+Co. KG, we hereby declare the following device: FCC ID : LCGVU121 IC : 2519A-VU121 Brand : Endress+Hauser Model : VU121 The EUT has one transmitter (BLE). The RF exposure assessment is based on the BLE mode. The EUT is considered as ‘Mobile’ use. The EUT has a maximum rated output power in BLE mode of 2.4 mW in the frequency range of 2402 – 2480 MHz which means that the worst case prediction of power density (100% reflection) at 20 cm distance (worst case) can be calculated as follows : EIRP S= 4 * π * R2 (power density without reflection) 22 * EIRP S= 4 * π * R2 (power density with 100% reflection) 22 * EIRP EIRP (mW) 2.6 ___ S= 4 * π * R2 = π * (20cm)2 = π * (20)2 = 0.0021 mW/cm2 (limit =10 W/m2 is 1.0 mW/cm2) This means that the equipment is in compliance with FCC KDB Publication 447498, 47 C.F.R. §1.1310 and §2.1091 fulfils the requirements of RSS-102 Issue 5 Section 2.5.2. stating: at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1.31 x 10-2 ƒ 0.6834 W (adjusted for tune-up tolerance), where ƒ is in MHz. For this EUT the this calculates to: 1.31 x 10-2 (2402 0.6834) = 2.68 W. The EUT’s maximum rate output power (EIRP) of 2.6 mW is within this requirement. Note: For conservativeness, the lowest frequency is used for calculation. Best regards, TÜV Rheinland Nederland B.V. R .van der Meer, Test Engineer
