2AVXWWSBRS001Wireless Seat Belt Reminder - Seat Unit

Manual 2K7959760A Date: 07/23/2020 version 0.2 page1 of 3 1.1.1 Frequencies Bluetooth Low Energy f=2402MHz ÷ 2480MHz 1.1.2 Function description Image1 S-SG The S-SG in the car seat is powered by a built-in battery. The mechanical construction enabling the exchange of the battery without special tools or soldering. The S-SG sends the status information of the belt buckles and the status of seat occupancy sensors. The information is sent either at the time when a change is detected, or every 25 seconds cyclically. The reading period of the AD value of the resistance circuit in the seat occupancy sensor is 200 ms, it can be changed by software. The battery voltage is read once a day. The algorithm for the evaluation of the battery status then sends the current value in every Bluetooth message. The S-SG is contacted only at the time of data transmission with the F-SG, otherwise it is in the (low power mode) power saving mode. Manual 2K7959760A Date: 07/23/2020 version 0.2 page2 of 3 1.1.3 Error conditions The device can not detect faulty state of belt buckle, the analog value is not measured at the entrance, there is only detected a logic signal. The device detects error state values at the inputs to determine the seat occupancy. The following error conditions are detected: Table1 Limit values of the sitting sensor error signal value tolerance description delivery status After switching on the device, the value is not read (not used in practice) Low resistance value R <60 Ω 60 ± 4 Ω The wires are connected or shorted to GND Seat occupied 60 Ω <= R <= 250 Ω 60 ± 4 Ω 250 ± 8 Ω Correct value is expected Average resistance value Is not used unexpected invalid resistance Vacant seat 250 Ω <R <= 620 Ω 250 ± 8 Ω 620 ± 15 Ω Expected valid value High resistance value R> 620 Ω 620 ± 15 Ω Wires broken or high resistance Image2 Error detection algorithm on the input of the occupied seat Manual 2K7959760A Date: 07/23/2020 version 0.2 page3 of 3 1.1.4 Temparature or voltage operating range temperature: -40C ÷ +80C voltage: battery 3,3V; CR2477 The manufacturer of this radio equipment declare that devicecomply with the ISED regulation: IC: 25953-WSBRS001 NOTICE: This device complies with Part 15 of the FCC Rules [and contains license-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canada’s licence-exempt RSS standard(s)].

FCC SAR exemption letter 19-1-0055001T17a-C1 FCC SAR exemption letter according KDB 447498 D01 v06 For AEV spol. s.r.o. , wireless Seat Belt Reminder - seat unit with HW version 036 and SW version 159. Declared minimum distance to human body according to customer = 5 mm according to external document “MPE Information Requirements_Sensor_20200805.pdf” provided by customer. According to KDB 447498 D01 General RF Exposure Guidance V06 SAR testing can be exempted if the following exclusion threshold are met: P threshold calculation based on external document “MPE Information Requirements_Sensor_20200805.pdf” provided by customer. P threshold = Maximum Rated Conducted Output Power (dBm) + Tune-Up Tolerance - Maximum Path Loss to Antenna P threshold_DUT = 1 mW * 10 ((-11.2 dBm + 1.4 dB)/10) = 0.1047 mW < 10 mW @ 2450 MHz with 5 mm test separation. The user manual must list the given usage position. The current version of the FCC SAR exemption letter CETECOM_TR19_1_0055001T17a_C1 replaces the FCC SAR exemption letter CETECOM_TR19_1_0055001T17a dated 2020-08-03. The replaced FCC SAR exemption letter is herewith invalid. ____________________ __________________ Dipl.-Ing. Ninovic Perez B.Eng. Martin Nunier
