Regulations and Standards The Model MQB37W meets the statutory requirements of the following Countries in Table 2. New released standards will be analyzed and if necessary testing performed and Table 2 updated. In regards to Europe differences between Table 2 and the DoC could be due to non-technical changes in revisions to the standards, which do not require further testing. 2.Table Standards applied for homologation release testing Country USA / Canada Japan Europe Korea Applicable standard / regulation RF test according FCC Part 15.231/RSS-

Environment mount position The MQB BCM is a component, which is mounted in the car during car manufacturing. Mounting position in the car This part is not reachable by the user as it is a part of the chassis system, covered by the interiorsurface of the car. User manual is in this meaning not applicable for this product. Creating a user manual is the responsibility of the vehicle manufacturer. The OEM describes in the User Manual all important functions for the end customer for error-free operation of the BCM. Robert Bosch provides the OEM with technical information on request. The BCM Equipment cannot be operated stand-alone in its intended use. For intended use of the BCM Equipment a data connection to the host vehicle is required. The BCM equipment is not available to the end user. The equipment is manufactured by Bosch and sold to the relevant vehicle manufacturers. Damaged BCMs on a vehicle can only be replaced by the vehicle manufacturers authorized repair workshops as calibration and adjustment with dedicated tools is required after the replacement. The BCM is no retrofit device that is freely available and could be installed on the vehicle by the end-user after purchase.

General Description The radio frequency transceiver is part of a body computer ECU. The ECU incorporates several HW-
inputs and HW-outputs, which monitor and control body computer functionalities in a car (e.g. light control and central door locking). The ECU consists of a plastic housing, PCB, electronic components and connector pins. The radio frequency transceiver functionality will be explained in more detail in the below documented sections. 5. HW Interface The radio frequency transceiver is supplied via the specified connector pins. The antenna of the radio frequency transceiver is a PCB-edge antenna, which is incorporated in the PCB of the ECU. a.

Radio Frequency key data The radio frequency transceiver has the following key data:
Effective radiated Power: <= -6dBm (Band 433MHz to 434MHz 10mW) Issue Date: 28.02.2019 Dept.: AE-BE/PAN3 Name: Mario Heimann Page: 7 von 11 Robert Bosch GmbH Mittlerer Pfad 9 70499 Stuttgart-Weilimdorf Germany All rights held by ROBERT BOSCH GMBH, including applications for patents and property rights and the right of disposal, such as to reproduce or pass on to third parties TCD Part Homologation MQB37W BR20 F005VS0326 Homologation: Radio Frequency Transceiver 10. Functional description The radio frequency transceiver is part of a remote keyless entry system of a vehicle central door locking system. This vehicle central door locking system consist out of Remote control key with UHF transmitter (NOT part of the MQB BCM) Radio frequency transceiver with PCB-Antenna (part of the MQB BCM) Door ECU, which can drive the car door locks to lock or unlock the car (NOT part of the MQB BCM) Door locks for the central door locking functionality (NOT part of the MQB BCM) The transceiver has a self-polling mode and is permanently scanning for valid key data, with matching characteristics.
(Note: This data are typically received, when a valid remote control key is in range and one of its push-buttons is pressed.) When the data are matching the characteristics, the transceiver will hand over this data to the micro controller of the MQB BCM. With the help of this micro controller, it is validated, whether this data have been transmitted from the authorized remote control key. When the validation was successful, the MQB BCM will send this information via a CAN-network to the door ECU. This door ECU will drive the connected door lock according to the wish of the operator, who pressed the push button of the remote control key. Hence the doors will be locked or unlocked. The MQB BCM needs to be programmed by the OEM, after installing the ECU into the car. Once programmed, the transceiver is operable directly after applying power to the connector pins. 11.

The radiated output power of the device is far below the FCC radio frequency exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact during normal operation is minimized. 3) For a portable device where routine evaluation is required and Body-worn use with a specific accessory Radiofrequency radiation exposure Information:
For body worn operation, this phone has been tested and meets the FCC RF exposure guidelines when used with the (manufacturer name) accessories supplied or designated for this product. Use of other accessories may not ensure compliance with FCC RF exposure guidelines. 4) For a portable device where routine evaluation is required and Body-worn use without a specific accessory, but with a justified distance. Radiofrequency radiation exposure Information:
For body worn operation, this phone has been tested and meets FCC RF exposure guidelines when used with an accessory that contains no metal and that positions the handset a minimum of (specified distance) from the body. Use of other accessories may not ensure compliance with FCC RF exposure guidelines. 5) For a portable device where routine evaluation is required and Body-worn use with future manufacturer designed accessories: (e.g. Cellular phone, ) Radiofrequency radiation exposure Information:
For body worn operation, this phone has been tested and meets the FCC RF exposure guidelines when used with a (manufacturer name) accessory designated for this product or when used with an accessory that contains no metal and that positions the handset a minimum of (specified distance) from the body. 6) For a portable device where routine evaluation is required and Body-worn use has been tested touch to the phantom.
