It is forbidden for users to change the device privately. 1. 1.1Data protection, network security, and wireless aspects 1.1 In order to consider the security aspects of data and software of products and components installed in vehicles, the product properties of related measures are described here. 1.2 Safety and Warning 1.2 The product is provided and approved for a rated voltage of 12 volts. Short circuits must be securely prevented, even in the event of a fault. Creeping short-circuits in particular lead to high arc energies that cannot be switched off by conventional melting fuses. If other rated voltages are present in the vehicle (e.g. 24/48 V for example in hybrid vehicles, or 400/800 V in electric vehicles) we recommend that safety precautions are taken in the vehicle itself (e.g. additional insulation of high voltage lines and the use of edge protectors when passing through sharp-edged areas, in order to prevent short circuits to inputs/outputs of our device, e. g. to loudspeaker lines). 12 Wuxi Auto-Link World Information Technology Co., LTD 24/48 V 400/800 V

The product is intended, and has been approved, for installation and operation in automobiles, motor homes, commercial vehicles. 12 Only connecting cables and external devices that are appropriate for the device in question may be used (e.g.: proper current carrying capability, proper EMC shielding, flammability verified with appropriate certificates). Compliance with the applicable standards can no longer be guaranteed if the device including the software is modified without the agreement of Bosch and Autolink. EMC 1.3 Material safety requirements 1.3 All materials shall be selected according to design, durability and other performance requirements (see drawings and standards). Prohibited and hazardous substances shall meet the GB/T30512-2014 . For plastic, rubber and thermoplastic elastomer parts, there should be material identification / recyclability identification.

It is forbidden for users to change the device privately. 1. 1.1Data protection, network security, and wireless aspects 1.1 In order to consider the security aspects of data and software of products and components installed in vehicles, the product properties of related measures are described here. 1.2 Safety and Warning 1.2 The product is provided and approved for a rated voltage of 12 volts. Short circuits must be securely prevented, even in the event of a fault. Creeping short-circuits in particular lead to high arc energies that cannot be switched off by conventional melting fuses. If other rated voltages are present in the vehicle (e.g. 24/48 V for example in hybrid vehicles, or 400/800 V in electric vehicles) we recommend that safety precautions are taken in the vehicle itself (e.g. additional insulation of high voltage lines and the use of edge protectors when passing through sharp-edged areas, in order to prevent short circuits to inputs/outputs of our device, e. g. to loudspeaker lines). 12 Wuxi Auto-Link World Information Technology Co., LTD 24/48 V 400/800 V

The product is intended, and has been approved, for installation and operation in automobiles, motor homes, commercial vehicles. 12 Only connecting cables and external devices that are appropriate for the device in question may be used (e.g.: proper current carrying capability, proper EMC shielding, flammability verified with appropriate certificates). Compliance with the applicable standards can no longer be guaranteed if the device including the software is modified without the agreement of Bosch and Autolink. EMC 1.3 Material safety requirements 1.3 All materials shall be selected according to design, durability and other performance requirements (see drawings and standards). Prohibited and hazardous substances shall meet the GB/T30512-2014 . For plastic, rubber and thermoplastic elastomer parts, there should be material identification / recyclability identification.
