| ANOTACE "ČSN ETSI EN 303 447 V1.3.1 The present document specifies technical characteristics and methods of measurements for Robotic Mowers with Inductive loop systems (RMI) operating within the frequency range 100 Hz to 148,5 kHz. The present document covers the following RMI systems: - RMI1 systems: RMI systems without receive only mode - RMI2 systems: RMI systems with receive only mode NOTE 1 - In RMI1 systems the robotic mower is not able to restart automatically if the boundary signal comes back after the loss of the boundary signal (safe mode, see clause 4.2.2.3), while in RMI2 systems the robotic mower is able to restart automatically after the boundary signal is back. This differentiation has been introduced to cover receiver spurious emissions for RMI2 systems. These radio equipment types are capable of operating in all or part of the frequency bands given in table 1. NOTE 2 - The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU [i.3] is given in Annex A. The present document only covers RMI systems with antenna sizes smaller than 1,67 km, see CEPT/ERC/REC 70 03 [i.1], Annex 9. NOTE 3 - The antenna size is described by the distance between those two points on the antenna that have the largest distance between them (e.g. for a rectangle shaped antenna the largest diagonal; for a circular shaped antenna the diameter)." | ||
