Initialising a motor vehicle anti-theft system |
摘要 |
An inquiry signal is emitted by way of one or more interior antennae of the motor vehicle. The transmitting power of the emitted inquiry signal is altered for so long until a portable transponder only just receives the inquiry signal, if the transponder is in a fixed position which is defined beforehand. The transmitting power set in this way is stored for the operation of the anti-theft system.
