| 摘要 |
The invention concerns a method for enabling an apparatus (15) to operate only after detecting with receiver means (11) located proximate to said apparatus, a signal transmitted by portable transmitted means (1), which consists in no longer taking into account detection by the receiver means (11) of the signal transmitted by the transmitting means (1), after activating presence sensing means (22) provided proximate to said apparatus, or integrated in said apparatus. Once activated, the presence sensing means (22) neutralise the transmitter/receiver device (1, 11) and the apparatus can operate normally without being perturbed by possible statics or accidental losses of signal. The inventive method and device are applicable to an antitheft safety device for a motor vehicle.
