Radio remote control system operation method e.g. for garage door

摘要

The method involves using a first transmitter which sends coded electromagnetic pulses. At least a second transmitter (10) is used which has an integrated receiver (6) and a microprocessor (3). The second transmitter receives coded signals which are transmitted from the first transmitter. The second transmitter stores the coded signal in an appropriate operation mode as a coded transmission signal. The reception and the storage of a code is blocked in the second transmitter when the second transmitter is in an active transmission state. The transmission of a signal is prevented when the transmitter receives a signal which is above a predetermined signal level.
