Sentry – 4 Button Tx Learn (403)
R 179.00
The SENTRY Learning 4 Button 403MHz Radio Frequency Remote Transmitter is equipped with an internal receiver that has the capability of “learning” or cloning another transmitter’s code when the two transmitters are within proximity of one another and the “learning” method is executed as explained in the product leaflet. This embedded technology means that the user will no longer need to adjust DIP switches on the PCB, cloning of remotes is done by simple button-press sequences and is confirmed to be successfully learned into memory by LED flashing on the transmitter that is receiving the copied code. The method of “learning” the code of one transmitter into another transmitter is simple and takes seconds to accomplish and the learning range of transmitters are intuitive and user-friendly. The Learning 4 Button facilitates the cloning of most of SENTRY’s legacy code protocols such as Binary, Inverted-Trinary, and SMART.
