Radio door opener XT2 868 SLH LR, 2 channels, 868.35 MHz, white - FAAC 787009

Usage frequency 868.35 MHz.
Coding type: SLH LR technology (FAAC patent).
SLH = SELF LEARNING HOPPING code: the code changes each time the transmitter is used.
An algorithm recognises and validates the signal only of transmitters encoded by the receiver. Advantages: cloning almost impossible.
Possibility of replicating the coded transmitters, even remotely from the receiver, with the patented SELF LEARNING system (transmitter to transmitter), simply by pressing the buttons according to a specific sequence.
LR = LONG RANGE: the transmitters are able to cover almost DOUBLE the current distance thanks to a further FAAC patent on the electronics; the SLH LONG RANGE transmitter, each time the control buttons are pressed, in real time performs a sensing of the surrounding environment (e.g.: hand position, presence of electrical disturbances, etc.) and automatically reconfigures the electronics maximising, with each transmission, the radiated power.
Fully compatible with previous SLHs.
