Question about Hörmann Hand-held transmitter HSM 4

The HSM 4 hand-held transmitter from Hörmann operates at a frequency of 40.685 MHz and is only compatible with Hörmann operators, not those from other manufacturers. The Tedsen SKX1LC, on the other hand, operates at a frequency of 433.92 MHz. Due to the different frequencies, these two hand transmitters are not compatible.

Code synchronisation between the Hörmann HSM 4 hand-held transmitter and the Tedsen SKX1LC is therefore not possible. The Tedsen SKX1LC is programmed by programming a functional hand-held transmitter with the same frequency and coding, which does not work with the Hörmann hand-held transmitter.
