Antenna alignment tool on LHG 5AC - is that feature alive?

Hi everyone, I tried to use alignment tool on LHG 5 AC as shown on that video: https://www.youtube.com/watch?v=6_D91n9iWO8
However my antennas did not make a single sound. Am I doing something wrong, or this feature does not work?

LHG 5AC don“t have beeper

Ah, a pity, aligning with that beeping looked like fun! Thanks for the info :slight_smile:
