Modem Signal LED

Hi All.

I recently installed one SXT LTE modem at home.

At the beginning the wole 5 leds were off ..later one i discovered that those leds must be activated on the webconfig.

So after that, all the leds are on but even with different threshold from led1 to led 5 …all leds are on…

THe signal strenght is aroudn 89-90 db..but event the led 5 threshold is set to -51db is always on..

Anybody can explain me why? I would lik to use those leds to better fine tune the antenna position..but like this is basically impossible.

THanks for your help.

Maurizio.
