making changes with TAG function in ACP

I am wondering how to change settings in the TAG tab.
Beep off should be BEP:0 > SET but that doesnt work, also not after REFRESH and also not after export settings and restart.
I would also like to know how to change the SSID name. in TAG you have to fill in NAM: ‘asci name’. To change alphabetic in asci is duable with an online tool, but again. Doesnt work.
Anybody know how to do that?
