South Galaxy G1 Plus input call sign

If I want to change my South Galaxy G1 Plus from a rover to a base, I have found all of the menu areas to select base operation and set up radio frequencies.

I can not find anywhere to enter a call sign and a time between transmission of the call signs. Is there a menu area to do this that I am missing? If so, where is that menu?

Hi, friend, could you let us know where are you located? we may find our nearest support to contact you directly, thanks
