Remember...just because there isn't a TG4000 in the list to select from doesn't mean you can't specify it manually. You could do this a few ways:
1) Define a 4000 under the MIC Settings.
2) Under Settings/Shortcuts define one for group call 4000.
[My preferred way]
3) On the M1KE, Hit Set dst by pressing and holding the down key. Set and go to 4000 that way. Then go back in and save 4000 as a favorite under the same menu area.
