I have two TT 705 microphones. They both have two transmit buttons. The 
smaller black button is a latching button (actually I think it is a 
momentary contact button connected to a latching circuit) which can be 
unlatched either by pushing it again, or by pushing the other larger 
grey button. The larger gray (both spellings are in the dictionary) 
button is a momentary contact button which works as a standard 
non-latching push to talk. They also both have a 9V battery compartment. 
I don't have a TT 706, so I cannot what their features are.
