This is something which is driving me mad! I can't successfully set up fire groups for the SRVs Dual Repeaters and Data Scanner, nor can I cycle through the groups that I set up. Basically I want to have the guns shooting in Combat mode and then when I change to scan mode select a group which brings the Data Scanner into action when I press the primary fire button. Cant get it to work. I have to go into Fire Groups, remove the dot from the Repeaters, set 1 on the Data Scanner so that it will operate. Then the reverse process to get the Repeaters active again. Must be an easier way!
