Ok, this here is the manual range input seminar where y'all are gonna learn to abuse the equipment even more than the Dick O'Kane tactic. Let's take a look at the right dial of the TDC, where all the input takes place. First press the range button to select range and bearing. Usually the next thing you do would be to push the stadimeter button.
There we go. The pointer is aimed at the clear plastic with the indicator line on it. We can grab it with the mouse and rotate it to set the range. Here it is set to 1200 yards. Just release and hit the red send range/bearing button to send the range to the TDC. DON'T FORGET YOU ARE ALSO SENDING THE BEARING YOUR PERISCOPE IS POINTING TO RIGHT NOW!!!!!! You have been warned. If you get burned, blame Ducimus. If you like it, send your tuition to me.
