                TeleMega provides explicit support for an external pyro
                battery. All that is required is to remove the jumper
                between the lipo terminal (Bottom 3) and the pyro terminal
-               (Bottom 2). Then hook the negative pyro battery terminal to ground
-               (Bottom 1) and the positive pyro battery to the pyro battery
-               input (Bottom 2). You can then use the existing pyro screw
+               (Bottom 2). Then hook the negative pyro battery terminal to 
+               ground (Bottom 1) and the switched positive pyro battery to 
+               the pyro battery input (Bottom 2). Note that you must include
+                a switch between the pyro battery and the board for safety,
+                as the on-board power switch circuit only supports the primary
+                battery!  You can then use the existing pyro screw
                terminals to hook up all of the pyro charges.
