NOTE: The dual procedure overlay must be present on the Power Wave power source for the Procedure Selector switch to function. If this overlay is not used, only Procedure A will be selected no matter what position the Procedure switch is in.

Setting the toggle switch to the center “Gun Switch” position permits the Procedure A or Procedure B to be selected by the optional K683-1 Dual Procedure Switch. The K1449-1 Dual Procedure Remote Control can be used with this panel Procedure Switch in any position.
