Set Isolate/Combine switches and Variable Power Control as desired. See the side of the power supply for various ratio combinations. With the Variable Power Control in the Full position, power is determined by the choice of outlets and position of ratio switches. The Variable Power Control simultaneously changes the power level of all three channels. Rotating the Variable Power Control immediately adjusts the power level of the 2403CX. The power supply does not need to be discharged between settings. The red Charge indicator will illuminate. After a few seconds, the green Ready indicator will illuminate and an audible beep will sound. (The beep will not be produced when a very small power change is made. Changing the power level by a third f-stop or so is done very rapidly with the 2403CX; the Ready light will usually remain on) The power supply is now charged to the selected level, and ready to fire. Do not immediately fire the unit on the first use or when the unit has been idle for periods over 3 weeks. Allow several minutes for the power supply's capacitors to form. Push to Flash button may be depressed to verify proper system operation. When Power is on, be sure Ready indicator is illuminated before switching Power or Fast/Slow.
