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. 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. The 2403CX power supply will automatically discharge its storage capacitors.

(With both 800Ws and the 400Ws switches in combine, 2400Ws is available through any of the six Light Unit Outlets, divided equally. See diagrams on the side of the power supply and page 15 for detailed examples of the ratio system). 5) Variable Power Control -- simultaneously controls power of all three channels, with ten positions down to -3 stops (1/8 power). Power ratios among the light units are unaffected since there is a proportional change in all power levels. 7)Charge/Ready/Push to Flash -- red Charge light is illuminated whenever the power supply is charging up or down to the selected level. Green Ready light is lit whenever the 2403CX is fully charged to the selected power level. Push to Flash button is for manual triggering of flash for testing or open flash application. 8) Remote -- for use with optional Remote Variable Power Control (#11237) to allow exposure bracketing from the camera position.
