Power distribution charts are provided in the next section of this manual and on the side of each power supply. When we refer to ratioing, we are describing the levels of power output from the power supply to the light units only. These power output ratios do not mean that the light falling on the subject will be at that same ratio. This will only occur if the light units are the same and have the same flash tube, reflector, cable length, light control accessories, are at the same distance to the subject, and there is no overlap of lighting on the subject, etc. Power output ratios are only offered as a guide to help you determine your lighting arrangements. *Not available on 405 power supplies. 5 instructions and information General Instructions and Information Speedotron power supplies. Failure to do so may cause the power supply to intermittently misfire. 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 LV. 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 LV; 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 LV power supply will automatically discharge its storage capacitors. Unplug power cord from outlet, then disconnect light units from power supply. 7 2403CX LV · power supply 8) Remote -- for use with optional Remote Variable Power Control (#11237) to allow exposure bracketing from the camera position.
