[. . . ] 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. Press the Push to Flash button to discharge unit. When increasing power (rotating knob from -1 stop to Full, for example) it is immediately increased to the light units. Rotating the Variable Power Control does not change the output of the model lamps. Their output is controlled by the Variable Model Lamps Controls, one control for each power channel. Rotating the knobs immediately adjusts the output of the model lamps. This way, model lamp output can be matched to the light units, and lighting ratios are easily visualized. When disassembling the system, turn Power switch to the off position. This flashes all light units connected to the Model 1205CX LV / 2405CX LV. Do not push the Push to Flash switch before turning power supply off. Unplug power cord from outlet, then disconnect light units from power supply. 7 1205CX LV / 2405CX LV Description of Controls Note:Instructions apply to all versions of 1205/2405 power supplies.
