This light flashes when the pack is automatically dumping excess energy after a power-level adjustment. Press the Test Button to: Flash Power Control The power pack is divided into two channels, A and B, and each is fitted with one head socket. An LED display for each channel indicates the available power in watt/seconds available at the head fitted to that channel. A single Overall Power Selector reduces the pack's total power by one or two f/stops and individual Channel Variator controls reduce each channel's power by a further three f/stops in 1/3-stop steps. The Overall Power Selector has settings for both Asymmetric (A/B) and Symmetric (A+B) modes. The selected power in Asymmetric mode is available independently from each channel whether or not any head is fitted in the other channel. The power available is controllable by using the appropriate Channel Variator and the associated display. The full selected power in Symmetric mode is only available from Channel A, providing that no head is fitted in the Channel B socket. [. . . ] Turn the Audio Switch On with the rocker switch.
