(The top position is marked as “Full”). If the light is already on, cycle through the settings until you get back to the Full setting. When the light first comes on, the power setting will be flashing on the digital readout. While the display is still flashing, change the unit power setting with the up and down buttons. This will allow you to change the modeling lamp output between minimum (display will read 10) to full (display will read 60) but will not affect the flash tube setting. Once you release the power selector button, the display will revert to your current flash tube setting.In the proportional setting, the modeling lamp output changes relative to the power set for the flashtube. As you adjust the flash tube power, the modeling lamp power will automatically increase or decrease in proportion to flash tube power.
