	Use instructions The Tristar 320TZB is an semi-automatic flash with basic ranging capability. This ranging ability is similar to the "A" mode on a Nikon SB-800 or SB-600 photo flash. The range selection is made with the slider switch on the front of the unit (figure 1). The four settings correspond to the manual computer on the top of the unit (figure 2). Figure 1 - Front controls of the Tristar 320TZB, both full power and automatic Figure 2 - Top manual computer for the Tristar 320TZB photo flash. Slide is only for you and doesn't affect flash settings at all. Full power To use this flash at full power, set the slider switch on the front of the unit to M. This will fire the flash at maximum power. Automatic mode Look on the top of the Tristar 320TZB unit. You will see a slider switch. This switch does nothing to the internal operation of the flash. It is only there for you to figure out how to set the flash unit. Move the slider switch until you see the ISO that matches that of your digital camera or the ISO of the film you are using. In figure 2, the flash is set to ISO 100. Now you will see three colored arrows. These colors correspond to the colors on the front of the flash. This is where it can get a little tricky, but with practice, you will be able to operate this flash with ease. Automatic mode easy Look at the F/No. indicater just under the top slider (figure 2). Set your camera lens to the f-stop indicated under the cyan/blue arrow. Move the slider switch on the front of flash unit to the cyan/blue position. You now will be able to successfully use the flash with subjects in the autodistance range of 5-37 ft or 1.5-11 meters. Anything subject closer will be overexposed and any subject farther away will be underexposed. When you fire the flash, the Auto Check light on the back of the unit will illuminate, indicating a good exposure. If the green light does not come on, the flash thinks it did not provide enough light to the subject. That's it! Automatic mode involved You can either operate in a f-stop approach or a subject distance approach with this flash. I suggest using the f-stop approach. F-stop thinking is more versatile, as it's really difficult to estimate subject distance, adjust the front flash slider and then change you camera f-stop. Subject distance is something when you have plenty of time to fiddle. If you wish to use a different f-stop, chose the f-stop you want, then look on the top of the Tristar 320TZB to find the f-stop you are operating with. Once you've found it, adjust the top slider to to match the ISO of your camera/film. You can now see which color arrow the flash suggests using. Set the front switch to that color position. You now can shoot subjects that are in the range above whichever color you have chosen. This flash is easiest to use in the cyan/blue settings for all but the closests subjects when shooting at low ISO speeds and when you have a faster lens (low f-stop accepts more light). Note Be aware that the hotshoe voltage is quite high, though still within the 250V maximum specified by a Nikon D200. See this article about flash hotshoe voltage.
