hi, recently I acquired a vivtar 3500 (zoom thyristor) flash and a Nikon EM camera. I didn't get the manual with it. so I have a few questions on how to use them? On the flash what is the difference between the settings red, blue, orange dots, M, yellow triangle, and EM Is this a variable power flash unit? Is there any other function of the beep sound other than the flash ready signal? I assume that the flash is designed to work with the camera I think I read somewhere that the flash sets the camera shutter speed to M90, is this true? if anybody has used this combination please e-mail me with details what is the green led light for? what does "DM/N" mean? A copy of the manuals for both Nikon EM and the flash is really helpful I will compenstate for any costs involved. Any other source of information is welcome thanks for any response. I would appreciate a direct response to my e-mail thanks ravi !!!!!!!!!!!Happy Holidays!!!!!!!!!!! ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
