[QUOTE="WayneF, post: 643524, member: 12496"] Welcome to the forum Nicole. I'm not sure of your full meaning. Is one problem that the internal flash is triggering when you don't want it to? That answer would be "Don't use camera Auto mode with the external flash." In Auto mode, the internal flash triggers whenever the camera thinks it's dark enough to need flash, which would be about all the time indoors. But another problem is that a manual light like the B800 can never work with a a camera in Auto mode, or with Auto ISO. You have to set a specific power level in the manual flash, and it cannot react to any auto change the camera might care to make. Auto ISO mode must also be turned off with a manual flash. So with manual studio lights, the correct mode is camera Manual mode, to prevent that internal flash, and to prevent the camera from making arbitrary auto changes, and to be able to set the correct camera settings you want to use. Auto ISO must be OFF too (the manual flash cannot respond to it). Then in camera A,S,P or M modes, the internal flash will never trigger unless you open its door, and then if opened, it will always flash (in A,S,P or M mode). The B800 has two ways to trigger it. It has an internal optical slave, and will trigger in sync when it sees any other manual flash fire. From your description, I am suspecting this is happening. The radio trigger and sync would not even be needed in that case. Or, plugging a sync cord into the B800 will disable that optical trigger, and then it triggers only when the sync cord triggers it. The cord might run to the radio trigger receiver, or it might be plugged directly into the camera (if a PC sync port like the Nikon AS-15 were added to the camera hot shoe). So one way to interpret what you said is the sync cord to the radio receiver is not making connection with the B800 sync jack, and the internal flash must be triggering the optical slave (but which it could not do if a cord is plugged into the B800 correctly). One possibility is that the sync cord used is somehow not making the right connections. I have seen other complaints about that. One very good try would be to replace the triggers sync cord with the sync cord that came with the B800. It should easily plug into the radio trigger, and also work well that way. That certainly would be a way to test for this case. If necessary, it is easy to test the sync cord and B800 by plugging the cord into the B800, and then with a straight or safety pin, or the end of a paper clip wire, simply short the PC connector end, center pin to its round shell. This is very safe (except it will flash, so aim it away from your eye), and the short is the routine way that the flash is triggered. If that works (if the B800 triggers), then cord and B800 are obviously OK and doing their job. Or possibly the radio trigger units are not working or are not set up right? [/QUOTE]
