Set the FJ-X2m trigger to "Nikon". To enable HSS for Nikon cameras, use the in-camera menu system to set the Flash Sync Speed setting to “1/250s (Auto FP)” or "1/200 (Auto FP)". Your Nikon camera will then automatically adjust your trigger and strobe into the High-Speed Sync setting when you advance the shutter speed above normal synchronization speeds.
Standard in-camera menu settings apply. Silent shutter, e-front curtain off, red eye reduction off and ensuring that your FJ-X2m is aligned properly to the Nikon hot shoe and engaging the multi-pin mechanism is critical for proper communication and preventing misfires. Some Nikon bodies will require you to toggle the menu "apply settings to live view" to "off" to allow your on camera screen to brighten as a standard optical view finder when the FJ-X2m trigger is attached.
Initial communication for some Nikon bodies (not model related) experiencing connection issues may be solved with a small adjustment to the hotshoe mounting position for your FJ-X2m. On these bodies, nudge the trigger slightly back from the front of the camera's hotshoe to allow the locking pin of the FJ-X2m to engage properly. Engaging the Nikon creative lighting system may override and control the FJ-X2m trigger settings.
