The following restrictions apply when the Flash Sync terminal is in use:
TTL automatic flash exposure control, automatic flash synchronization of the
camera shutter speed, and the viewfinder's flash ready-light indicator do not work.
The only Flash modes possible are Manual Flash Exposure control and Non-TTL
Automatic Flash Exposure control.
The camera's shutter speed for flash sync cannot be set automatically. Set the
shutter speed manually to a slower speed than the synchronization speed
(maximum speed available is 1/180 second).
The flash ready-light indicator does not function; confirm that the flash is ready
with the strobe's own ready-light indication.
