When using the Hot-shoe,
be sure to put an appropriate
Safety Cover over the X-sync
terminal so that you won’t
receive a high voltage
electric shock if the terminal
is accidentally touched. (A
Safety Cover is put on the
X-
sync terminal when the
camera leaves the factory.)
1. When using an electronic flash,
plug the synchronization cord into
the Sync Teminal and set the Shutter
Speed Dial to
1/60
sec. or slower.
