Canon 577 G - Manual (Page 14)

SETTING THE
ASA FILM
The sensor must know the ASA film
speed to give correct exposure.
Make sure it is set correctly on both
the camera and the flash. To set it on
the 577G, rotate the calculator dial
until the film speed index is aligned
with the ASA speed which corres­
ponds to that of the film in the
camera.

Normal Flash Photography: Make
sure the 577G's slow-sync
AUTO/MANU switch is on
“AUTO”. Except for “B” (Bulb), the
AT dial and AE mode selector may
be on any setting and the shutter
speed will switch to 1/60 sec., the
flash synchronization speed,
automatically

control of exposure duration just
as you normally are with “B”.
