60..........indicates shutter speed is
1/60 second.
F............indicates sufficient charge
for firing flash.
2.8, 9.5...is the aperture set on flash.
Even if you turn the aper­
ture ring to a different
aperture from that set on
the fiash, the viewfinder wili
still show the aperture on
the flash. However, the pic­
ture willl be taken at the
aperture you have set on
the lens.
M...........reminds you that you have
taken the aperture ring off
"A” to set an aperture by
hand.
* With an FL lens, viewfinder infor­
mation on aperture is not aiways
reliable. Make sure the aperture
ring is set to the aperture chosen
on the flash.
• If the AT dial is on “B”, “bu” re­
places shutter speed information
in the viewfinder for both fiash
modes. Automatic fiash control is
possible on “B”.

* The aperture display may be one
half f/stop off the one set on the
flash. This is because the aperture
display is rounded off to half
f/stops; it wiil not affect exposure.
A-1 Warnings
1. Aperture display blinks showing
maximum aperture: means the
aperture set on the flash is pro-
babiy iarger than the lens’
maximum aperture. Set the aper­
ture selection switch to a smalier
aperture.
Be sure to check the
aperture set on the flash if this
happens.
(if the display blinks with an aper­
ture which is the same as the lens’
maximum aperture, exposure will
be correct anyway.)
2. Aperture display blinks showing
aperture of 1/16 to f/32: means
aperture set on fiash
may be
too
smail. Check the aperture set on
the fiash. If it is the same or larger
than the lens’ minimum aperture,
exposure wiii be correct. Other­
wise, set the 577G’s aperture se­
lection switch to a larger aperture.
