Ready-Ught Warning Functions
To prevent errors, the ready-light inside the camera's
viewfinder blinks in the cases listed below. When blink-
ing occurs, check the S8-22's flash mode selector
setting, the camera 's shutter speed/mode selector set-
ting or film speed setting and adjust as necessary.
1) When S8-22 is set at TTL with cameras other than
Nikon F-501/ N2020, F-401/N4004, F-301lN2000,
FA, FE2 or FG.
Reset S8 -22's flash mode selector to A1, A'2 or M.
2) When using the FA, FE2, or FG to perform TTL auto-
matic flash photography with the camera 's shutter
speed .dial set at a mechanical setting (M250, M90
or 8). Reset shutter speed dial to another shutter
speed setting. For M250, M90 or 8 setting, reset
S8-22's flash mode selector to A1 , A2 or M.
3) When performing programmed TTL auto or TTL
auto flash operation with a camera film speed set-
ting beyond the usable range . Use film within the
approp.riate range for TTL auto flash photography
(ISO
2~
to 400 with the F-40 1/N4004, FA, FE2 or
FG; ISO 25 to 1000 with the F-50 1/N2020 or F-301/
N2000). With the FA, ready-light also blinks when the
film speed setting on the camera is near ISO 12.
4) When shutter speed set on the FE or FM2 is faster
than the flash sync speed. Set the shutter speed to
the flash sync speed or slower one.
5) With the Nikon F-401/N4004, when the built-in flash
and S8-22 are OFF, and when the camera detects
flash is effective, the ready-light in the camera's
viewfinder blinks when the shutter release button is
lightly pressed.
With the S8-22 in TTL, A1 or A2 mode, if both view-
finder ready-light and S8 -22 ready-light blink after
taking pictures (to warn that lighting might have been
insufficient for correct exposure), confirm subject is
within the flash shooting distance range and,. if neces-
sary, use a wide aperture or move closer to the subject.
With the Nikon F-401/N4004, for scenes where the
background is extremely bright, the ready-light may not
blink after the shot, even if flash is insufficient for cor-
rect exposure.
With weak batteries, ready-lights blink to indicate insuf-
ficient flash power, even if the subject is within the
shooting distance range ; replace batteries with a fresh
set.
