Because of these three factors, the ready-light may
blink to indicate that the light output was insufficient
for correct exposure even if the subject was within the
coupling distance range.

Speeds
of
1/500 second, 1/250 second, and 1/125 second cannot be used because the sync shutter speed is 1/90 second
or
slower.
c==J
= Proper flash synchronization is not possible because the shutter speed/shooting mode is improperly set.

When
the
camera is set at M90
or
M,
the camera's exposure meter will not operate even if the shutter release button is depressed.
Test
Firing
To
determine whether or not the flash illumination
is
sufficient for a correct exposure, especially when using
the non-TTL automatic mode with distant subjects or
when using bounce-flash photography, test-fire the
flash unit. To test-fire the SB
-102,
turn its power switch
to
"T
EST" after the ready-light
on
the flash unit lights. If
the ready-light
on
the flash unit begins blinking after
test-firing, switch
to
a larger aperture
(a
numerically
smaller f-number), if possible, or move closer
to
the
subject before shooting.
Th
is
setting also enables you to repeatedly fire the flash
manually with the camera set at B (open-flash firing) to
create multiple-exposure stroboscopic effects or
"pai
nt"
the scene with light. When doing this, discon-
nect the speedlight from the camera or the flash unit
will not fire, even if its power switch
is
set at "
TEST."
(Remove the sync cord
and
replace the camera's flash
28
socket and the flash unit
's
sync socket cover before
entering the water
.)
-After test firing
or
open-flash firing, reset the speedlight's power switch
to
"ON"
or
"OFF."
In
the
TTL
mode, the shutter must be released to test-fire the flash
unit, but
if
there is no film
in
the camera, the ready-light will blink even
if the light output was sufficient for correct exposure.
To
avoid this, place a strip
of
cut film (provided
it
is not too old)
or
a
piece
of
gray paper under the camera's film pressure plate, then
release the shutter.
- Even if two speedlights are connected by the optional Double Sync Cord,
only thespeedlight that is being test-fired will fire.
