Nikon F 4 - Page 110

For multiple flash photography using Nikon Speedlights,
if the electric current in the sync circuit exceeds a cer-
tain level, you may not be able to take a second picture
after taking the first. Take care that the combined total of
the coefficients (numbers shown in parentheses below)
for all of the speedlights used at any one time does not
exceed 20 at 20°C/68°F (13 at 40°C/104°F).
SB-24 (1) SB-23 (4) SB-22 (6) SB-21 (4)
SB-20 (9) SB-19 (2) SB-18 (16) SB-17 (4)
SB-16 (4) SB-15 (4) SB-14 (1) SB-12 (1)
SB-11 (1)
If you are unable to take a second picture, disconnect
master speedlight from the F4, or turn each of the
speedlights off and on once.
The Nikon autofocus SLR system is designed based on
the premise that any of its components, such as the F4,
F-801/N8008* F-501/N2020**, F-401s/N4004s**, AF Nikkor
lenses, TC-16A Autofocus Converter, Nikon speedlights
and Nikon accessories will be used integrally, with one
another.
AF Nikkor lenses electronically communicate all the
necessary information required for perfect operation
within current and future Nikon autofocus SLR systems.
Nikon does not assume responsibility if malfunctions or
damage occurs to the F4 when lenses and/or accesso-
ries of other makers are used with it. For these reasons,
we recommend the use of AF Nikkor lenses and Nikon
system accessories.

In certain cases, due to static electricity or poorly loaded
batteries, the F4's microcomputer may turn the camera
off, even with fresh, properly installed batteries. For the
same reason, film may not advance properly. In each of
these cases, to resume operation, simply turn the power
OFF and turn ON again, or remove batteries and install
again.
Nikon cannot be held responsible for any malfunction
resulting from the use of the camera other than as
specified in this manual.
The shutter cannot be released while camera back is
open. If for some reason you need to release the shutter
with the camera back open, consult a Nikon service
facility. Also, be sure to set the shutter speed to 1/250
sec. or higher; do not set to 1/125 sec. or slower.
