For multiple flash photography usi ng Nikon Speed lights, 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 coefficie nts (numbers shown in parentheses below) for all of the speedlights used at anyone time does not exceed 20 at 20°C/6soF (13 at 40°C/104°F).
If you are unable to take a second picture, disconnect master speed light from the F4, or turn each of the speedlights off and on once.
In certain cases, due to static electricity or poorly loaded batteries, the F4'smicrocomputer may turn the camera off, even with fresh, properly installed batteries. For the same reason, fi lm 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.
The Nikon autofocus SLR system is designed based on the premise that any of its components, such as the F4,
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.
