Example:
You intend to make a stroboscopic shot with 7 flash exposures at a frequency of
3 flashes per second.
Procedure:
After having completed the first six settings described in „Setting procedure for
stroboscopic mode“, press the button N and then enter the number of exposures
- in this case 7 - with the „+“ or „-“ button.Then press the button f(Hz),followed
by the entry of the flash frequency - in this case 3 - with the „+“ or „-“ button.
The maximum possible partial light output level is automatically adjusted to 1/16.
The partial light output level can also be manually adjusted to a smaller value.
The values specified in the tables only apply to fully charged NiCad
batteries or to new high power alkaline-manganese batteries. For
batteries that have been used it is necessary to adjust the next
smaller main partial light output level (e.g. adjust 1/16 instead of 1/8)
to ensure that the number of flashes is achieved with certainty.

You have now adjusted the number of flashes = 7 and the flash frequency = 3;
the maximum partial light output level of 1/16 has been adjusted automatically.
Table 6 shows you the aperture to be set on the camera.
