Optic S1 Secondary Unit Setting
In M manual flash mode, press < S1/S2 > button so that this flash can
function as an optic S1 secondary flash with optic sensor. With this
function, the flash will fire synchronously when the main flash fires,
the same effect as that by the use of radio triggers. This helps create
multiple lighting effects.

Press < S1/S2 > button so that this flash can also function as an optic
S2 secondary flash with optic sensor in M manual flash mode. This
is useful when cameras have pre-flash function. With this function,
the flash will ignore a single “preflash” from the main flash and will
only fire in response to the second, actual flash from the main unit.

With stroboscopic flash, a rapid series of flashes is fired. It can be
used to capture a multiple images of a moving subject in a single
photograph.
You can set the firing frequency (number of flashes per sec.
expressed as Hz), the number of flashes, and the flash output.
Press < MODE > button so 1
that < > is displayed.
During stroboscopic flash, the shutter remains open until the firing
stops. Use the formula below to calculate the shutter speed and set
it with the camera.
Calculating the Shutter Speed
For example, if the number of flashes is 10 and the firing frequency is
5 Hz, the shutter speed should be at least 2 seconds.
Number of Flashes / Flash Frequency = Shutter Speed
To avoid overheating and deteriorating the flash head, do not
use stroboscopic flash more than 10 times in succession.
After 10 times, allow the camera flash to rest for at least 15
minutes. If you try to use the stroboscopic flash more than 10
times in succession, the firing might stop automatically to
protect the flash head. If this happens, allow at least 15
minutes’ rest for the camera flash.
● If the number of flashes is displayed as “--”, the firing will
continue until the shutter closes or the battery is
exhausted. The number of flashes will be limited as shown
by the following table.
● Stroboscopic flash can be used with“ buLb ”.
● Stroboscopic flash is most effective with a highly reflective
subject against a dark background.
● Using a tripod and a remote control is recommended.
● A flash output of 1/1 and 1/2 cannot be set for stroboscopic
flash.
