Press < MENU > button to enter C.FN-SLAVE to choose S2 function, so that this flash can also function as an
optical S2 secondary flash with optical 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.
Optical S1 Secondary Unit Setting
In M manual flash mode, press <MENU> button to enter C.FN-SLAVE to choose S1 function, so that this flash can
function as an optical 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.
Optical S2 Secondary Unit Setting
● S1 and S2 optical triggering is only available in M manual flash mode.

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 that
1<MULTI> is displayed.
Calculating the Shutter Speed
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.
Number of Flashes / Flash Frequency = 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.
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.
● 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.
● Stroboscopic flash can be used with“buLb”.
● 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.

1. Over-Heat Protection
●To avoid overheating and deteriorating the flash head, do not fire more than 100 continuous flashes in fast
succession at 1/1 full power. After 100 continuous flashes, allow a rest time of at least 10 minutes.
●If you fire more than 100 continuous flashes and then fire more flashes in short intervals, the inner over-
heat protection function may be activated and make the recycling time over 10 seconds. If this occurs, allow a
rest time of about 10 minutes, and the flash unit will then return to normal.
