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.

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.

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.

The
TT685IIO
attach to the camera is called the transmitter
unit, and a TT685IIO that is wirelessly controlled is called the
receiver unit.
●
You can also wirelessly control the
TT685IIO
set as the receiver
unit with the transmitter X1T-C (sold separately). For details on
setting the transmitter unit functions, see the transmitter’s
instructions.

You can set up five receiver groups for TTL autoflash shooting.With
TTL autoflash, you can easily create various lighting effects.
●
Any flash settings for the receiver units on the transmitter flash in
TTL/Manual/Multi mode will be automatically sent to the receiver
units. So the only thing you need to do is to set the transmitter unit for
each receiver group without any operation for the receiver units at all
during the shooting.
●
This flash can work in TTL /M /Multi / OFF flash modes when set
as a transmitter unit.
