shorter the effective flash range.
● Multi flash mode cannot be set in high-speed sync mode.
● Over-temperature protection may be activated after 15
consecutive high-speed sync flashes.
● Try not to use high-speed sync flash, for using this
function will reduce flash tube’s service life.
Note: In the wireless remote control mode, using high-speed
sync flash with Panasonic camera may occur out of sync.
High-Speed Sync

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
1that < > is displayed.
Turn the Select Dial to choose
2a desired 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.
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.
● 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.

● You can set up three slave groups for TTL autoflash shooting.
With TTL autoflash, you can easily create various lighting effects.
● Any flash settings for the slave units on the master flash in
TTL/Manual/Multi mode will be automatically sent to the slave
units. So the only thing you need to do is to set the master unit for
each slave group without any operation for the slave units at all
during the shooting.
● This flash can work in TTL /M /Multi / OFF flash modes when set
as a master unit.
As a slave unit, TT685O is compatible with Godox X1 series
transmitter e.g. X1T-C(For Canon), X1T-N(For Nikon), X1T-S(For

and the flash will be fired synchronously with the camera shutter.
- 41 - - 42 -

Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will
bounce off the surface before illuminating the subject. This can soften
shadows behind the subject for a more natural-looking shot. This is
called bounce flash.
To set the bounce direction, hold the flash head and turn it to a
satisfying angle.
360
-7-90
● If the wall or ceiling is too far away, the bounced flash might
be too weak and result in underexposure.
