Power Management
Use ON/OFF Power Switch to power the flash unit on or off. Turn off it will not be used
for an extended period of time. Setting as transmitter flash, it will turn the power off
automatically after a certain period (approx. 90 seconds) od idle use. Pressing the
camera shutter halfway or pressing any flash button will wake up the flash unit. Setting
as a receiver flash, it will enter sleep mode after a certain period (adjustable, 60 minutes
by default) od idle use. Pressing any flash button will wake it up.
Disabling Auto Power Off function is recommended when the flash is used off
camera. (C.Fn-STBY)
Receiver Auto Power Off Timer is set to 60 minutes by default. Another option “30
minutes” is available (C.Fn-RX STBY)
Flash Mode—TTL Autoflash
This flash has three flash modes: E-TTL, Manual (M) and Multi (Stroboscopic). In E-TTL
mode, the camera and the flash will work together to calculate the correct exposure for
the subject and the background. In this mode, multiple TTL function are available: FEC,
HSS, second curtain sync, control with Olympus/Panasonic camera’s menu screen.
* Press <MODE> Mode Selection Button and three flash modes will display on the LCD
panel one by one with each pressing.
ETTL Mode
Press <MODE> Mode Selection Button to enter E-TTL mode. The LCD panel will display.
•Press the camera release button halfway to focus. The aperture and effective
flash range will be displayed in the viewfinder.
•When the shutter button is fully pressed, the flash will fire pre-flash that the
camera will use to calculate exposure and flash output the instant before the
photo is taken.
FEC: Flash Exposure Compensation
With FEC function, this flash can adjust from -3 to +3 in 1/3 stops. It is useful in situations
where minor adjusting of the TTL system is needed based on the environment.

13
Press the <+/-> button.
The flash exposure
compensation amount will
be highlighted on the LCD
panel.
Set the flash exposure
compensation amount.
•Turn the Select Dial
to set the amount.
•“0.3” means 1/3
step, “0.7” means
2/3 step.
•To cancel the flash
exposure
compensation, set
the amount to “+0”.
Press Set Button again to
confirm the setting.
High-Speed Sync
High Speed Sync (FP flash) enables the flash to synchronize with all camera shutter
speeds. This is convenient when you want to use aperture priority for fill-flash portraits.
Setting the flash to High-speed Sync mode when it is on the camera:
Press the <SYNC> button to turn on high-speed sync flash and < > is displayed. Then,
adjust the camera’s shutter to achieve high-speed sync flash.
•With high-speed sync, the faster the shutter speed, the 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, suing high-speed sync flash with Panasonic
camera may occur out of sync.

14
Second-Curtain Sync
With a slow shutter speed, you can create a light train following the subject. The flash
fires right before the shutter closes.
Setting second-curtain sync:
Second-curtain sync function shall be set on the camera’s menu. More details please
refer to camera’s instruction menu.
M: Manual Flash
The flash output is adjustable from 1/1 full power to 1/256th power in 1/10th stop
increments. To obtain a correct flash exposure, use a hand-held flash meter to
determine the required flash output.
Press <MODE> button so
that <M> is displayed.
Press <+/-> to choose
power, then turn the
Select Dial to choose a
desired flash output
amount.
Press Set button again to
confirm the setting.
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.
Optic S2 Secondary Unit Setting
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.
•S1 and S2 optic triggering is only available in M manual

15
Multi: Stroboscopic Flash
With stroboscopic flash, a rapid series of flashes is fired. It can be used to capture
multiple images of a moving subject in 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 <MULTI> is displayed.
Set the flash frequency and flash times.
•Press the Function Button 2 <Times> to select the flash times. Turn the Select Dial
to set the number.
•Press the Function Button 3 <Hz> to select the flash frequency. Turn the Select
Dial to set the number.
•Turn the Select Dial to choose desired flash output. After you finish the setting,
press Set Button and all the settings will be displayed.

16
Calculating the Shutter Sped
During stroboscopic flash, the shutter remains open until the firing stops. Use 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 stroboscopic flash more than 10 times in succession,
the firing might stop automatically to protect the flash head. If this camera 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 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
ah shown by the following table:
Maximum Stroboscopic Flashes
Flash Output / Hz

Wireless Flash Shooting: Radio (2.4G) Transmission
•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 things 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 transmitter unit.
•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 intrucstions.

18
Positioning and Operation Range (Example of wireless flash shooting)
•Autoflash Shooting with One Receiver Unit
•Use the supplied mini stand to position the Receiver unit.
•Before shooting, perform a test flash and test shooting.
•The transmission distance might be shorter depending on the conditions such as
positioning of Receiver units, the surrounding environment and whether
conditions.
Wireless Multiple Flash Shooting
You can divide the Receiver units, into two or three groups and perform TTL autoflash
while changing the flash ratio (factor). In addition, you can set and shoot with a different
flash mode for each firing group, for up to 4 groups.
