Power Management
Use Power Switch to power the flash unit on (Long press the button for one
second) or off. Turn off if it will not be used for an extended period of
time. Setting as a master flash, it will turn the power off automatically
after a certain period (approx. 90 seconds) of idle use. Pressing the camera
shutter halfway or pressing any flash button will wake up the flash unit.
Setting as a slave flash, it will enter sleep mode after a certain period
(adjustable, 60 minutes by default) of idle use. Pressing any flash button
will wake it up.
C.Fn Disabling Auto Power Off function is recommended when the flash is
used off camera.
Flash Mode TTL Autoflash
This flash has three flash modes: TTL, Manual (M), and Multi (Stroboscopic).
In 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 functions are available: FEC, HSS, second curtain sync, etc.
*** Press < MODE>** Mode Selection Button and three flash modes will
display on the LCD panel one by one with each pressing.
TTL Mode
Press Mode Selection Button to enter TTL mode. The LCD panel will
display .
- Press the camera release button halfway to focus.
- When the shutter button is fully pressed, the flash will fire a pre-flash that the camera will use to calculate exposure and flash output the instant before the photo is taken.
Display”HI”: When the flash output value is up to the maximum value, “HI”will
be displayed and blinking for 3 seconds. Adjust the camera’s parameters if
underexposure appears.
Display”Lo”: When the flash output value is up to the minimum value, “Lo”will
be displayed and blinking for 3 seconds. Adjust the camera’s parameters if
overexposure appears.
FEC: Flash Exposure Compensation
With FEC function, this flash can adjust from -3 to +3 in 1/3rd stops. It is
useful in situations where minor adjusting of the TTL system is needed based
on the environment. Setting FEC:
- Press the SET Button and the flash exposure compensation amount will be highlighted on the LCD panel.
- 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 s../ to confirm the setting.
High-Speed Sync
High Speed Sync (Hss 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.
Press the button to turn on high-speed sync flash and < a5″. 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 to avoid using high-speed sync flash, which will cut short flash tube’s lifetime. Note: With the Panasonic cameras in wireless control mode, the High-Speed Sync may not sync fire.
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 the Second-Curtain Sync function on the camera menu, please read camera instruction manual.
M Manual Flash
The flash output is adjustable from 1/1 full power to 1/128th power in 1/3rd
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.
-
Turn the Select Dial to choose a desired flash output amount. In co high-speed sync mode, the adjustable flash range is 1/16-1/1.
Flash Output Range
The following table makes it easier to see how the stop changes in terms of
f/stop when you increase or decrease the flash output. For example, when you
decrease the flash output to 1/2, 1/2-0.3, or 1/2-0.7, and then increase the
flash output to more than 1/2, 1/2+0.3, 1/2+0.7, and 1/1 will be displayed.

Optical S1 Secondary Unit Setting
In M manual flash mode, press the 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.
Optical S2 Secondary Unit Setting
Press the 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 and off camera high-speed mode are only available
in M manual flash mode.
Multi Stroboscopic Flash
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 button so that is displayed.
-
Turn the Select Dial to choose a desired flash output.
-
Set the flash frequency and flash times.
- Press the SET Button to select the flash frequency. Turn the Select Dial to set the number.
- Press the SET Button again to select the flash times. Turn the Select Dial to set the number.
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.
- 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.
Maximum Stroboscopic Flashes:
Flash Hz output| 1| 2| 3| 4| 5|
6-7| 8-9| 10| 20-50| 60-99
---|---|---|---|---|---|---|---|---|---|---
1/4| 6| 3| 2| 2| 2| 2| 2| 2| 2| 2

Wireless Flash Shooting: Radio (2.4G) Transmission
- 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 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 IM /Multi / OFF flash modes when set as a master unit.
When using Godox 2.4G wireless X system, TT3500 is perfectly compatible with
other products of our company.
As a master unit, TT3500 can control the following slave unit models:
AD600, AD600M, AD3601I-C, AD36011-N, AD200, V8501I, Tt600.
As a slave unit, TT3500 can be controlled by the following master unit
models: X1T-O, V8501I, Tt600.
Note: with the TTL functions need the latest firmware version (please
update after 2017-7-1).
- Even with multiple slave units, the master unit can control all of them via wireless.
- In this user manual, “master unit” refers to the camera flash on a camera and “slave unit” will be controlled by the master unit.
