Godox TT600 in Slave Mode
Set the TT600 to Radio Slave Mode
First, we’re going to set the flash, making sure that it’s ready to receive orders.
Set to Radio Slave
If you turn the TT600 on, you will see that it’s in Manual mode and ready to work on-camera. Follow the next steps to set it on Radio Slave mode.

Press and hold the MODE button until you see the antenna icon blinking.

Rotate the wheel until you see the “S” icon.

Press the SET button.
The Flash is now in Radio Slave mode.
Set the Channel
The next step is to set the channel you previously chose for the flash and transmitter to communicate. Follow the next steps to do it:

Press and hold the Gr/CH button until the channel number is blinking on the screen.

Rotate the wheel until you see the channel number you’re going to use.

Press the SET button.
As you can see in the image, I set my flash to listen to orders on channel 9.
Set the ID
The TT600 flash doesn’t have the ID feature so, if your setup includes TT600 hotshoe flashes, make sure to turn ID off in the transmitter and the rest of the flashes.
Assign Flash To a Group

You can assign the flash to a group by pressing the Gr/CH button repeatedly, until you see the group you want on the screen. You’ll see groups A through E.
Set Flash Zoom
You can’t set the TT600 zoom from the transmitter, you can only set the flash zoom manually, by following the next steps:

Press the ZOOM/Fn button.

Rotate the wheel to change zoom values.

Press the SET button.
I set my flash zoom to 35mm, as you can see in the image.
The flash is now ready to receive orders on channel 9 and ID is not available in this flash model. It will respond to orders directed towards group B. These orders should include the flash mode and power setting. Let’s set the transmitter!
