Godox QT400IIM Flash Head - Manual (Page 9)

Memory Function
The device is equipped with memory function for the panel setting. It will help remember the panel setting 3 second
after you set it. When starting up the flash next time, the panel setting will be the same as the status before
powering it off.
Tube Replacement
Shut down the power and remove the power cord before replacing the flash tube and wear insulated gloves. Then,
loosen the iron wire on the tube, keep a balanced hold on the two feet of the flash tube and pull out the old tube
gently. Take down the feet casing from the old tube and put it on the new one. Hold two feet of the new tube, and
target directly towards the two copper outlets, then push them slightly in. Twine the iron wire on the stainless steel
sheet to fix the flash tube.

Other Applications
Wireless Control Function
The flash unit is built in with a Wireless Control Port so that you can wirelessly adjust the power level
of the flash and the flash triggering.
To control the flash wirelessly, you need a FT-16 remote control set (on-camera and on-flash). Insert
its receive end into the Wireless Control Port on the flash and insert the transmit end into the camera
hot shoe. Settings made on the hotshoe-mounted transmit and receive ends will be
wirelessly communicated to the flash. Then you can press the camera shutter
release button to trigger the flash. You can also hold the transmit end at
hand to control your off-camera flash.
For full instructions on the use of FT series remote control, see its
user manual.
Sync Triggering
The Sync Cord Jack is a Φ6.35mm plug. Insert a trigger plug here and the flash will be fired synchronously with the
camera shutter.
