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-16S
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 Φ3.5mm plug. Insert a trigger plug here
and the flash will be fired synchronously with the camera shutter.
