2. Multi-flash Lighting Application
Use inbuilt flash or top-mounted flash as master flash.
Place the slave flash light in desired location.
When outdoors, radio signals can be reflected by walls; therefore, place the slave flash
where it has enough space to receive the signal.
Before locating the slave flash light, make a test of whether S1/S2 can work
synchronously (normally).
Do not place any obstacles between the master flash and the slave flash, because they
may block the transmission of radio signals.
In radio flash mode (S1 or S2), if the flash is idle for 30min, it will power off
automatically in order to save power.
The wireless triggering sensor is more sensitive, which makes S1/S2 modes more useful
outdoors. The wireless triggering distance is up to 15m. When it is used outdoors, please
keep in mind the following tips: the wireless triggering window needs to face the master
flash and direct sunlight should be avoided. If following this advice conflicts with your
desired direction of lighting, please try rotating the flash head in each direction to move
the sensor window to meet your shooting needs.
