6. Wireless Flash Range
After the master and slave units have been set, position them within the
wireless flash range shown below.
• Use the mini stand (provided) for the slave unit(s). The mini stand also has a tripod socket.
• Use the bounce feature to turn the body of the slave unit so that the sensor is exposed to the
master unit.
• For an indoor setup, the positioning can be less precise since the wireless signals can bounce off
the walls.
• After positioning the master and slave unit(s), fire a test flash to make sure the wireless flash
system works.
• Do not place any objects between the master unit and slave unit(s) which may obstruct the
wireless transmission.
Set the master unit’s flash mode to
M.
Set the camera as desired for flash
photography.
