Synchronization of light emission and shutter release
The light activate in sync with the strobe light input to the
optical communication receiver of the light module.To ensure
that the light is synchronized with the camera shutter release,
it is recommended to use the following strobe setting on the
camera.
1. Use a mode with pre-flash capability.
2. If the system is capable of RC lighting, you can reduce
battery consumption by using RC emission only.
CAUTION : If the strobe is set to the manual lighting
mode, pre-flash may not be available and
it will not be possible to synchronize light
module activation with the shutter release.
Notes on light intensity selection
Light intensity in the Flash Mode can be selected from three
levels (the default is High). When using an SLR camera,
exposure can be adjusted by setting the exposure to the
manual mode and adjusting the iris aperture (f-number).
When using a camera that does not have manual exposure
adjustment capability such as a compact camera, exposure
can be adjusted by using the exposure correction function in
the Auto mode. However, with certain shooting distances such
as macro shooting, the correction may be insufficient, in which
case overexposure may result.If this happens, set the light
module’s light intensity to Mid or Low.
[ Relationship between light intensity in Flash Mode and
light intensity in Light Mode ]

High Max. level of non-step brightness control
Mid
2nd level of 4-step brightness control
Low
Min. level of non-step brightness control
Notes on lighting duration selection
The flash lighting duration of the light module can be selected
from two settings (the default is 0.3 sec.). If you are using the
camera in the sequential shooting mode, setting the lighting
duration to 1 sec. makes possible sequential shooting for about
1 second.
