To check the mode switch
You can check whether the settings of the mode switch are
correct, by shooting the strobe with a digital camera. The number
of times a digital camera's built-in flash will fire differs depending
on the shooting mode. If you change the shooting mode of the
camera, check the setting of the mode switch again for that
mode.
Set the camera's built-in flash
to the forced-flash mode, and
mount the camera to the
housing. Then, connect the
housing and this product
together with a fiber-optic cable.
Set the mode switch to [ ]
and the light level control dial
to [FULL], point the digital
camera at the front of the
strobe and shoot an image.
The built-in flash of the camera
must flash.
Release the red-eye-reduction
function.
3Check the image captured by
the camera
If you see a white flash in the strobe
or an image that is completely
white, then the strobe has fired
and the setting is correct.
If the image shows a dark reflection from the strobe, that
means that it is not synchronized and the strobe didn't fire.
Change the mode switch to [ ], try taking another picture,
and then check the new picture.

DS-TTL photography
The DS-TTL system on this strobe is a slave TTL system with
flash dimming functionality. This system is useful for when
you are using another main strobe that can pre-flash such as
a camera's built-in TTL flash or another TTL strobe that is
connected to the camera.
Set the mode switch to [TTL], and set the light level
control dial to [FULL]
Take a photography
3Adjust the light level with the light level control dial to
decrease the amount of light for exposure if you get
an overexposed image
DS-TTL mode is activated only when you are using a camera's
built-in flash or other TTL strobe connected to the camera. Use
this storbe as a sub-strobe of the main strobe. DS-TTL can not
be used if the main strobe (camera's built-in flash) is not equipped
with the TTL function, or if the main strobe (camera's built-in
flash) dose not pre-flash.
When you shoot, set the built-in flash of the camera to the
forced-flash mode. The strobe will not fire unless the built-in
flash of the camera fires.
You cannot increase the light amount with the light level control
dial higher than that the camera has detected.
