Operation
Mode Switch
Turns the power off. Set the
mode switch to [OFF] when
you are not using the strobe.
Set the mode switch to this
position when you shoot with
manual flash using a digital
camera that pre-flashes.
Set the mode switch to this
position when you shoot with manual flash using a
digital camera that does not pre-flashes.
TTL Set the mode switch to this position when you shoot
with DS-TTL flash.
The number of times a digital camera's built-in flash will fire differs
among models. Depending on the number of pre-flashes mode
switch settings can differ, so check settings before shooting by
conducting test flashes.
When 30 minutes has passed from turning on the power, or last
emission of the strobe, the power will turn off automatically (auto
power-off). When turning on the power again, set the mode
switch to [OFF] before setting the desired mode.
CAUTION
Pre-flash
With some types of digital cameras, the light amount is
adjusted with the first flash and the image is taken with the
second flash (main flash). The first flash for adjusting the
light amount is called a pre-flash. With the normal slave
function, the strobe will fire in synchronization with the
pre-flash. As a result, it will recharge during the second flash
(main flash) and be unable to fire.

3
Some housing are not compatible with fiber-optic cable.
When you use this strobe, connect the strobe to the camera
(housing) with a fiber-optic cable (optional). Using a built-in
slave sensor, this strobe is triggered by sensing the light
from a digital camera's built-in flash. If the fiber-optic cable is
not used, depending on the shooting conditions the strobe
may not fire.
Insert the fiber-optic cable's
connector into the fiber-optic
cable socket (slave sensor) of
the strobe until it stops
Connect the fiber-optic cable's
connector to the socket in the
housing
2Secure the fiber-optic cable
with the fiber-optic cable hook
When the housing is not equipped
with the socket, attach the optional
strobe mask to the flash window of
the housing, and then connect the
fiber-optic cable.
The second fiber optic socket on the
right may be used to fire an
additional strobe. Please refer to
page E-10 for details.
Refer to page E-15 when using this
strobe as a sub-strobe.

CAUTION
Refer to the fiber-optic cable instruction manual before use.
When using this model together with the SEA&SEA DX-8000G
/ DX-1G / DX-2G set, (Discontinued products) please attach the
fiber-optic cable adapter (included in the DX-8000G / DX-1G /
DX-2G) to the housing, and then use a fiber-optic cable.
Refer to the housing instruction manual before use.
*1 When the mode switch on both the main strobe and the
sub-strobe is set to [TTL], although it will depend on the shooting
conditions, the sub-strobe may fire at full power. This is caused
by an insufficient amount of light coming from the main strobe,
accompanying the use of flash dimming functionality with the
light-level control dial. In such cases, please set the light-level
control dial on the main strobe to [FULL].
The YS-01 can be used as a sub-strobe if it is connected through
a fiber-optic cable to a main strobe that is connected to a digital
camera. Please set the mode switch on the main strobe and the
sub-strobe each according to the following list.

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 shoo
ting 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.
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.
