Connecting the Strobe
When you use this strobe with a compact digital camera,
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 either not fire, or not obtain
TTL flash exposure compensation.
CAUTION
Some housings are not compatible with fiber-optic cable.
1Insert the fiber-optic cable's
connector into the slave sensor
socket of the strobe until it stops
2Connect the other end of the
fiber-optic cable's connector to
the socket in the housing

TTL Photography
Photography based on the camera's photometric data of the
subject's brightness, which is used to regulate the light amount
of the strobe so that the correct exposure is achieved.
Even if the distance from the subject has changed, the light
amount will be controlled automatically and you can easily
obtain the correct exposure. After shooting with TTL automatic
light control, the TTL lamp on the light level switch will illuminate
in green for approximately 3 seconds. When automatic light
control was not used, the TTL lamp will not illuminate.

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. When the mode switch is set to
[M] and the light level switch is set to [FULL], 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.

CAUTION
FULL：●For a compact digital camera that does not pre-
flash, or acamera that has apre-flash cancel
function.
Refer to the digital camera instruction manual for
details.
●If your camera pre-flashes, set the light level switch
to [1/2].
●The light amount (Guide Number) of the main flash
of this strobe will differ depending on the number
of pre-flashes.

●Always remove batteries from the product after use.
●After using the product, maintain the O-rings before storing.
Examine the O-rings before and after each dive. We recommend
early exchange of the O-rings, at least once a year.
●Every two years we recommend a complete overhaul of O-rings
regardless of the frequency in use, for the best performance of
the product.
●If you do not use the product for an extended period of time, periodic
maintenance will keep internal electronic parts from deterioration.
Once a month, install batteries and fire a test flash. While the
