ONLY UPON REQUEST it is possible to use external flash with OPTICAL TRIGGER SYSTEM.
USING THE FLASH WITH OPTICAL TRIGGER SYSTEM (OPTIONAL)
Manual Trigger for automatic Flash control (optional)
The TTL flash trigger is designed to trigger
external flash. It operates via the cameras hot-
shoe. The battery should last for approx. 60.000
flash triggers.
1.
To use the
Trigger Flash Switch [ON]
.
If you always use optical fiber it is possible
to leave the trigger on
[ON]
mode without
consuming the battery: it will work only when
the hotshoe is connected to the camera and
the camera is in position inside the housing.
The LED light will flash green for a few
seconds indicating that the battery is fully
charged only when the camera is inside
attached via the hotshoe and the flash
is correctly working. Otherwise the LED
will flash red indicating that the battery is
almost empty.
2.
Slide the flash trigger hotshoe connector into camera’s hot-shoe until it cannot
go in any further. Make sure the hotshoe wire is directioned correctly. Remember
to insert the camera inside the housing at this point, if you did not do it before.
3.
Switch on the camera and test the flash trigger by pressing the shutter release
button of the housing: the LEDs in the front should flash instantaneously. You
can see this through the optical bulkheads.
4.
To detach, reverse the above steps.
5.
To make sure that the trigger works in
TTL
press the
[INFO]
button on the camera
and check that “TTL” appears on the left side of the monitor.
OFF ON
N.B. If you normally use the optical fiber cable we recommend to keep the trigger
always in the [ON] position. This avoids the necessity to switch on the trigger once in
water (the trigger does not consume the strobe battery) .
