with the camera built-in flash as long as the strobe and the camera are positioned on the same axis and as
long as there is not much ambient light available. However, if the strobe slave sensor isn't pointed directly
at the internal camera flash, or when photographing during daylight, in clear water and bright conditions,
the slave sensor might fail recognizing the output of the internal camera flash. Connecting a fiber optic
cable between the internal camera flash and the slave strobe ensures full synchronization in all angles and
diving conditions.
Attaching Fiber Optic Cables to the Housing
1. When installed on the housing, the fiber optic cable plate and the two adaptors inserted inside it
allow for an easy attachment of up to 2 fiber optic cables to the housing.
2. If the fiber optic cable you have features a different type of adaptor, remove this adaptor from the
end of the cable and use the adaptors included with the FRX100 IV Housing instead.
3. Remove the Fiber Optic Cable Plate from the
housing. Insert your fingers beneath the adaptors
installed inside the plate and push the plate
upwards till it is removed from its slot.
4. Prior to installing the fiber optic cable on the Fiber
Optic Cable Plate, make sure that the two black
adaptors are firmly and properly installed inside the
plate (image #19).
5. Insert the exposed end of the fiber optic cable into
the small hole of the adaptor unit, starting from the end that features a screw and pushing it
towards the end that features an O-ring (image #20), until the fiber optic cable reaches the end of
the adaptor, which can be verified by looking from the other side of the Fiber Optic Cable Plate. The
fiber optic cable should be extending out no more than 1mm (image #21).
