To alter the focus of the Super SeaSpy, carefully open the unit following
the instructions detailed in Section 5.2, “Dis-assembly and Re-assembly
procedures”.
By rotating the nuts on either side of the camera module (see Section 6.1,
“General layout”)the mounting collar will be compressed or released, affecting
the focus of the unit accordingly.
4.2.2. Dynamic Light Control (DLC)
Upon initial power up the Super Seaspy camera will start up in Dynamic Light
Control (DLC)mode. This means that the ring LED’s will react automatically
to any changes in the reflectivity of the work surface or scenery ambient light
conditions: - In darker areas the ring LED’s will brighten and the reverse in
lighter areas.
Manual control mode of the ring LED’s can be obtained by applying an
analogue voltage to the +/- LIGHT line (PIN1 on Tritech connector). See
Section 6.3, “Electronic light control” for details on the nature of the voltage
signal to be sent.
If you wish to return to DLC mode, after making a manual control input, the
camera must be switched OFF for several seconds. Upon switching ON again
the camera will revert to DLC mode.
4.2.3. Water Corrected Lens
The Super SeaSpy is fitted with an "Ivanoff Corrected" lens system which
effectively compensates for the different refractive index of water vs that of
air. This means that the picture quality is optimised through the reduction of
radial distortion and chromatic aberration.
