Light & Motion D100 manual Pre-Dive Checklist, ROC and Focus Controls

Pre-Dive Checklist

1.Install media card into camera.We recommend at least a 1GB card.

2.Install a fully charged EN-EL3 battery with battery board into the camera.

3.Verify operation of all controls and gears.

4.Turn on the strobes and take a test picture.

5.Check the housing lens and/or conversion ring for proper seal(s).

6.Check that the rear plate o-rings are seated correctly and that the rear latches are in the closed and locked position.

ROC and Focus Controls

ROC - Defined

ROC is an innovative strobe and camera control interface built into the Titan Housing. ROC allows the underwater photographer to obtain up to 12 manual power levels on most TTL compatible strobes. ROC’s strobe power control spans from full power to -7 f/stops or ROC can disable the strobes from firing. This gives the digital underwater photographer unprecedented flexibility and convenience when lighting subjects. Up to two strobes can be connected to the Titan via Nikonos style or Wetlink style bulkheads. ROC allows the power levels for each strobe to be controlled independently or together.

In addition to the unique strobe control, the Titan D100 handles also offers electronic Auto-Focus,Auto Focus Lock, Area Focus Selection, and control of Command Dials.

ROC - Status

ROC is ON when the power level LEDs are displayed.

ROC is in STAND-BY after being idle for 60 seconds and power level LEDs are not dis- played. ROC is ready to take a photograph, this is just a power saving mode.To check the power level of the strobes when ROC is in Stand-By mode, press any of the strobe but- tons on either handle. This will not alter the ROC power settings, but will return ROC to an ON status.

ROC is powered by the camera’s battery.When the camera is off, ROC is off.

Programming ROC

ROC can only function successfully by knowing the type of strobe(s) being used. It is necessary to program ROC prior to using the Titan underwater. Once ROC is programmed it will never have to be reprogrammed unless a different model strobe is used. ROC will retain its programming even when the ROC is in the off status.

ROC’s default strobe profile is for Sea & Sea YS-90DX/90/60/50. If you are using different strobe(s) use the following procedure to change the ROC strobe profile.

1.	Press and hold the ~ + and ~ - buttons on the left or right handle (Fig. 35) until the
	REC LEDs begin to pulse.When the LEDs are pulsating, ROC is in programming mode.
2.	Press the ~	+ or ~ - buttons on the ROC handles (Fig. 36) to position the LEDs in
	the appropriate LED setting for your strobes. Refer the chart in Fig. 38 to determine
	which LED setting is for which strobe.
	Use the L ~	R Strobe button to select and program both strobes simultaneously or to

program the left and right strobes independently (Fig 37). If both LED are moving, both strobes are being programmed. If only one LED is moving, only one strobe is being programmed. The Left and right LED banks program the left and right strobes respectively.

3.When the LEDs are positioned in the appropriate setting, press the and hold +/- buttons on either handle to save the strobe profile (Fig 39). LEDs will then be a steady light indicating current strobe power.

During the programming process, if programming is idle for 60 seconds ROC will record the strobe profile of the current LED position and enter stand-by mode.

ROC Stand-by and Time Out schedule

ROC is fully active when the LEDs are showing strobe power levels.

After 60 seconds of inactivity ROC enters stand-by mode. ROC is still active but turns off the LEDs to conserve battery power. ROC will return to the active mode by pressing any button from either ROC handle or the mechanical shutter.
