19 C300 MKII Setup Page 19 Mount lens. Mount the lens you plan to use at this time. Mount the lens to the C300 MKII camera.

20 C300 MKII Setup Page 20 Lens Gear Drives (LGD s) General Notes. This section addresses the installation of three LGD s 1 x CCW (Counter Clock Wise) and 2 x CW (Clock Wise). These designators are applied because two LGD s point in a CCW direction and the other in a CW direction, The LGD s are marked CCW and CW. C300 MKII includes three LGD s 1x CCW and 2x CW. You will install guide bars and drive shafts that match the lens of your choice. Visit GatesHousings.com or contact Gates for a current cross reference. Secure Guide Bars. Insert the guide bars by threading them into the front bulkhead. Tighten firmly by hand no tools are required but wrench flats are provided on the guide bars should this be necessary. Install Drive Shafts. These are ¼ black delrin and have a flat spot milled into one end. This end inserts into the drive coupler at the face of the front bulkhead. Secure gently with the set screw on the coupler. Do not overtighten. Insert the drive shaft into the coupler. One end of the shaft will have a small flat spot. Align this with the set screw, and tighten gently. Do not overtighten. Note: Different Gates housing shown. Thread the Guide Bar into the front shell and tighten by hand. LGD s mounting. Install the LGD s in their proper orientation with pivot gear screws facing forward. Slide it onto the guide bar and drive shaft, then line up the LGD with the lens gear you wish it to access.

21 C300 MKII Setup Page 21 The sequence of tightening screws on the LGD s is important. Step 1. Tighten the LGD mount screw securing it to the guide bar. Critical: the drive shaft/gear hub must be centered with the opening on the bracket. Center the drive shaft/gear hub to the bracket. Tighten the screw and secure the LGD to the guide bar. Step 2. Pivot the larger gear onto the lens gear such that it makes intimate contact. Carefully observe that the gear is still properly aligned and the drive shaft/gear hub is centered with the LGD bracket (see photo). Tighten the two pivot screws gently to secure it in position. With the drive shaft/hub centered, pivot the larger gear to make intimate contact with the lens gear. Gently tighten 2 pivot screws. Step 3. Firmly tighten the screw that couples the drive gear hub to the drive shaft. Couple to Drive Shaft. TIP. The gear hub / drive shaft coupling acts like a clutch the drive shaft will slip when reaching the end of travel in either direction. Tightening the screw more will allow less slip. Adjust this amount of slip at your discretion. Set the focus/iris indicators. The left and right side Gear Controls have indicator rings. These shipped in the parts kit. These are white plastic for marking focus / iris indications.

22 C300 MKII Setup Page 22 Secure the ring with the two set screws in the knob as shown. Verify Operation. Once positioned and secured check operation of the Focus and Iris controls. They should rotate freely but with slight resistance in both directions and through the entire range of travel. If not, repeat steps 1-3. In a subsequent section Check Operation you will power on the camera and verify the Zoom control is also smooth and operational. Slip the white ring over the Gear Control knob. Secure with set screws here and opposite on the knob.

23 C300 MKII Setup Page 23 Video Connections (Optional) If you have the HD-SDI option installed, no special camera setup is required. You need only connect the HD-SDI surface feed cable to the bulkhead connector as shown in the photo. HD-SDI Surface Feed cable (optional) Note:: Different housing shown Water Alarm (Optional) If you have the optional water alarm installed there are three alarm conditions to know: Condition LED Siren New Battery (Insertion) Bright Intense blink while siren plays Ascending tones played 4 times Water Intrusion Bright Intense Blink Grating Warble sound. Alarm will sound for duration of detection. Low Battery Low Intensity fast blink Descending tones played 8 times pausing approx. 20 seconds between plays after alarm test or water detection.

24 C300 MKII Setup Page 24 The alarm can be tested anytime by shorting the detection contacts that lead to the water alarm transducer. The water detection condition will activate for 6 seconds. If the battery is drained the low battery condition will sound. The water alarm requires a single 6V battery like Radio Shack model or A544. Your battery should be removed when stored (e.g. between dive trips). Check the battery prior to every die to ensure proper operation. Change when indicated. CAUTION: You must wait a minimum of 30 seconds between battery insertions to allow the unit to fully discharge. Water Alarm siren and battery installed into the Rear Shell

25 C300 MKII Setup Page 25 Front Bulkhead, Port and Port Ring Inspection. Before installing the Port Base, Port Ring and Port, visually inspect the o-rings for dirt or other foreign matter that may compromise the seals. Do the same with the Front Shell face (where the Front Bulkhead mates) and Port bore where the o-rings seal. See the separate document Housing Care and Maintenance Guide for more details. NOTE: Some lenses do not require a Port Ring. Refer to Gates Lens Compatibility Matrix for details. CAUTION: Do Not lubricate the ORANGE Front Bulkhead o-ring. It is silicone material and lubricant may cause damage. Only the BLACK and YELLOW o-rings are safe to lubricate. Install the Port Base. Position the Port Base over the entire lens / LGD s and secure to the front bulkhead with 4 screws. Tighten the 4 screws firmly. Install Front Bulkhead with 4 screws and washers. Tighten firmly.

26 C300 MKII Setup Page 26 Lubrication. Lubricate the yellow Port o-ring with silicone grease. Also liberally lubricate the Port bore. This will greatly aid installation of the Port. TIP: Liberal lubrication of the Port and Port Ring o-ring allows easy rotation during installation/removal. Install the Port Ring (if needed). The Port Ring will mate with the Front Bulkhead and then rotate 90 degrees CW to its normal position where it will stop. Carefully mate the Port Ring to the Front Bulkhead, and assure alignment when fully seating the Port Ring. 2 1 Mate the Port Ring then rotate 90 CW until it stops.

27 C300 MKII Setup Page 27 Install the Port. Similarly, the Port will mate with the Port Ring and then rotate 90 degrees to its normal position where it will stop. Carefully mate the Port to the Port Ring (or Front Bulkhead), and assure alignment when fully seating the Port Ring. Verify seals. Inspect the Front Bulkhead, Port Extender and Port are fully seated with no gaps. 2 Mate the Port then rotate 90 CW until it stops. 1

28 C300 MKII Setup Page 28 Secure External Monitor to Housing. As shown in the image below, the External Monitor will secure to the top of the Port Base. Slide the monitor onto the camera housing dovetail and tighten with thumbscrews.

29 C300 MKII Setup Page 29 Seal Check Seal Check Manual. Follow the procedures in the Seal Check manual for verifying integrity of the housing. NOTE. Ensure the fitting plug is installed prior to submersion! Failure to do so will result in a wet camera. Seal Check Fitting on rear left of housing. Final Checks Visual Inspection. Look closely at all seal mates Port, Port Ring, Front Bulkhead and main Housing seal for gaps. Look over the housing one final time. Verify operation. As a final check, power on the camera and verify all controls are functioning normally. If you have the optional HD-SDI surface feed cable, ensure an image is present at the surface end.

37 C300 MKII Operation Page 37 Port Options At this time of publication Gates SP80 Dome, FP80 Flat Port, and SP10 Dom Port are options are available for C300 MKII. When choosing a Port consider the following tradeoffs and limitations. Dome Port Optical material: Optical-grade Acrylic or anti-reflective coated glass. Purpose: Wide to super wide imaging. Advantages: Retains FOV. Corrects for field of view distortions inherent in Flat Ports. Wide FOV capable. Up to 180 degree fisheye are possible depending on the camera lens capability. Disadvantages: Little or no zoom. Domes inherently limit zoom through and varies with camera lens employed. Flat Port Optical material: Optical grade acrylic or AR coated glass. Purpose: Medium to macro imaging. Advantages: Zoom through. Flat Ports retains the zoom capability of a lens. Macro. Flat Ports are excellent for macro shots and the use of close up diopters to capture small subjects. Disadvantages: No wide shots. By their nature, Flat Ports do not allow wide shots. Loss of FOV. Like a SCUBA mask, Flat Ports decrease FOV by 25%. NOTE: The optical interaction between any given lens and a Dome or Flat Port is unpredictable. Distortions and aberrations can occur with either Port. As such, Gates does not warrant optical performance or image quality. Gates endeavors to collect data from the field and our own testing as a resource to customers, but you should always characterize your lens of choice for use underwater.

38 C300 MKII Operation Page 38 Tripod Mount (Optional) An optional Tripod Mount (for use with third party tripods) can be secured to the base of the shell. The Tripod Mount has additional ¼-20 threaded holes for mounting other items as you need. Tripod Mount (Optional)

39 C300 MKII Operation Page 39 Tripod Legs (Optional) Tripod Legs are optionally available to mount directly to the C300 MKII housing. Rear Tripod Leg is installed as shown on a bracket with two bolts to the housing. Front Tripod Legs are secured to the front foot as shown. First install the ball mount and secure very tightly with a wrench to prevent accidental unthreading. Then attach the Tripod Leg and clamp. The front Tripod legs are mounted here, on the leading section of the foot. Thread the ball mount into the foot and screw very tightly with a wrench. This leg is shown collapsed and tucked when not in use. The rear Tripod leg is mounted as shown to the rear shell with a bracket and 2x bolts + 2x #10 washers per bolt. The right and rear Tripod legs are shown ready for use. The legs are extensible from 7 to 18 inches.

40 C300 MKII Operation Page 40 Lighting Systems C300 MKII has provisions to utilize a variety of lighting systems. Ball mounts for the light arms may be located in several locations on C300 MKII: a) threaded into the top of the Handle Grips: b) on the Foot Rails; or c) onto accessory mounts that slide onto the same dovetail slots as the handle grips. Controlling Reflections While it is unlikely, you may encounter reflections from within the port area of C300 MKII from anything shiny. To control such reflections Gates recommends two easy measures: Blackening the shiny area with a black permanent marker; or Install a mask over the lens, as shown in the photo. This measure is rarely needed, but if necessary black neoprene makes an excellent, flexible masking material. Cut to your specific lens and cut the outer ring diameter to fit the port. Port Masks will help control reflections. Note: Different Housing shown.

41 C300 MKII Operation Page 41 Travel / Transport C300 MKII requires several preparations for travel. No Camera. DO NOT transport your EOS-C300 MKII camera inside the housing. Severe damage may result. No Trim Weights. DO NOT transport the C300 MKII housing with trim weights installed. Severe damage may result. Secure Camera Mount. The Camera Mount must be well secured. Use the tools provided to tighten two thumbscrews firmly. Protect connectors. Cover any housing-to-camera connectors to protect them from damage during transit. Packing.
