Quantity	Part Number	Part Description
1	VR-PRO4-13-0001-N	Camera Assembly Front with Port Ring (Pro 4) (NTSC)
1	OR-154	O-Ring #154

Steps

1. Place your index and middle fingers under the inside top of the front hull ring assembly and your thumb against the pressure sensor nut, and gently pull the hull ring assembly from the main hull. If the hull ring assembly binds while pulling the top, you may need to pull the bottom to even it up for easier removal. Do NOT pull it out too fast, or you could damage the camera ribbon cable.

2. Disconnect the camera ribbon cable from the rear of the camera by pulling the cable from the clip and then the connector.

3. If you plan to replace the O-ring, remove it by pinching it around the front hull ring to create a slack section that can be grabbed. Do NOT use a metal tool to remove the O-ring.

Front Hull Ring Assembly with Camera Replacement Procedures

Time required for this step: Approximately 5 Minutes

Tools required for this step:

• O-Ring Lubricator

Parts involved in this step:

VR-PRO4-13-0001-N Front Hull Ring Assembly with Camera

Quantity	Part Number	Part Description
1	VR-PRO4-13-0001-N	Camera Assembly Front with Port Ring (Pro 4) (NTSC)
1	OR-154	O-Ring #154

Steps

1. Use a new lubricated O-ring, or remove and lubricate the existing O-ring, and install it in the larger diameter O-ring groove of the front hull ring.

2. Orient the front hull ring so that the receiver bracket is facing toward the ROV and at the bottom of the main hull.

3. Thread the camera ribbon cable through the clip on the camera interface. The cable should be inserted so that the free end is pointed towards the rear of the camera and can be easily installed in the connector

4. Insert the camera ribbon cable connector into the socket on the camera interface making sure the contacts are on the same side.

5. Position the front hull ring at the front of the main hull and make sure the camera ribbon cable is routed so that it will not interfere with camera tilt movements.

6. Make sure the camera axis is level with the ROV from side to side.

7. If the ROV board set is in the ROV, make sure the front of the heat sink engages in the receiver bracket at the bottom of the front hull ring.

8. Being careful not to pinch the o-ring, press the front hull ring into the main hull until is seats against the main hull. Make sure that you press the front ring evenly so that it does not bind.

Tip

Before proceeding to the next step, connect the ROV to the control panel and test the camera tilt and focus functions to make sure the camera tilts and focuses smoothly through the entire tilt and focus range.
