4. Setup

4.1 Camera Preparation

Before placing your Nikon D750 camera into the housing, ensure the camera battery is fully charged and a formatted memory card is inserted. Set your desired camera settings (e.g., white balance, ISO, aperture, shutter speed) as some controls may be less accessible once inside the housing. Remove any neck straps or accessories that might interfere with the housing's closure.

4.2 Housing Preparation

Inspect the housing for any debris, cracks, or damage. Pay close attention to the main O-ring and port O-rings. Ensure they are clean, free of hair or lint, and lightly lubricated with Ikelite silicone grease. A clean O-ring is crucial for a watertight seal.

4.3 Installing the Camera

Carefully slide the Nikon D750 camera into the housing, ensuring it aligns correctly with the internal mounting plate and controls. Gently close the housing, making sure the main O-ring is seated properly and no foreign objects are pinched. Secure the latches firmly.

4.4 Attaching Lens Ports

The 200DL housing utilizes the Dry Lock (DL) port system. Select the appropriate DL port for your lens. Ensure the port O-ring is clean and lubricated. Align the port with the housing's port opening and twist to lock it securely. Verify a tight seal.

4.5 Leak Testing

Before taking the housing underwater with your camera, perform a leak test. Submerge the empty housing in a shallow body of water (e.g., a sink or bucket) for at least 30 minutes. Observe for any bubbles indicating a leak. If bubbles appear, remove the housing, dry it, and re-inspect all O-rings and seals before re-testing.

5. Operating the Housing

5.1 Controls Overview

The Ikelite 200DL housing provides access to essential camera controls through mechanical push-buttons, dials, and levers. These are designed for comfortable and intuitive operation, even when wearing gloves. Familiarize yourself with the location and function of each control before diving.

5.2 Depth Rating

The Ikelite 200DL Underwater Housing is rated for a maximum operating depth of 200 feet (60.96 meters). Always adhere to this limit to ensure the safety of your camera and the integrity of the housing.

6. Maintenance

6.1 Post-Dive Care

Immediately after each dive, rinse the housing thoroughly with fresh water, especially if used in salt water. Operate all controls while rinsing to flush out any trapped salt or debris. Allow the housing to air dry completely before opening.

6.2 O-Ring Care

Periodically remove, clean, and inspect all O-rings. Look for nicks, cuts, or signs of wear. Replace damaged O-rings immediately. Apply a thin, even coat of Ikelite silicone grease to the O-rings before reinstallation. Store O-rings in a cool, dry place away from direct sunlight.

6.3 Storage

When not in use, store the housing in a cool, dry place away from direct sunlight. It is recommended to store the housing with the latches open and the O-rings removed or slightly unseated to prevent compression set.

7. Troubleshooting

This section addresses common issues you might encounter with your Ikelite 200DL Underwater Housing.

• Leakage: If water enters the housing, immediately remove the camera and dry both the camera and housing. Inspect all O-rings for damage, dirt, or improper seating. Re-lubricate and re-test.
• Controls Sticking: Rinse controls thoroughly after each dive. If a control remains stiff, it may require cleaning and lubrication of the shaft seal. Consult Ikelite support if the issue persists.
• Condensation Inside Housing: This can occur due to temperature differences. Ensure the camera and housing are at the same temperature before sealing. Using desiccant packets inside the housing can help absorb moisture.
• Difficulty Closing Latches: Ensure the main O-ring is properly seated and not twisted. Check for any obstructions preventing the housing halves from mating correctly.
