Ports Continued

FLAT PORT

For standard, macro, and telephoto lenses.

Due to refraction flat ports reduce the angle-of -coverage of a lens and at the same time enlarge the image. This makes the flat port ideal when using standard, macro or zoom lenses to shoot small subjects. Note that if a port is long enough to accommodate the full length of a 1:1 macro lens, the lens may vignette when used at infinity. If access to the lens' full range is desired, then select a dome port instead.

Maintenance

The Ikelite Housing should be given the same care and attention as your other photographic equipment. In addition to normal maintenance we recommend that the housing be returned to Ikelite periodically to be checked and pressure tested.

1. Do Not leave the camera and housing in direct sunlight for prolonged periods. Heat may damage the camera.

2. Do Not ship the camera in the housing.

3. Before using the housing, always check the tightness of the set screw in each control knob.

Check each control gland penetrating the housing to make sure they are tight. There is a slight chance that either could vibrate loose during travel.

4. Keep the back and port o’ring clean and lightly lubricated. To lubricate remove the o’ring from the back. Put a small amount of lkelite lubricant on your fingers. Draw the o’ring through your fingers to apply a light coating of lubricant. Only apply enough lubricant to make the o’ring feel slick. Do Not stretch the o’ring. This light coating of lubricant will help to keep the o’ring from drying out and will help to show a dark sealing line when the housing back is properly sealed.

5. Keep the area where the o’ring fits and the sealing surface clean. 6. Rinse the housing exterior thoroughly in fresh water after each salt water use. Depress push buttons several times during rinse.

Dry with a soft cloth. Dry port to eliminate water spotting. After several uses in salt water soak the housing in a mild soap solution, rinse and dry.

CAUTION: Never use spray lubricants as the propellant ingredient can cause the plastic housing to crack.

(*) Zoom lenses that do not focus to 12” require a +4 diopter close-up lens be added to the lens when used underwater behind a dome port.

(1) Port shade may have to be removed to avoid vignetting.

(2) Lens requires special zoom clamps and focus sleeve #5509.28.

(3) Lens diameter does not allow zoom operation in the housing.

(4) Auto or Manual focus must be selected before closing the housing. Requires special zoom clamp and focus sleeve #5509.28 for manual focus.

Control Maintenance

Ikelite controls are designed to provide years of reliable service with minimal maintenance.

1. Push button controls require no maintenance other than rinsing in fresh water after saltwater use. If a push button control becomes difficult to push or if it sticks when depressed, soak the housing in luke warm fresh water. After a few minutes operate the push button. If this does not correct the problem, return the housing to Ikelite for maintenance.

2. Some of the controls have long shafts. These controls can be

pulled out, exposing the shaft (see drawing).

To lubricate the control, gently pull on the knob until the stainless steel shaft is exposed. Lightly lubricate the shaft, then move the shaft in and out several times. This will lubricate the x’ring in the Ikelite control gland. This should be done before using the housing after a prolonged storage period, or once a week when the housing is in use.
