5. Use & Care of Housing:

5.1Pre Dive Function Check.

Just before entering the water, make a habit of reviewing that you have carried out the proper steps to close the housing. and the pressure release plug screwed home. Make a

visual check of the O-ring seal. It is also useful to switch on the camera, and check that controls e.g. on/off, zoom, shutter functions operate normally.

Check housing is closed. Close pressure release plug

Check battery and memory card status on the LCD display. Check control knob and zoom function.

If there is a large change of temperature and the housing is not opened for maintenance between dives, it is recommended to equalize the possible pressure difference between the inside of the housing and the ambient by opening the pressure release plug and close it firmly subsequently. Always avoid submerging the housing in hot water for a prolonged time or a cleansing tank where the water may be heated up by the sun.

5.2General Operation.

The control levers and push buttons consist of internal double O-ring seals on a stainless steel shaft. This arrangement is very reliable, however as a precaution, when operating the controls, avoid excessively rapid movements, as this may distort the O-ring. Also please allow for the fact that the camera takes a few seconds to power on. If the camera dose not appear to respond to a control action, make sure that no other controls are pressing on the camera, i.e. locking out further actions. Wear the wrist strap; it is easy to inadvertently let go of the housing, especially if you are distracted.

5.3Cleaning & Storage.

The body & lid of the housing are made of polycarbonate. Polycarbonate was selected for its outstanding strength stiffness, hardness and toughness. As well as its crystal clear transparency and high gloss surface. It has good resistance to weathering, although long term exposure to sunlight should be avoided. Normal operating temperature range is 3°C to 36°C (Storage temperature: -10°C to 50°C) It is good practice to rinse off your housing with fresh water after every dive. Avoid exposure to fine sand. After a series of 10 or more dives, e.g. after a dive holiday, it is recommended to immerse the housing for 2-3 hours in warm water to dissolve any salt deposits that may have built up. No chemical cleaners should be used. Mild detergents e.g. shampoo and soap based cleaners are permitted.

Important !!! Some household chemicals may harm Polycarbonate; the housing should never be exposed to the following classes of chemicals: benzene, toluene, xylene, chlorinated hydrocarbons, methanol, any other solvents, strong acids and bases.

For long term storage please remove the main o-ring from body.

5.4Transportation.

When transporting by air, please ensure the housing is not sealed, to allow the air pressure to equalize. Either remove the O -ring (recommended), or open the pressure release port (a spacer is provided to keep the pressure plug in the open position, please make sure there is no bending of the plug while open). Please protect the housing during transportation. It is recommended to remove the handle, and shutter extension, and wrap the camera in foam or bubble wrap.

D80 specifications

The Nikon D80 is a digital single-lens reflex (DSLR) camera that was launched in 2006, appealing to both photography enthusiasts and semi-professionals with its robust build and advanced features. It was introduced as an upgrade to the popular D70s, incorporating several new technologies that enhanced performance and image quality.

At the heart of the D80 is a 10.2-megapixel CCD sensor, delivering impressive image resolution and detail. This sensor, combined with the EXPEED image processing technology, enables the camera to produce vibrant colors and reduced noise even at higher ISO settings. The D80 offers an ISO range of 100 to 1600, expandable to 3200, accommodating various lighting conditions and allowing for greater flexibility during low-light shooting.

One of the standout features of the D80 is its 2.5-inch LCD screen, which provides a clear and vibrant display for composing shots and reviewing images. The screen also supports Live View functionality, a notable addition that allows users to take photos using the LCD instead of the optical viewfinder, making it easier to capture difficult angles.

The D80 employs an advanced 11-point autofocus system, ensuring precise focusing on subjects. This system includes a center cross-type sensor for improved accuracy, enhancing the camera’s capability in dynamic shooting situations. Furthermore, the D80 offers a compatibility with a wide range of Nikon F-mount lenses, providing photographers with the flexibility to experiment with different focal lengths and effects.

In terms of continuous shooting, the D80 can shoot at a rate of up to 3 frames per second, making it suitable for capturing fast-moving subjects. The camera also includes a built-in flash, which is beneficial for filling in shadows during outdoor photography. For those looking to explore advanced options, the D80 features a variety of exposure modes, including program, aperture priority, shutter priority, and manual modes.

The Nikon D80 operates on a rechargeable lithium-ion battery, providing a significant number of shots per charge, making it a reliable choice for extended shoots. It also supports CompactFlash memory cards, ensuring ample storage for high-resolution images.

Overall, the Nikon D80 stands out with its blend of innovative features, solid performance, and user-friendly design, making it a popular choice among dedicated photographers looking to enhance their craft without venturing into the realm of professional-grade cameras.
