Mounting The Camera - Nikon D90 User Manual

7. Mounting the camera

Prepare yourself at ease and try to avoid stress!
Obligations when using underwater housings for cameras:
Mount zoom (or focus) control gear (if applicable). Slide the zoom gear

over the objective. Position the gear so that the gearwheel of the zoom
control gear matches the gearwheel of the zoom control inside the
housing.
Remove the protection cap from the objective (if a port is mounted).

Turn the ON/OFF switch onto position OFF (camera and housing).

Turn the tripod screw completely towards the back. Gently slide the
camera onto the camera support until it reclines. The objective should
be centered in the port mounting. If the zoom control gear does not func-
tion properly slightly turn it until the teeth fit. Never use force while
mounting the camera. Be sure the flash connection is free and not
jammed.
Next, fix the tripod screw handfirm. Check whether the camera is

mounted in a stable way without tension.
Slide the flash adapter onto the flash connection of the camera (red

connector facing back of camera).
Turn on the camera.
Check whether all control switches can be operated and function over

the complete range. If not, this has to be checked and fixed before
continuing.
Set the parameters of the camera as much as possible according to the

settings which will be used under water.
If applicable, connect the external flash and test the camera and flash.

If function fails, check the connections for their position and clean
them.
Closing of the housing:
Check the main o-ring and the opposite sealing surface for dirt. If

necessary, clean with a wet cloth. After appr. 5 dives, remove the main
o-ring with a clean cloth by pressing it out of his groove. Clean the
o-ring, the groove and the sealing surface.
