If there is salt or dirt build-up on the exposed control shaft, clean the
shaft. Open the housing and gently slide the control shaft out of the
control gland. Clean and lightly lubricate the shaft, including the end
of the shaft. Slide the shaft back into the control gland and gently slide
the shaft back and forth a few times without fully removing the shaft
from the gland. Replace the knob noting the flat area on the shaft. The
set screw in the knob should tighten down against the flat area on the
control so the knob does not turn on the shaft. Close housing without
a camera inside and water pressure test in a bathtub or swimming
pool. Rotate* all knobs to make sure the housing is watertight. Check
all controls while the housing is submerged.
*Caution: If your housing has a shutter spring, DO NOT rotate the
shutter control more than 1/16th of a rotation, otherwise, you may
accidentally bend the shutter spring or cause the spring to “pop off”
the control shaft.
Photo Tips
The number one rule in underwater photography is to eliminate as
much water between the camera and subject as possible. Get as
close as you can to the subject, then use the zoom. If you are using
flash for still photos, subjects beyond 6 ft (1.8 m) will not have much
color regardless of strobe power.
