Diffuser and Deflector cont.  
A diffuser and deflector are  
included with the housing. The  
diffuser is white transparent  
plastic. The deflector is also  
white but is not transparent  
and has a decal on the front.  
Lens Port  
Diffuser/Deflector material  
Treat the glass in the lens port as a camera lens. After use, rinse  
and gently dry the lens port to avoid water spotting. To clean  
use a mild soap solution or lens cleaner.  
Do not use alcohol or window cleaner on the Lens Port.  
The Lens Port will accept (2) Wide-Angle Adapters. The Wide-  
Angle Adapter #9306.80 which is required to mount the Inon  
UWL-150AD Bayonet style wide-angle lens. The Wide-Angle  
Adapter #9306.81is required to mount the #6420 Ikelite W-20  
Wide-Angle Lens and other manufacturers (67mm) screw  
thread style wide-angle lenses.  
These lenses can be secured onto the Wide-Angle Adapter  
above or below water as they are designed to have water  
between the front of the port and the accessory lens. Make sure  
no air bubbles are trapped between the port and the accessory  
lens. Any vignetting that occurs can be eliminated by zooming  
the camera lens slightly. The camera’s built-in flash cannot be  
used with wide angle  
lenses. The front of the  
lenses are so large they  
block the camera’s flash.  
To properly light subjects  
when using a wide angle  
lens an external strobe  
should be used. Due to  
the wide-angle of  
coverage of these lenses,  
the DS125 Substrobe is  
recommended or two  
DS51Substrobes.  
Port Clamp  
Spring  
To install the diffuser or  
deflector spread the port clamp  
at the spring end and slide over  
the lens port. The white plastic  
should be placed in front of the  
camera flash. The port clamp  
should be pushed back against  
the front of the housing.  
Spread to Install  
Diffuser  
The diffuser should be installed when using the camera’s built in  
flash. When shooting with the camera’s built-in flash at  
approximately 2 feet (0.6 m) or less, the lens port on the  
housing may block a portion of the light from the camera’s  
built-in flash, creating a shadow in the lower left of the photo.  
If this occurs, zoom the lens slightly to eliminate the shadow.  
(You can test this above water)  
Wide-Angle Adapter  
wide-angle lens  
Deflector  
The deflector should be installed when using an external strobe  
such as the DS51or DS125 Substrobe and EV Controller. The  
deflector will redirect the camera’s flash to the EV Controller  
which controls the external strobes output.

Maintenance  
Substrobe  
DS125  
The Ikelite Digital 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 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 of  
the housing clean.  
6. Rinse the housing exterior thoroughly in fresh water after each  
salt water use. Dry with a soft cloth. Dry lens port to eliminate  
water spotting.

After several uses in salt water soak the housing exterior in a  
mild soap solution, rinse and dry before storage. When storing  
the housing, remove the back o’ring, lightly lubricate and place  
in a plastic bag. Place the plastic bag with o’ring inside the  
housing for safe keeping.

Control Maintenance  
Control Maintenance Cont.  
3. Some of the controls have a short shaft and cannot be pulled  
out exposing the shaft for lubrication. In the unlikely event one  
of these controls sticks or becomes difficult to operate you can  
remove the control from the housing and lubricate it, or return  
the housing to Ikelite for maintenance. To remove the control,  
loosen the set screw in the knob (allen wrench required);  
remove the knob. 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 it back and  
forth a few times without fully removing the shaft from the  
gland. Replace the knob, NOTE 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.  
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.

General Tips  
Photo Tips  
1. Due to the power required to operate the camera, flash, and  
LCD screen it is a good idea to start each dive with a fresh set of  
batteries.  
1. The number one rule in underwater photography is eliminate as  
much water between camera and subject as possible. Get as  
close as you can to the subject, then use the zoom. If you are  
using flash, subjects beyond 6 feet (1.8m)will not have much  
color.  
2. Some cameras reset their flash to AUTO when the camera is  
turned on. If you prefer another setting be sure to select it.  
3. As soon as you enter the water, take a moment and check the  
housing to see that it is properly sealed.  
4. Next, check to see if there are any bubbles on the face of the  
lens port. If there are, take your finger and remove them. If  
there are bubbles on the lens port they can produce soft focus  
spots in your photographs.  
2. The camera’s built-in flash is very close to the camera lens. The  
flash can light up any suspended particles in the water and they  
can be recorded in your picture. This effect is called backscatter.  
To eliminate as much backscatter as possible, photograph close.  
Photograph in clear water; do not stir up the sand or silty  
bottom. If backscatter becomes a problem in the environment  
you are photographing, an external flash will help eliminate  
much of the backscatter.  
3. Digital cameras have a slight lag time between when you press  
the shutter release button and the camera actually takes the  
picture. Hold the camera steady a second or two after pressing  
the shutter release button.  
4. Do not shoot down on subjects as they will quite often blend  
into the background and be difficult to see in the photograph.  
Shoot subjects straight on or shoot up at a slight angle using  
the blue water as a contrasting background.  
5. Underwater flash is used to restore the warmer colors filtered  
out by the water as well as to illuminate the subject. When  
photographing underwater, set the camera to use flash on  
every shot. If the camera’s flash is set to AUTO and the sun is  
behind your subject, the camera may see enough light that it  
does not fire the flash. With the sun behind the subject the  
subject is shaded (dark) and needs flash for a good exposure.  
NOTE  
5. If you are shooting with the camera’s built-in flash and the  
cameras lens set to widest angle you may need to zoom the lens  
slightly or a shadow may appear in the lower left corner of  
close-up photographs. The lens port may block some of the  
light. (You can test this above water)  
To shoot photographs closer than 2 feet (0.6m), you need to  
use an external strobe such as the DS51or DS125. With an  
external strobe you can position it so nothing blocks the light  
path between the strobe and the subject.

6. When using daylight or flash if your camera consistently over  
or underexposes the image you may want to adjust your  
camera’s exposure compensation settings. Many cameras allow  
you to adjust both available light and flash exposure with an EV  
control in the camera’s menu.  
All Ikelite products are warranted against any manufacturing  
defects for a period of one (1) year from the date of purchase.  
Defective products should be returned prepaid to Ikelite. Ikelite  
will, at its discretion, repair or replace such products, and will  
return to customer prepaid. All other claims, of any nature,  
including but not limited to bulb failure are not covered. Except as  
mentioned above, no other warranty expressed or implied, applies  
to this Ikelite product.  
7. Many photographers transfer their images to the computer  
where they can fine tune the appearance of the image. Many of  
the image manipulation programs make you think you can  
magically correct any image taken and make a good picture.  
One thing to remember when using image manipulation  
programs, if the image is overexposed much of the color is  
missing. If the color is missing you cannot adjust it. If images  
are slightly underexposed the color is there, it is just dark and  
you can adjust it to some degree. So if you error in exposure it  
is better to have the image slightly underexposed than over  
exposed.
