Closing the Housing  
1. Place housing face down in your  
lap.  
2. Check to see that there is an o'ring  
on the housing back and that it is  
clean and in its proper location.  
3. Guide the back onto the housing.  
The o'ring should touch the  
housing all the way around. There  
should be an even gap all the way  
around between the housing and  
the housing back.  
4. Lift the lid snaps so they are  
extended and place the lid snap  
into the hook on the housing back.  
5. To close the housing push  
down on the lid snaps until  
they snap into place . Lid  
snaps on opposite sides of the  
housing should be closed at the  
same time. Be sure they are down  
far enough to engage the lock.  
Double check - Once the housing is  
closed, check the o'ring seal. Check the gap between the  
housing back and the housing, it should be even all the way  
around.  
Look through the clear plastic back at the o'ring. You should see a  
darkened area where the o'ring is compressed against the  
housing back. If you do not see an even black compression seal  
all the way around the back, open the lid snaps, reseat the  
housing back and close the lid snaps. Visually check the seal again.

Installing the Zoom Clamp & Gear Sleeve On the Type 1 Lenses  
Installing the Zoom Clamp  
The Zoom Clamp has springs so it can be expanded to fit over  
the Zoom ring of the lens as shown in (Fig. Q. Install the Zoom  
Clamp with the extension tabs toward the rear element of the  
lens. After installing the Zoom Clamp, check that when rotating  
the Zoom Clamp it rotates the Zoom ring on the lens. If the  
Zoom Clamp is not tight enough to rotate the Zoom ring on the  
lens, remove the Zoom Clamp and install the rubber strips  
(supplied) to the inside of the Zoom Clamp as shown (Fig. F).  
Two thicknesses of rubber strips are provided. Start by installing  
the thinnest rubber strips, if the Zoom Clamp still is not tight  
enough use the thicker rubber strips. Reinstall the Zoom Clamp.

Installing the Port  
There are two port locks on  
the front of the housing.  
(See housing front) Each  
port lock has a Release  
Button, lift the release  
button and slide each Port  
Lock away from the port  
opening. In the unlocked  
position the Release Button  
will remain in the up  
position as shown.  
To prepare the port for installation, remove the port o'ring and  
lightly lubricate it. The port seal is a side-to-side seal and  
requires the o'ring to be lightly lubricated for easy installation.  
Put a small amount of lubricant on your fingers and draw the  
o'ring through your fingers to lightly lubricate it. Do not stretch  
the o'ring. Check that the lip of the port where the o'ring fits  
and the sealing surface on the housing are clean. Place the port,  
with o'ring into the housing's port opening. Press down on the  
port firmly and evenly until you feel the port slide into place.  
Continue to push down on the port and push each port lock  
forward until it clicks into place. It may help to slightly rotate  
the port as you push in on the port lock. When the port lock  
clicks into place the Release Button will drop down against the  
port lock.  
Check around the perimeter of the port seal to see that the  
o'ring is properly sealed and not extruded.

Lubricants  
1. Ikelite provides silicone lubricant with the housing. We  
recommend that you use only Ikelite lubricant as some other  
brands may cause the o'ring to swell and not seal properly.  
2. Use only enough lubricant to lightly cover control shafts and  
o'rings. Wipe off any excess lubricant with a clean cloth.  
Lubricant is not a sealant, it is used to reduce friction. Excessive  
lubricant can collect sand and dirt which may interfere with  
proper sealing.  
CAUTION  
Never use spray lubricants as the propellant ingredient can  
cause the plastic housing to crack.

Strobe Arms  
This housing offers two types of arm mounting systems. The  
top of the rubber handles utilize Ikelite's Quick-Release Arm,  
available with the SA-100R Arm system.  
The bottom of the rubber handles have a wing nut that accepts  
the Ikelite Tray Mount. The Tray Mount comes with the Ikelite  
SA-125 Arm system and the SA-100T Arm system.  
Pre-Dive Your System  
It is recommended that you take the complete system into a  
swimming pool before use in open water. This will give you a  
chance to become familiar with the handling and operation of  
your housing and strobe(s).

Optional Accessories  
Lead Weight #0906.58  
The buoyancy of the system will depend on the size and  
number of strobes used as well as the weight of the camera.  
Ideally the system should be slightly negative in the  
environment in which it will be used. If you need to add weight  
to the system, an optional lead weight is available. To add the  
lead weight remove the (2) screws from the bottom of the  
aluminum tray. Place the lead weight into the pocket of the  
aluminum tray and reattach.  
#5512.68 includes:  
Ikelite Lube — Port O'ring — Housing Back O'ring  
While both the Port and Back o'rings should last quite some time  
it is best to carry a spare in case one becomes damaged or lost.  
Storing the Housing  
When the housing is going to be stored for a prolonged period it  
should be soaked in a mild soap solution, rinsed and dried  
thoroughly. Remove the back and port from the housing.  
Remove the back and port o'rings, lightly lubricate them and  
place them in a plastic zip-lock bag. Place the plastic bag inside  
the housing for storage. Operate the push buttons periodically.

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. D o 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 Ikelite 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.  
CAUTIO N: Never use spray lubricants as the propellant  
ingredient can cause the plastic housing to crack.

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.  
24  
Download from Www.Somanuals.com. All Manuals Search And Download.  
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 (alien 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.

General Tips  
1. You should completely assemble and test your set-up in a  
swimming pool before using it in open water.  
2. It is a good idea to start each photo dive with a fully charged  
battery(s) in the camera and strobes.  
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  
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.  
5. Set Image Resolution to the Highest JPG format available or  
RAW. Higher resolution settings are required for printing. High  
resolution images can easily be reduced in size with software  
and retain their original quality. A Low resolution image can be  
enlarged with software but much of the quality will be lost.  
6. Digital images are usually transferred to the computer where  
their appearance can be fine tuned. Many of the image  
manipulation programs make you think you can magically  
correct any image taken and make a good picture. One thing to  
be aware of is that if an image is overexposed that some of the  
color information in the file is missing. If the color is missing  
you cannot adjust it. If images are underexposed the color and  
detail may be 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 overexposed.

Photo Tips  
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. Digital cameras have a slight lag time between when you press  
the shutter release button and the camera actually takes the  
picture. It only takes a slight amount of pressure to trip the  
shutter, if the shutter doesn't trip immediately don't push down  
harder on the shutter control as you may damage the camera.  
Hold the camera steady a second or two after pressing the  
shutter release button.  
3. 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.  
4. Underwater flash is used to restore the warmer colors filtered  
out by the water as well as to illuminate the subject.  
5. For balanced lighting meter the background and set the camera  
aperture accordingly. Use TTL, adjust the strobe's power  
settings, or move the strobe closer or farther away to properly  
expose the subject with the chosen camera aperture.
