1. A water-tight test without the camera inside the housing is highly recommended
when using the system for the rst time and after the changing of port and O-Ring(s).
2. O-rings should be kept clean and lubricated at all times. Discontinue use immediately
should you notice any leakage. Do not use lubricants from other brands with the
silicone rubber O-ring on this housing, only use the lubricant provided by ISOTTA.
After checking the O-ring to make sure that there are no scratches, dust, or debris,
apply a light coating of silicone grease to the entire O-ring with your nger.
Applying too much grease will make it easier for dust and debris to adhere to the
O-ring, and could cause ooding.
3. When tting the O-ring into the O-ring groove, insert it straight into the groove; do not
bend or twist it.
4. Store the housing in a robust, shock-proof container during transportation; avoid
transporting with any equipment, such as a camera, inside the housing, to avoid breakages.
5. When travelling by air, please remove the port from the housing as this may lead to damages.
6. Do not open the housing in a sandy environment. Protect the interior from moisture and
debris in order to prevent malfunction or leakage.
7. Do not store the housing in an environment of high humidity.
8. Do not leave the housing and the camera in direct sunlight for prolonged periods.
9.
Do not store the housing in high temperature environment as in the car cockpit under the sun.
10. Keep out of reach of children, failure to do so could result in injury.
11. Always dry the front port, the lens, the ash window or the nder using a soft cloth
to prevent stain or salt residue from marring the glass surface. Do not use solvent or
alcohol to clean the port, viewnder or LCD window.
12. When not in use the case for long time O-rings should be removed and stored sepa-
rately. Replace the O-rings once a year for a secure watertight.
Use only Isotta O-rings.

waterproofed before rinsing. After each dive it is recommended to remove the port
from the housing in order to avoid the possibility that the port gets stuck. Storage of
the housing is possible only after cleaning and drying its surface.
14. Unauthorized disassembling and/or modication could result in malfunction or
ooding, and void product warranty. Take the product to a ISOTTA authorized reseller

It is possible to replace the port in the open air after the removal of possible water
drops on the surface of the housing.
You can also mount different brands ports on request via adapter rings. When using
the adaptor rings the safety lock function is lost.
NOTE:at rst usage there may be resistance when turning the port. Make sure O-rings
are well lubricated. Double O-rings might generate resistance. If you cannot turn the
port, check that both O-rings are inserted and in place and that the port is attached

N.B. The portholes must be replaced in the open air.
Do not leave the porthole mounted for a long period of time. Use preferably Isotta ports
for maximum performance of the housing. Do not use solvents on the port.
To clean them you should use a microber cloth. If necessary, you can use mild soap
only on the external side.

USING THE FLASH
You can use the external ashes with the following modalities:
With OPTICAL FIBER
Two ber optic connectors are present on the housing top with standard “Sea & Sea”
tting. In this case you have to use the bushings for optical ber placed on the top.
Pass the optical ber cable of the ash in the specic space on the bushing.
With Optical Fiber you have to use pull up ash of the camera.
Manual TRIGGER Flash control
The ash operates via the cameras hot-shoe. The battery should last for approx.
60.000 ash triggers.
1. Switch from the [OFF] (A) position to the [ON] (B) position.
At this stage the Trigger and the Moisture Sensor are not yet on / working.
2. Insert the camera on the tray.
Slide the camera directly into the internal part of the housing until the end.
Move the safety slider to the right to lock the machine on the plate.
3. Insert the Hot Shoe on the camera to allow the Trigger to work (C).
The LED will start to ash. The following situations may occur:
• green light ( ) signal, 8 ashes: charged battery, trigger is working;
• red light ( ) signal, 8 ashes: low battery, reduced autonomy;
• red light ( ) signal, 3 ashes: battery completely unloaded and to be
replaced.
4. Switch on the camera and Test the ash by pressing the shutter release button
of the housing: the LEDs in the front should ash instantaneously.
You can see this through the optical bulkheads.
5. To detach, reverse the above steps.
CAUTION: if you insert the Hot Shoe while the camera is ouside the housing,
the trigger and the humidity sensor will not work (D).
Please NOTE: if the housing is not used for a long time or during the set up of the
camera, it is advisable to keep the Trigger on the [OFF] position.

19
N.B. If you normally use the optical ber cable we recommend to keep the trigger
always in the [ON] position. This avoids the necessity to switch on the trigger once in
water (the trigger does not consume his battery).

TROUBLESHOOTING
• BUTTONS DO NOT WORK
Check the correct positioning of the camera;
• BUTTONS GET STUCK
Apply lubricant to the button. Press the button several times to distribute the lubricant.
N.B.* Don’t use vaseline grease on the O-ring seals.
We recommend the use of original ISOTTA products.
• THE FLASH DO NOT SHOOT IN SYNCRO MODE
Make sure you have inserted the hotshoe contact all the way down and check that
you entered correctly the ash contact.
• TRACES OF SALT ON JOINTS WHILE ASSEMBLY HOUSING
Salty water on the joints: rinse well and wipe the points with Vaseline oil, except for
the optics, which should be cleaned only with special detergents.
• RED LED IS ON
A red LED and acoustic signal on the back of the housing indicates excessive moisture
inside the housing. If this happens underwater, you should get out of water as soon as
possible in respect of security measures and ensure that there were no leaks.
Re-clean and re-install the back and port O-rings. Take the housing underwater
without a camera installed to ensure that the leaking has been corrected.
