1. Make sure you have inserted the hotshoe into the appropriate space and the camera into the housing. The trigger will not work if the hotshoe and the camera are not correctly inserted.
2. Make sure the hotshoe is inserted in the correct direction. To insert it, follow the direction of the arrow. The cable must remain towards the rear monitor.
3. If the trigger has stopped working, replace the battery and make sure the "+" symbol is facing outwards.

FIBER OPTIC FLASHES DO NOT FIRE:

FLASHES FIRE EVEN WITH THE TRIGGER OFF:

The trigger only controls the firing of fiber optic flashes. If you use flashes with a synchro mount, turn off the flash directly so that it does not fire.

1. Make sure the inside of the housing is completely dry, especially the humidity sensor cable ends. To find the cable ends, simply follow the gray cable inside the housing to the bottom.
2. If everything is dry, make sure the humidity sensor cable ends are not touching each other.

1. Make sure your camera is turned on.
2. Make sure you have removed the porthole cap.
3. Make sure you have removed the lens cap before closing the case.
4. Make sure you have not activated LiveView.

First of all, check that the porthole lock is not engaged.

When the case is left inactive for a long time, it is possible that the O-rings dry out and create traction, making it difficult to open the porthole.

Always remember to lubricate the O-rings before installing the porthole.

To remove the macro porthole and the extension rings, try our special keys B102 or B120.

Alternatively, place the case in a stable position, where it cannot fall and turn the porthole anti-clockwise with both hands.

If your lens is vignetting or distorting the image, check the port chart for your lens and make sure you are using the correct port combination.

1. Rinse the hermetically sealed housing under fresh running water, making sure to press all buttons.
2. Spray neutral silicone spray on the stuck buttons while pressing them.

Remember to rinse the hermetically sealed housing under fresh running water, making sure to press all buttons, after each dive. This prevents the buttons from becoming stuck due to salt water.

Make sure you have removed the strap clips, close the housing and operate the buttons.

The buttons do not work properly if the housing is open.

Replace the O-rings whenever they appear cracked, crushed, or cut.

If the housing will be stored for an extended period of time, remove the O-rings from their seats and replace them before using it again.

We recommend sending the housing to Isotecnic or an authorized center every two years or every 500 dives, to ensure optimal functioning of the housing.
