1. Setting flash to AUTO mode

To set the flash to AUTO mode, turn the brightness control counter-clockwise until it stops. It’s okay to rotate the knob beyond the “A” symbol. DO NOT force the brightness control knob beyond its stop point or you may damage the switch. Avoid positioning the knob between the #10 and “Auto” or the flash may not fire.

The above picture shows the brightness control knob in the correct position – all the way counter-clockwise.

2. Power switch easily moves between ON, OFF and TEST – It does not stay locked in position

Some power switches are too loose, causing the switch to move out of the desired position during the dive or when inside the travel case. This can be fixed by loosening the 2 “bridge” screws by ½ turn. If this does not fix the problem, please contact your local authorized SeaLife dealer or the distributor/service center in your country for repair service.

The above picture shows the symptoms of a loose power switch – switch rattles when shaken and easily moves between positions with minimal “clicking” noise.

One of the two screws that secure the switch assembly is shown above. The other screw is located on the other side of the switch assembly. Loosen both screws by ½ turn only.

3. Important – Make sure the cable doesn’t interfere with O-ring when closing the lid

When sealing the Digital Pro Flash, carefully inspect that the black/gray cable does not get trapped under the waterproof door. This will prevent the waterproof door from closing all the way which prevents the o-ring from making a proper waterproof seal.

The above picture shows the cable in a bad position – It will most likely get trapped under the waterproof door.

When closing the waterproof door, gently direct the cable so it does not get trapped or interfere with the sealing area.

If you have any questions or need assistance, please contact your local authorized SeaLife dealer or contact SeaLife Customer Service Center for repair service.

4. Remove, Clean and Install the O-ring & Gasket

Removing the O-ring and Gasket

  1. Grab white cable adapter and pull up to unplug the cable from the flash. Do NOT pull on the wire.
  2. Remove gasket with your fingers.
  3. Remove O-ring with your fingers

Important: Do NOT use tools or sharp objects or you may damage the O-ring or Gasket.

Inspecting and Cleaning the O-ring, Gasket and contact surfaces

  1. Carefully inspect the O-ring and Gasket for cuts(A), tears(B). Replace O-ring and Gasket if damaged.
  2. Carefully inspect O-ring contact surfaces and groove for scratches or other damage. It is normal to see molding “seams” near the hinge and latch area. Contact the SeaLife service center in your country if the contact surfaces or groove are damaged.
  3. Use a moist, clean cotton cloth to remove hair (C), sand (D), and other debris from O-ring, Gasket, O-ring groove and contact surfaces. Never stretch the O-ring or Gasket

Installing the O-ring and Gasket

  1. Install clean O-ring into groove. Be careful not to twist O-ring.
  2. Install clean Gasket, making sure it is completely seated against the waterproof door. The grooved side of the Gasket should sit flat against the waterproof door.
  3. Plug the cable adapter into the flash. Do NOT use force. Check that the white cable adapter is correctly oriented with the plug.


  1. Do not lubricate the O-ring or Gasket.
  2. Do not exceed operating depth of 200ft/60m.
  3. Do not open waterproof door in wet environment. You and the flash must be dry before opening the waterproof door.
  4. Do not expose flash to direct sunlight for prolonged periods of time.
  5. SeaLife recommends replacing the O-ring and Gasket every year.
  6. The O-ring and Gasket set (SL96114) is available at your local authorized SeaLife dealer or online at www.sealifepartsdirect.com

5. Preventing over-exposed (washed out) when Digital Pro Flash is set to AUTO brightness

The flash brightness of the SeaLife Digital Pro (SL961) can be adjusted manually or set to AUTO. Here are a few tips to avoid over-exposed pictures when the brightness control is set to AUTO

1) Make sure AUTO mode switch is set to the #1 position for SeaLife cameras. If the AUTO mode switch is set to 2, 3 or 4 position, you may get over-exposed (washed out) pictures when the brightness control knob is set to AUTO.

2) The SeaLife camera should be set to Ext Flash mode (See camera instruction manual for more details about Ext Flash Mode). When the camera is set to Ext Flash mode, you can push the Flash Button to switch between Macro Flash, Normal Flash and Far Flash. Setting it to “Macro Flash” will darken the image exposure.

3) Use the Digital Pro Flash Diffuser (Item # SL9618 – sold separately) to reduces “hot-spots” and prevent over exposed (washed-out) pictures. This accessory is especially helpful for macro (close-up) pictures. The diffuser easily clips on to the flash and can be flipped up and down.

6. Tips for avoiding rust stains on stainless steel parts

The Digital Pro Flash uses marine grade stainless steel hardware, which is ideal for use in saltwater and marine environment. If not cared for properly, rust stains may appear on surfaces. Make sure to thoroughly rinse off the sealed flash in fresh water after each use. Dry before storage. Rust stains should wipe off with soft plastic bristle brush or clean moist cloth. A great source for more information on stainless steel is http://www.ssina.com.

If the rust stain does not clean off, or if you see that rust stains have entered inside the hinge area, contact your local authorized SeaLife dealer or the distributor/service center in your country for repair service.

7. Flash does not fire

If the flash-ready light is on but the flash will not fire when taking a picture or when switching to TEST, one of the 4 batteries may be dead or defective. Use a volt meter to check the batteries or replace all the batteries with new ones.

If replacing the batteries does not fix the problem, contact your local authorized SeaLife dealer or the distributor/service center in your country for further advice or possible repair service.

8. Flash will not power on

If the flash does not power on (i.e. red ready light does not come on), do this:

  • Make sure batteries are new or fully charged. Try using a different set of new or freshly charged batteries.
  • Clean the battery lid contacts with a fine abrasive emery cloth. Even a thin, near-invisible amount of corrosion can prevent the batteries from making contact.

9. Tips for preventing residual water from entering the flash module when opening the Flash lid:

When you remove the Pro flash from the water or rinse tank, towel-dry the flash and open the waterproof door with the door facing down towards the ground. This will ensure that the residual water that accumulates outside of the O-ring does not enter the flash module.
