Sea Dragon Flash Tips and Technical Updates

1. Flash-ready light keeps blinking
2. Flash fires when pushing test button but not with camera
3. Preventing over-exposed (washed out) when using AUTO brightness
4. Connecting Sea Dragon Flash to Olympus [mirrorless] camera housings

1. Flash-ready light keeps blinking

It’s normal for the blue flash-ready light to blink for a few seconds after powering on the flash or taking a picture. A blinking light means the flash is charging. A steady light means the flash is ready to fire again. If the ready light is blinking for more than 10 seconds, replace or recharge the batteries. Make sure all 4 batteries are okay – the flash won’t charge if 1 of 4 batteries is bad. Never mix and match batteries.

If the ready light keeps blinking with new batteries, contact your local authorized SeaLife dealer or the distributor/service center in your country for further advice or possible repair service.

2. Flash fires when pushing test button but not with camera

1) Make sure flash is synchronized to your camera. Do this:
a) Turn OFF flash power.
b) Push and HOLD test button, and power ON flash.
c) The flash-ready light will be blinking.
d) With your camera connected to the optical cable and flash, take a test picture. Important: Make sure your camera's flash is set to FORCE ON so it always fires.
e) The flash-ready light will stop blinking. The flash is now synchronized to your camera.

2) Make sure optical cable is properly connected to the camera and flash. Refer to page 8 of the Sea Dragon Flash instruction manual. Manual is available online at sealife-cameras.com/manuals

3. Preventing over-exposed (washed out) when using AUTO brightness

1) If the Auto brightness setting consistently over-exposes the picture, the “average” brightness can be reduced. Do this:
a) Turn flash power on
b) Set brightness dial to #1 (dot between 2 and "A")
c) Push and hold the TEST button down for 4 seconds.
d) The flash-ready light will blink a few times indicating the new Auto bright setting is saved in memory.
Note: If pictures are consistently under-exposed (darker), repeat the above with the brightness dial set to #10. The Auto bright setting can be adjusted to any level between 1 and 10, with 10 being the highest average brightness. The factory setting is 5.

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) Make sure the white diffuser is installed. The diffuser reduces “hot-spots” and prevent over-exposed (washed-out) pictures.

4. Connecting Sea Dragon Flash to Olympus [mirrorless] camera housings

All the Olympus mirrorless camera housings include a rubber optical cable holder plugs. The plug can be used to block the inner’s camera flash or as an optical cable holder for connecting to the Sea Dragon flash.
