Here are some common causes and solutions if the Sea Dragon flash is not firing with the DC2000:
If this information does not fix the issue, please contact your local authorized SeaLife dealer or the distributor/service center in your country for further advice or possible repair service.
If the Sea Dragon flash fires sometimes but not all the time, or fires on land and not underwater, check the following common causes:
Cable end must aim towards flash. Sometimes the cable is pulled back slightly and aiming towards the inner wall of the Flash Link adapter, which will cause firing issues.
Connecting Flash to Olympus, Sea&Sea and other underwater housings using a 7mm optical flash port

Above right: Completely sealed
On the flash end of the cable, remove the locking screw and make sure there is no debris trapped inside the opening hole of the flash head. Clean out with a cotton swab if necessary. Then, insert the cable completely into the locking screw so a little bit sticks out the other end (See picture). Now, attach locking screw to flash head and tug on cable to make sure it’s secure.
The Sea Dragon Flash SL963 is compatible with single-use alkaline and lithium AA batteries or rechargeable NiMH AA batteries only. Do not use Nickle-Zinc (NiZn) or 14500 rechargeable lithium batteries as those batteries have higher voltage output that will damage the electronic circuitry.

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.
