I. Safety Warnings  
Make sure you follow these important safety warnings to avoid the risk  
of fire or injury.  
Avoid using the light above water for prolonged periods of time. The  
light is designed for underwater use and water is needed to displace  
heat. The metal light head at full power will reach temperature of about  
140F (60C) degrees within a few minutes, which may cause burning if  
touched. A thermal sensor will automatically dim the light if internal  
temperatures reaches 150F (65C) degrees. Immediately turn off light if  
any parts of the light become hot to the touch.  
If water has entered the light, immediately turn off power and follow  
these instructions: Remove and dry the battery. DO NOT use the battery  
once it has become wet. Wet batteries must be replaced. Allow battery to  
dry and dispose it in accordance with local battery recycling regulations.  
The battery chamber is waterproof. If no water has entered the LED light  
head, the chamber may be cleaned without causing permanent damage  
to the electronics. Rinse the waterproof battery compartment with fresh  
water and allow the inside to dry. Replace the o-rings and apply lube.  
Install new, fully-charged battery and test light. If light does not operate  
properly, please contact your local SeaLife dealer or the SeaLife service  
center in your country.  
Do not use battery if the outer casing is cracked, separated, damaged  
or has become wet. Dispose battery in accordance with local battery  
recycling regulations.

I. Safety Warnings  
Never expose battery to fire or intense heat. Do not expose light to  
direct sunlight for prolonged periods of time.  
Removebatteriesfromlightbeforetransporting,travelingorlongperiods  
of storage. Remember to use the protective battery cover included when  
the battery is not inside the light or charging tray to prevent accidental  
short-circuiting the battery contacts.  
Airlines impose strict safety regulations for handling and shipping  
lithium ion batteries. Spare lithium batteries may not be packed in your  
checked baggage but may be packed in your carry-on baggage. It is  
important to pack spare batteries in such a way as to prevent metal  
objects from touching the contacts and potentially short-circuiting the  
battery. Always use protective battery cover included when the battery is  
not inside the light or charging tray to prevent accidental short-circuiting  
the battery contacts.  
Only use the specified battery and battery charger approved by SeaLife.  
Using any other battery or charger may cause fire, injury and permanently  
damage the light.  
Observe all SCUBA dive safety rules and control your buoyancy at all  
times. Consult your dive instructor for dive safety questions.

VII. Maintaining a waterproof seal (Before your dive)  
1) The light uses two O-rings to maintain a waterproof seal.  
2) Every time you open the battery cap make sure the O-rings and  
sealing surfaces are clean, undamaged and lubricated.  
3) Dampen a clean cotton cloth and wipe it around the o-ring and  
o-ring contact surfaces to remove any hair, sand or debris.  
4) Carefully inspect the o-ring for cuts, tears or other damage.  
Replace o-rings if damaged.  
5) Lube O-rings regularly. Apply a small amount of silicone lube  
on your finger tip and wipe it around the O-rings. Wipe off  
excess lubricant. The o-ring surface should have shiny, wet  
appearance.

XIII.Great pictures made easy  
There are plenty of challenges that photographers face in the  
underwater world. Please take some time to review SeaLifes  
online guide called Great Pictures Made Easy by visiting www.  
sealife-cameras.com. The guide is located under the Technical  
Support menu. The following information summarizes the basic  
principles of underwater photography.  
Crystal clear water  
Clear water is essential  
for good underwater  
pictures. Low visibility,  
caused by fine particles  
suspended in the water,  
will diminish the picture  
and video quality. As a  
general rule, limit your  
shooting distance to 1/10  
of the water visibility. For  
example, if the visibility is  
20 ft, limit your shooting  
distance to 2 ft. Try to  
keep the light as far away from the camera lens as possible to  
minimize backscatter.  
19  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Limit your shooting distance  
Water is 800 times denser than air and quickly absorbs light. The  
Sea Dragon lights have an effective range of about 3ft (90cm) to  
4ft (120cm) depending on visibility and ambient light conditions.  
Closer shooting distances result in better pictures and video.  
20  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Control your buoyancy  
Get your buoyancy under  
control and set yourself up  
in the ideal position before  
taking a picture or shooting  
video. This allows you to hold  
the camera steady and control  
your shooting distance. Good  
buoyancy control will help  
you avoid stirring up the sandy  
bottom which will cloud-up the water and cause backscatter.  
Controlling your buoyancy is very important for your diving safety  
so don’t start shooting until your buoyancy is under control.  
Practice makes perfect  
There is no better way to learn  
than from your mistakes.  
Become familiar with your  
camera controls so you can  
make  
quick  
adjustments  
depending on the conditions.  
Take the time to practice and  
experiment with different  
settings. Review your pictures  
and learn from your mistakes.  
21  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Compose a good picture  
Avoid shooting down on the subject from above. Shooting down  
usually results in a poor contrast because the subject blends into  
the background. Try and shoot upwards from below the subject  
so you get a blue water background and better contrast. Get the  
entire subject into your picture frame. Don’t cutoff the hands, fins  
or head of your subject. You can always crop you image later on  
your computer if you want.  
Video tips  
Hold the camera as steady as possible and move (pan) very slowly.  
A jumpy, fast-moving video is hard for anyone to watch and can  
actually cause motion sickness.  
Avoid shooting video clips more than 1 minute. It is difficult to edit  
a lengthy video clips because the large file size. You can always  
patch together short video scene into a longer movie using video  
editing software, like Microsoft Movie Maker or Mac iMovie.  
Always observe dive safety rules and Never Touch Marine Life  
Do not let photography distract you from diving safely. Observe  
marinelife-Nevertouchmarinelife.Beawareofyoursurroundings  
to avoid contacting anything. Keep your dive gear close to your  
body.

XIV. Advanced Settings  
Auto Flash Detect  
(Only applies to Sea Dragon 2000F SL984 light)  
The Sea Dragon 2000F light (SL984) includes a flash sensor that  
will turn off the light for 2 seconds if it detects an external flash  
firing. This feature helps reduce backscatter. You may disable the  
auto flash detect as follows:  
1) With light in the OFF state, push and hold the power button  
for 3 seconds.  
2) Release the power button when the indicator lights begin  
blinking and light turns off.  
3) Two quick blinks per second indicates Flash Detect is enabled.  
One blink per second means the Flash Detect is disabled.  
4) Push and release power button to switch modes.  
5) Push and hold the power button to save and exit the Flash  
Detect setting.

Performance and Economy modes  
(Only applies to Sea Dragon 2000F SL984 light)  
The Sea Dragon 2000F light (SL984) is set to “Performance”  
mode, which means it maintains constant brightness (lumens)  
even as the battery charge is depleted. The light can also be set  
to “Economy” mode, so the brightness gradually reduces as the  
battery charge drops, which doubles the battery life (burn time).  
To select between these two modes:  
1) With light in the OFF state, push and hold the power button  
for 7 seconds.  
2) Release the power button when the middle indicator light  
begins blinking.  
3) Two quick blinks per second means the light is set to  
Performance mode. One blink per second means the light is  
set to Economy mode.  
4) Push and release power button to switch between the two  
modes.  
5) Push and hold the power button to save and exit the mode  
setting.

Blinking and SOS mode  
(Only applies to Sea Dragon 1500F, 2100SF and 2500F lights)  
The Sea Dragon 1500F, 2100SF and 2500F lights include a  
blinking and SOS mode for emergency signal purposes.  
1) With the light in the OFF state, push and hold the power button  
for 4 seconds.  
2) Release the power button when the light starts blinking.  
3) Push and release the power button to switch between 1 second  
interval blinking and SOS Morris code signal.

XV. Troubleshooting Guide  
Light does not power ON  
Make sure battery is fully charged and contacts are clean.  
Replace battery if it has become wet or is damaged.  
Blue or dark pictures/videos  
Keep your shooting distance inside of 2ft to 3ft, depending on  
visibility and ambient light.  
If you are using only one light, considering adding another light  
(dual lights) or/and external flash accessory. The ideal set-up is a  
combination of a light plus flash.  
For the DC1400 and other SeaLife DC-series cameras, Consider  
purchasing the SeaLife Wide Angle Lens (SL975). The fisheye lens  
allows you to get closer to the subject and fit more into to picture  
frame.  
Pictures or Videos too red  
The camera’s white balance setting may not be set correctly. Refer  
For updated information and advice, please refer to the SeaLife  
dealer or service center for help.
