The DC1200 O-ring is made of a special low-durometer silicone material, which forms a very reliable wide seal when the housing is closed. The softer O-ring material may stick to the sealing surface of the closing door when opening the housing. Always make sure O-ring is clean, undamaged and correctly positioned in its groove prior to closing the housing. For detailed information about inspecting and caring for the DC1200 O-ring, please refer to page 60 to 63 of the DC1200 instruction manual.
The DC1200 is designed to work with the SeaLife SL970 Wide Angle Lens accessory and WILL NOT vignette underwater when set to Ext Flash, Sea or Snorkel mode. If you notice any vignetting in the picture, make sure the wide angle lens is completely pushed onto the lens port. Also make sure to “burp” out any air trapped between the Wide Angle Lens and camera housing lens port. If your SL970 wide angle lens does not make a tight, secure fit to your SeaLife camera, contact your local SL dealer or the SeaLife Service Center. In 2009, SeaLife has upgraded the snap on ring adapter of the wide angle lens for a more secure, tighter fit.

For the DC1200 camera, SeaLife recommends using a SDHC memory card up to 8GB, which holds 1400 large size, fine quality pictures or at least 90 minutes of continuous video. We have tested 16GB SDHC memory cards from various popular brands without encountering any problems.
The video mode will shoot continuously until the memory card is full or the shutter button is pushed. You can zoom in or out before recording video, but once the video starts recording the zoom cannot be adjusted unless you stop recording. Refer to page 32 of the DC1200 instruction manual for more information about video mode.

This problem is caused by not formatting the SD / SDHC memory card after it’s been used in another camera or electronic device. Make sure to format the memory card whenever it’s been used in another camera or electronic device.
Refer to page 20 of the DC1200 instruction manual for information on formatting the memory card.

SeaLife cameras are designed to work with any brand of SD memory card. SeaLife has performed extensive testing with various brands and size of SD / SDHC memory cards and we have not found any compatibility problems with brands like SanDisk, Panasonic, Toshiba, Delkin, Lexar, Kingston, PNY, Kodak, Polaroid, Kingmax and Eye-Fi (wifi card).
If you experience any performance problems with your SD memory card, it will most likely be a problem with the memory card. Check the following:
A. Make sure the card is not locked
B. Make sure the contacts on the care are clean and the card is not damaged.
If the memory card is still not working with your SeaLife camera, return it to the dealer where its was purchased and exchange it with another brand or size.

The DC1200 camera is compatible with Windows operating system version XP, Vista, 7.0 and higher, and MAC operating systems version 9.0 and higher. NO DRIVER IS NEEDED. The DC1200 camera will automatically connect to your computer when following the connection instructions outlined on page 54 of the instruction manual. Here are some tips if you are still having problems connecting the camera to your computer.
Humid air or water drops trapped inside the housing may condense on the cooler glass lens port and cause fogging. Here is the best way to prevent fogging:
If you followed the above advice and the camera still fogs, contact your local authorized SeaLife dealer or the distributor/service center in your country for repair service.
The DC1200 auto focus system has an effective range of 4″ (10cm) to infinity. Here is some important information on how to avoid taking out-of-focus pictures:
1. Focus settings
NORMAL – When you first turn on the camera it will be in “normal focus” [no icon] and the shooting range is 2ft (60cm) to infinity.
MACRO – Pushing the focus button once will change the focus setting from Normal focus to Macro focus. A flower icon appears on the top left of the LCD display. Macro focus is used for taking close-up pictures at a shooting distance of 4″ (10cm) to 3ft (90cm). Important: When you increase the optical zoom to maximum, the minimum shooting distance increases to about 20” (50cm) to infinity.
INFINITY – Push the focus button again to select “Infinity focus”. An infinity icon will appear on the top left of the LCD display. This will lock the camera to infinity, so anything beyond 3ft (90cm) shooting distance is in focus. This setting is very helpful in low light conditions or when the subject is low in contrast. When the camera is set to Infinity focus, the camera will also have the fastest shutter response time. Important: When using the SeaLife Wide Angle Lens (SL970), keep the focus setting on Normal or Macro, not infinity. The camera needs to focus through the wide angle lens to produce a sharp picture.
Use a fresh Moisture Muncher desiccant capsule (item # SL911) inside the housing.
2. The camera will focus on the subject located in the center of the picture. Align the square located in the center of the LCD over the subject. Subjects outside this square may not be in focus.
3. When taking a picture or shooting video, push and hold the shutter button half way to focus the camera. The focus frame in the center of the LCD display will turn green when the camera accurately determines the focus. If the focus square is red, the camera did not accurately determine the correct focus. If the focus frame is red, make sure the focus setting is correct and that there is sufficient lighting and try again.
A green focus frame indicates the auto focus is good.
A red frame indicates the camera is not focused on the subject.
4. In order for the camera to automatically focus on the subject there must be sufficient ambient light to illuminate the subject. The camera may not “see” the subject in low light. The subject must also have some contrast. For example, it is difficult for the camera to focus on a white wall with no contrast.
5. QUICK SHOT MODE: When Quick Shot is set to ON, the camera takes a picture without using the auto focus. This will speed up the camera’s response time (i.e. shutter lag). The focus will be locked to the shooting distance of the LAST picture taken before turning Quick Shot On. For example, with Quick Shot turned OFF, set the focus to Macro and take a picture of something at 6″ shooting distance. Now set the Quick Shot to ON and the camera focus will remain locked a shooting distance of 6″. When Quick Shot is ON, the focus frame on the camera’s LCD display will remain gray and not turn red or green. When powering off the camera, the Quick Shot focus distance is not saved and will be set to infinity focus. This mode is useful when taking a series of pictures at the same shooting distance and shutter response time is an important factor. Important: Remember to turn Quick Shot OFF if you want to use the camera’s auto focus

A dark area in the lower left corner of your image can occur when taking close-up pictures and the camera’s internal flash fires. The dark area or shadow is caused by the underwater housing lens extension which partially blocks the camera’s internal flash.
Notice the dark shadow area in the bottom left side of the picture. Turn the camera’s flash OFF or use the SeaLife external flash accessory (sold separately) to eliminate this problem.
There are a two ways to eliminate this shadow effect:

The DC1200 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 rinse off the underwater housing with fresh water after each use. It is best to soak the housing in fresh water for at least 5 minutes. Push each of the buttons and turn the zoom lever several times while the housing is soaking to remove any salt deposits under the buttons and zoom knob. Allow the housing to dry before storage. Keep all metal surfaces clean. If rust stains appear, use a soft bristle brush (like toothbrush) or clean moist cloth. A good 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 shaft of the metal buttons [which usually will result in the button sticking], contact your local authorized SeaLife dealer or the distributor/service center in your country for repair service.
The DC1200 camera can transfer data to the SD or SDHC memory card at 1.5 MB (megabytes per second) or 12Mb/s (megabits per second). To optimize the cameras recycle time, we recommend using a memory card with minimum “Class 2” speed (rated at read/write speed of 2MB/s). “Class 4” or “Class 6” cards are also okay, but avoid using “Class 10” memory cards as the read/write speed may cause compatibility problems. Please contact the memory card manufacturer for specifications on the cards read / write speed.
