The Link123 Plus app is compatible with Android smart phones and tablets running Android version 5.0 or higher. If your phone/tablet is running on an older Android Version, the Link123 Plus app will not appear in the Google Play Store. Please try updating the Android version on your device or consider using a newer Android device running Android 5.0 or higher.
The following are updates to the DC2000 instruction manual included with the camera.
Please email us at email@example.com if you find any discrepancies in the instruction manual.
The SeaLife DC2000 was originally released with firmware version V1.00. In May 2017, SeaLife released firmware update V1.01, which fixes a lock-up bug when shooting in RAW+JPEG mode. If you have the original firmware V1.00, we recommend updating it to V1.01 or beta version V1.08 (see below). The firmware version installed on your camera will be displayed on the lower right side of the LCD display when powering on the camera. More information about the firmware update is available on the SeaLife website at https://www.sealife-cameras.com/firmware.
On June 26, 2018, SeaLife released beta firmware version v1.08, which includes auto focus accuracy along with many other enhancements. More information about this beta firmware update is available on the SeaLife website at https://www.sealife-cameras.com/firmware. The firmware has passed our internal testing and does not contain any known bugs. Please report any bugs to firstname.lastname@example.org. Note: You can always switch back to official firmware release version v1.01 at any time.
What is BETA firmware? Beta refers to the phase in firmware or software development between the alpha phase and the release phase where the firmware is installed on newly manufactured cameras. Beta firmware is generally considered “complete” by the software developer but still requires some real-world testing before it’s officially released.
A. Visually inspect the inside button reachs (shown below) for cracks. If the reach is cracked, it needs to be replaced by an authorized SeaLife Service Center in your country. SeaLife offers a free DC2000 Button Reach Kit (item # SL74112) that includes one of each reach used in the DC2000 UW housing.
B. Using a Torx T5 screwdriver, check if any of the reach screws has come loose. Fingertip tighten any loose screws using the Torx T5 screwdriver. Do not overtighten.
C. If you replace the shutter button reach, avoid disassembling the shutter button assembly by keeping the shutter button pushed down when the reash of reach screw is removed. If the external shutter button comes out (as shown below), make sure the slignment feature is aligned before tightening the screw.
D. If any of the buttons stick or up/down action is not smooth, there may be sand trapped under the buttons. Soak sealed housing in fresh water for 20 minutes to dissolve any salt trapped under the buttons. Hold the housing underwater and push each button 25 times to flush out any sand. If the buttons are still sticky, contact the authorized SeaLife Service Center in your country for thorough cleaning and lubing.
Some DC2000 owners have informed us that their camera sometimes powers on by itself and waiting to establish a wireless connection. The camera displays “Waiting for Mobile Phone to Connect”, which may drain the battery unless the camera is powered off or battery is removed.
After further investigation, we believe the root cause is related to certain apps installed on the individual’s smart phone. Some apps, like Garmin Connect or Fitbit, use Bluetooth to automatically connect to their respective devices. These apps may constantly hunt for a Bluetooth connection, resulting in unintentionally powering on other Bluetooth devices, like the DC2000. We found that GoPro Hero 5 cameras are experiencing the same issue (See https://community.gopro.com/t5/Cameras/GoPro-Hero-5-Black-Turning-On-By-Itself/td-p/16106/page/7). We are continuing to investigate the matter and will post updates to this web page.
Keep in mind that while you may not have one of these fitness apps installed on your phone, another nearby smartphones may be the source.
To address this potential issue, we have added a “Bluetooth On/Off” setting to firmware update beta v1.08. The Bluetooth factory default setting is “On”. If you experience the DC2000 camera powering on by itself, please turn the Bluetooth setting to “Off”. The camera will operate normally when Bluetooth setting is Off. Just remember to turn Bluetooth setting On when trying to make wireless connection with your smartphone or tablet.
Please report any information that you may have on apps causing the DC2000 to wake-up or other possible causes for this issue by emailing email@example.com. Again, we are continuing to investigate the matter and will post updates to this web page. Thank you for your patience and understanding.
Although the DC2000 features wireless connection to your Apple or Android smartphone/tablet, there is a faster alternative for importing DC2000 photos/videos directly to your smart device. Here’s how:
For Android phones/tablets – You will need an “On-the-Go” USB adapter for your phone tablet, which is readily available online. The adapter converts your device’s charging port to a standard USB port.
Connect the USB to your phone/tablet. Connect the DC2000 USB cable to the camera and USB adapter. Power on the camera. Open “My Files” app located in your device system tools. There you will find all the photos/videos saved in your camera.
For iPhone/iPad Devices: Apple manufacturers a Lightning to SD Card Camera Reader accessory that allows you to import photos/videos from a SD or micro SD memory card directly to your iPhone or iPad. This is a faster alternative to using the DC2000’s wireless connection for importing files.
iPad connected to Apple card reader
The Lightning to SD Card Camera reader accessory is available at Apple stores. Here are instructions for importing photos/videos to your iPad or iPhone:
1. Remove the micro SD memory card from your DC2000 and insert it into the SD card adapter. That converts the micro SD card to a standard sized SD card that fits into the card reader slot. Your micro SD card should have included the SD card adapter.
SD Card Adapter (left) and micro SD card (right)
2. Insert the SD card into the Lightning card reader and connect the card reader to your iPhone or iPad.
3. Open the Photo app and select the “import” tab on the bottom right of the app. Select the files you want to import. The selected photo and video files will be saved to your iPhone/iPad’s photo gallery.
Follow these steps to ensure the optical cable is securely connected to the Flash Link adapter:
A. Insert the non-coiled end of the optical cable (A) through one of the grabber holes of the Flash Link adapter (B).
B. Pull about 2” (5cm) of the optical cable through the grabber hole and insert the end of the cable into the other hole as shown below. Push cable end down into the hole until it comes to a stop.
C. Pull the other end of the camera to remove some of the extra slack, leaving about 1” (2.5cm) of cable bend as shown below. It is normal for thin layer of cable sheathing to be scratched off during this procedure.
This is most likely caused by using the wrong USB cable or the USB cable is damaged. The USB cable included with the DC2000 camera includes a ferrite core and is specially designed for data transfer and charging. Only use the DC2000 USB cable for connecting camera to a computer or charging.
Other types of USB cables may fit into the camera but may not make a data connection. For example, the USB cable included with the DC2000 battery charger (SL 7405) will also fit the camera but will not make a data connection.
The housing wrist strap included with the DC2000 UW camera attaches to the housing as shown below. Note: The clip is used for attaching the camera to your BCD (Buoyancy Control Device) D-ring.
The DC2000 camera is compatible with Micro SD/SDHC/SDXC/UHS-1 memory cards up to 64GB. Using 128GB cards may result in read/write error and camera lock up. One 64GB card can store 11,781 high resolution 20MP images, 1,356 high resolution RAW+JPEG images or 8 hours full HD 1080p video.
We also recommend memory cards with 10MB/s read/write speed, which are marked with , , Using a card with faster read/write speed will not make the camera operate any faster and may result in compatibility issues.
Avoid memory cards made by unfamiliar brands. Established brands of memory cards include SanDisk, Kingston, PNY, Samsung, Panasonic and Transcend.
There are a few possible factors that may cause a lock-up to occur:
A. If the camera is set to RAW+JPEG and Auto Review is OFF and the memory card is empty, the camera will lock-up. This issue has been fixed with firmware update v1.01 and beta v1.04. For more information about the firmware update, please visit the SeaLife website at https://www.sealife-cameras.com/firmware. To temporarily fix this issue until you update the firmware, simply take one JPG picture before setting camera to RAW+JPEG.
B. Use of a non-compatible memory card: We recommend using a micro SD, SDHC, SDXC and UHS-1 card with memory capacity up to 64GB. Using a 128GB or higher memory card may result in a lock-up issue.
C. We also recommend cards with at least 10MB/s read/write speed, which are marked with , , or
Using a card with faster read/write speed will not make the camera operate any faster and may result in compatibility issues.
D. The memory card has not been formatted and/or has erroneous files saved on the card. We recommend formatting memory cards before initial use. It’s also advised to format the card and perform system reset (“Reset All”) every couple of months in order to maintain optimal performance. Important: Formatting will erase all files saved on the memory card, please make sure to download your images/videos before formatting the card. The “Format” and “Reset All” functions are located in the camera’s system settings menu.
The SL975 fisheye lens accessory works with the DC2000 camera when used underwater. On land, the camera will not focus with the fisheye lens attached. The camera may be set to any focus setting (i.e. Auto Focus, Macro or Super Macro), except for infinity.
The battery included with the DC2000 camera can be charged inside the camera. In February 2017, SeaLife launched an external battery charger (item SL 7405), which may be purchased at your local authorized SeaLife dealer for $29.95. For more details, please visit sealife-cameras.com.
Follow these steps to ensure smooth operation of the mode dial at depths greater than 100ft (30m):
1. Synchronize the mode dial of inner camera with the UW housing mode dial before sealing the housing.
2. After sealing the camera inside the housing, rotate the mode dial in any direction and then return it to the desired mode setting. This will automatically seat the mode dial gears. If the gear teeth are not seated on land or at shallower depths, it may be difficult to rotate the dial at depth.

Here are steps for establishing a wireless connection between the camera and link:
A. Power on the camera.
B. Launch the Link123 Plus app on your smart device.
C. Select “Enable Camera’s Wifi” on your smart device to display a list of cameras within wireless range. The list will include one or more cameras starting with “abcam” and followed by 7 digits corresponding to the camera’s serial #.
D. Select your camera from the list [the one that matches your camera’s serial #.]
E. After waking up the camera, the camera will display a message, “Waiting for the mobile phone connection.”
F. Go to the WiFi Settings menu on your smart device and select your camera from the list of available hot spots. Again, your camera name (SSID) will be displayed as “abcam” followed by 7 digits corresponding to your camera’s serial #.
G. Enter the default password “12345678”. The password and camera name (SSID) may be changed later on.
H. Close the WiFi settings menu and launch the Link 123 Plus app again.
I. Select OK (Enter App) on your smart device.
If a wireless connection was successfully established, you will see a live view from the camera displayed on your smart device. If connection was not successful, reboot your camera and start over at step a).
A. The camera must have date/time setup completed before attempting to connect to Link123 Plus app.
B. Some Android smart phones and tablets will continue searching for another wireless connection after you established WiFi connection with the camera. The result is the wireless connection between your phone and camera will be dropped. The solution is to temporarily turn off your phone 3G/4G Data or put the phone in airplane mode and then turn on WiFi. Both of these methods result in your phone’s data turned off and WiFi turned on.
C. If you have installed a VPN [virtual private network] app on your smart phone or tablet, disable the VPN before attempting to establish wireless connection with the DC2000 camera. The VPN app may interfere with the ability to wirelessly connect to the cameras.
After downloading videos from your DC2000 camera to Link123 Plus app, you can playback videos within the Link123 Plus app. The downloaded videos will not appear in the Android device Gallery app; however, the files are saved to the “My Files” app included with your smartphone/tablet. Here’s where the downloaded video files are saved. This only applies to Android devices and not iPhones/iPads.
You can add a shortcut to your home screen so video files are only one click away. There are many free “file browser apps” available in the Google Playstore. For example, the “ES File Explorer” app is one that we have tested and works well.
RAW+JPEG setting will be blocked-out (gray) under the following conditions:
A. Exposure Bracketing is enabled
B. Photo Size is NOT set to 20M
C. Image Ratio is NOT set to 3:2
D. Camera set to Intelligent Auto, Land SCN or Panorama modes. RAW+JPEG is only possible in Program, UW SCN modes, Manual, Aperture Priority or Shutter Priority.
Open the waterproof door by sliding the lock right (1) and latch down (2), as shown below. When closing the waterproof door, push down tightly on the door and slide the latch up (2). The lock will automatically engage.
The DC2000’s autofocus system requires sufficient lighting and contrast to focus on a subject. If the subject is in low light or blending in with foreground/background (i.e. low contrast), the camera will have a difficult time focusing on the intended subject. Another possible cause for out-of-focus pics is shooting in low visibility conditions. The camera may try to focus on the debris suspended in the water. Here are some tips for capturing sharp pictures:
A. Make sure you have the correct focus setting:
B. For still images, pushing the shutter button halfway will set the camera’s auto focus. Focus squares will appear on the LCD to indicate what subject the camera is focusing on. Green squares indicate the camera has found a subject to focus on. Red square indicates the camera could not find a subject to focus on.
C. For videos, the video start/stop button does not have a halfway point. Pushing the video button will set the camera’s focus and begin recording. The Auto focus setting only applies to pictures and not to video. You may turn on the Continuous AF Video setting, so the camera will check and adjust focus while recording videos very few seconds. This setting is better used for close-up videos where you know that the shooting distance throughout the video clip will change. Shooting video beyond 3ft (90cm) with Continuous AF enabled may be disruptive as the camera constantly refocuses when it doesn’t need to.
D. When taking pictures beyond 3ft (90cm) shooting distance, set the camera to Infinity focus setting. This locks the auto focus to infinity and objects beyond 3ft (90cm) will be in focus. This setting is also ideal when shooting larger moving subjects, like sharks and mantas.
E. Use photo-video light to illuminate the subject
F. Set AF Area setting to Center when the subject you want to focus on is positioned in the center of the image frame.
Humid air or water drops trapped inside the underwater housing and inner camera may condense on the cooler glass lens port and cause fogging. Here is the best way to prevent fogging:
A. Do not allow any water drops to enter the inside of the housing or camera’s battery compartment. Even one water drop can evaporate and condense (fog) on the lens port.
B. Inner camera must be completely dry before inserting it into the UW housing. To minimize chance of fogging, do not expose inner camera to moisture before use in dive housing. Using the inner camera underwater or in wet environment without the housing will trap water drops in the small crevices, so it is important to allow camera to thoroughly dry before using it inside the housing. Inner camera may appear to be completely dry, but still have residual water trapped in the small crevices.
C. Load the camera and housing in a dry environment, like an air-conditioned room. This will help to avoid trapping humid air inside.
D. Avoid letting the camera get hot or sit in direct sunlight.
E. Avoid opening the housing in a humid environment. If you do change the battery between 2-tank dives, make sure you and the camera are dry before opening the housing.
F. Use a fresh Moisture Muncher desiccant capsule (item # SL 911) inside the housing.
G. If using the waterproof inner camera in wet environments (without the UW housing), allow the camera to completely dry before inserting it into the UW housing. Water trapped in the camera’s speaker and microphone holes may evaporate inside the housing and cause fogging to occur.
H. If the housing or camera lens fogs, do this:
If you followed the above advice and the camera or housing still fogs, contact your local authorized SeaLife dealer or the distributor/service center in your country for repair service.
The DC2000 UW housing and inner camera uses marine-grade stainless steel or anodized aluminum hardware suitable for saltwater and marine environments. If not properly cared for, rust stains and corrosion may appear on the stainless steel surfaces. Make sure to soak the sealed housing in fresh water for 20 minutes to fully dissolve any trapped salt residue. Push each of the buttons multiple times while the housing is soaking to remove any sand and debris trapped underneath the buttons. Allow the housing to completely 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 cabin and cargo pressure in airplanes can create a vacuum seal inside the housing, making it hard to open the housing door after landing. Do not use tools to pry open the housing! Open the latch and firmly grab and lift the door to open the housing. To prevent this vacuum lock effect, leaving the housing door open during air travel. Make sure to pack the housing in such a way as to protect the o-ring from damage and dirt.
The first edition DC2000 instruction manual has slightly incorrect focus distance specifications. The corrected focus distances are:
Note: The above focus settings only apply to still image and not videos. The camera will adjust and lock focus after pushing the video start button. When Continuous AF Video is turned on, the camera will check and adjust focus every few seconds.
