1. Cannot find Link123 Plus app in Google Play Store

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.

2. Instruction Manual updates/corrections

The following are updates to the DC2000 instruction manual included with the camera.

  1. Page 51 –UW White Balance section in the manual did not include the 3 underwater color correction settings:
    Blue Water Deep – Underwater color correction ideal for diving below 25ft/8m without external flash or photo-video light accessory. This WB setting is the default used by the Dive mode and ideal for most clear tropical waters. In darker conditions (e.g. underneath a ledge) or at depths greater than about 60ft/18m, the color correction will not be as effective and may result in dark or grainy pictures – consider using an external flash or photo-video light accessory, which works well at any depth.
    Blue Water Shallow – Underwater color correction ideal for snorkeling or diving above 25ft/8m without external flash or photo-video light accessory. This WB setting is the default used by the Snorkel mode and ideal for most clear tropical waters.
    Green Water – Underwater color correction ideal for ocean and fresh water with high concentration of algae. Water with high level of algae will take on a greenish color tone.
  2. Page 44 – The Underwater Scene Mode description for Snorkel Mode states the incorrect depth. It should be “25ft/8m” and not “33ft/10m”.

Please email us at info@sealife-cameras.com if you find any discrepancies in the instruction manual.

3. SeaLife DC2000 Firmware Updates

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 quality@sealife-cameras.com.  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.

4. DC2000 underwater housing shutter button not working

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.

5. Camera powers on by itself and displays “Waiting for Mobile Phone to Connect”

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 quality@sealife-cameras.com.  Again, we are continuing to investigate the matter and will post updates to this web page.  Thank you for your patience and understanding.

6. Wired connection from DC2000 camera to smartphone/tablet

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.

11. Camera locks-up or is unresponsive

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.

15. Camera not making wireless connection with Link123 Plus app

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).

Important Notes:

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.

19. Camera not focusing

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:

  • Auto Focus: 6″ to infinity (15cm to infinity)
  • Macro Focus: 3.5”-20” (9cm to 50cm)
  • Super Macro: 3.5”-20” (9cm to 50cm)
  • Infinity: 3ft – Infinity (90cm to infinity)

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.

20. Fogging on inside of camera or housing lens

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:

  • Load one fresh Moisture Muncher capsule inside the camera’s battery compartment and seal the camera for 1 to 2 days. This will dry out the inside of the camera.
  • Load one Moisture Muncher capsule inside the UW housing and seal the camera inside the housing for 1 to 2 days. This will dry out the inside of the housing and exterior of the camera.

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.

21. Tips for avoiding rust stains on stainless steel parts

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.

22. Housing is hard to open after air travel

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.

23. Focusing distance

The first edition DC2000 instruction manual has slightly incorrect focus distance specifications. The corrected focus distances are:

  • Auto Focus: 6” to Infinity (15cm to infinity)
  • Macro Focus: 3.5”-20” (9cm to 50cm)
  • Super Macro: 3.5”-20” (9cm to 50cm)
  • Infinity: 3ft – Infinity (90cm to infinity)

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.

Important Notes

  • When shooting video, the camera’s focus range is 3.5” (9cm) to infinity when set to regular AF, Macro, Super Macro or Infinity focus. Firmware update V1.08 allows the camera to use Infinity focus when shooting video, so all objects beyond 1m will be in focus depending on ambient light conditions and aperture setting.  See below for more details about minimum shooting distance when using Infinity focus setting.
  • When the camera is set to Infinity focus setting, the Continuous AF Photo and Continuous AF Video settings will be turned OFF and cannot be enabled.
  • When shooting video in regular AF or Macro focus, 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.  We recommend keeping Continuous AF Video turned OFF as the frequent focus adjustments disrupt the video and may cause audio interference.
  • The camera’s aperture setting will affect the minimum shooting distance when using infinity focus setting. A small aperture of f/11 has longer depth-of-field and closer minimum shooting distance compared to f/1.8.  The minimum shooting distance is 3ft (1m) when camera is using to f/4.5 or smaller aperture.  The minimum shooting distance for f/2.8 and f/1.8 is 6ft (2m) and 12ft (4m), respectively.   In order to control the aperture and depth of field, we recommend shooting pictures in Aperture Priority or Manual mode. Since video recording uses auto exposure, more ambient lighting or bright photo-video light is needed so the camera will use smaller aperture value.
