Having trouble updating your Firmware? Read this:

You may encounter a firmware update failure where your LifeLine running firmware 0.64 or earlier is unable to update. The firmware update process will appear to start but the LifeLine will just reset and the firmware will not update. The software will report that it cannot find the LifeLine and ask if you can see it in "My Computer".

If this happens several times and you are unable to update your firmware, please use one of the following methods to completely run down your battery, then try the firmware update again.

Method 1 - Continuous Position Reports (MMSI # required)

  1. Ensure your LifeLine is registered and has an MMSI number entered, this method will not work without an MMSI number
  2. Go to the Apps tab and click on the Group Call button (software 0.3.61+)
    • This is the Advanced > Fleet Mode tab in older software versions
  3. Enter a Host Boat MMSI such as 123456789
  4. Select "Continuous Position Reports" and click "Apply Settings to LifeLine"
  5. The General tab should then say "Red Button - Continuous Position Reports" at the bottom
  6. Disconnect your LifeLine from your computer
  7. Press the Red button for three seconds to enable Continuous Position Reports (this is not distress mode)
  8. Leave your LifeLine running continuous position report mode until the battery is completely drained
  9. During position report mode the LifeLine will appear to go to sleep and wake up as part of the DSC cycle. This is normal and expected.

Method 2 - Transmit and/or long timeout (MMSI # not needed)

  1. Under Apps > Customize Settings set the Timeout (min) to 180
    • This is the Advanced > Settings tab in older software versions
  2. Disconnect your LifeLine from your computer
  3. Press the transmit button repeatedly or leave your LifeLine awake to run down the battery - it may take several hours to completely drain the battery
  4. Wake up the LifeLine if it shuts off to continue draining the battery
  5. Leave your LifeLine awake until it will no longer wake up when you push a button

For either of these methods transmitting on the chat channel will help run down the battery faster. When the LifeLine will no longer wake up from a button press, plug it in to your computer and connect to the software to try the firmware update again. It may take a few minutes of being plugged in for your LifeLine to wake up when it has been completely drained.

If after completely draining your battery you are still unable to update the firmware, please contact your local dive shop for help, or our tech support team at: or +1-604-241-1918.

We wish you safe diving and strongly encourage all Lifeline users to ensure that your firmware is up to date with v1.02.

Captain Mike and the team at Nautilus Lifeline.
