v.64 firmware update is available for download at www.nautiluslifeline.com. We now have more than 7000 Lifeline 2-way marine radio and GPS units in the field and have been listening intently to user feedback. We are immensely gratified with reports from many users who have already put their Lifelines to good use in difficult situations. Unfortunately, there have also been several incidents in which units didn't work because the battery charge was low and a couple of incidents when units switched off unexpectedly. This firmware update incorporates the following improvements:
i. Self-diagnostic test. Depress the orange button 3 times to enter self test mode. Position indicating light will test and flash. Battery voltage will be measured to ensure adequate capacity for 30 minutes of talk time and 24 hours emergency distress. Followed by a transmit load test, measurement of internal circuit resistance and a battery voltage droop test. If all parameters are working properly, the self-test will conclude with the message "good to go". Press the orange button once more and you are ready to go diving. NOTE: we highly recommend that before any dive weekend or dive trip, you charge the battery to 100%, inspect the 0-ring and usb port cover to ensure they are perfectly clean and installed correctly, and run the self-diagnostic test..
ii. Manual activation of the position indicating light "strobe". Press the green button twice to manually activate 2 light flashes every 30 seconds to catch the attention of your diveboat. Press any button to turn this feature off. The light will also turn off automatically leaving enough battery reserve for 30 minutes of talk time and 24 hours of distress transmission.
iii. Lifelines shutting off unexpectedly. 3 Lifelines have experienced a power down during normal operation. To ensure your Lifeline is working perfectly, we recommend the following test: Ensure you have updated your firmware to v.64. Turn your unit on. Point the antenna at a metal object and hold the antenna 1/2" away from the object. Metal object can be a cookie sheet, fire extinguisher, fridge or almost anything metal. Depress the green button for 3 seconds. If your unit shuts down, please call or email us right away.
We wish you safe diving and strongly encourage all Lifeline users to ensure that your firmware is up to date with v.64.
Captain Mike and the team at the Nautilus Lifeline.
