Mandatory Gas Time Alarm at beginning of the dive
-
@Ldive Agree. But as it always happens in the beginning of the dive it might also be a pressure related issue with the POD, just see all the screen prints, it happens all the time descending. The only strange thing is that when I switched back from my compass screen the Nautic wasn’t able to show Air/Air Time for several seconds and then it picked-up. This is something i’ve never seen before.
To answer your remarks, LED flashlights work on a pulse modulation fequency swiching the LED on/off for full power or dimmed use, that is not the problem as this is only the bulb intensity emitting frequency.
The issue is that LED Driver electronics can emit signals generating Radio Frequency Interference (RFI) in the 20 - 100 Khz. So while the actual lights themselves don’t broadcast RFI signals, the internal electrical drivers and switching power supplies can generate high-frequency electromagnetic noise which can intefere with the signals transmitted by the Tank POD to the Nautic. This can intefere with the POD signals and frequency inteference can drop communication in the range of 50-90%.
This is what I saw happening onder water as the Nautic was not able to show Air and Air time for switching back and fourth from the compass screen.
I will do some testing to hope that I can reproduce this behaviour above water.

I have been testing with 3 different LED flashlight on / near / close / up and down to the POD and the Nautic and the computer held its connection state as expected. So I do not expect that the RFI is causing the signal to become in-stable. Maybe a combination with POD pressure buildup in combination with RFI? I hope the Suunto dev teams can find the issue reading my POD and Nautic logs.

@hhouter i have the same problem. Since yesterday my Nautic gave the gas alarm. Everything is oke but the alarm came at 4 meters deep after 2 min. Then after 30 min my ocean that i use as a backup did the same. But funny thing it reset it self and gas time went up again. Very strange. Send the info to Suunto.
Monday i will try again. Then is my next dive planned -
This morning same problem.
At 1.17 min depth 1.47 meters depth gas alarm.
I hope Suunto comes with a solution for this. -
@MartinPadiPro which flashlight(s) do you use. Has Suunto support asked to send over the logs from both?
-
On top of all the other firmware issues the Nautic already has, I’m now dealing with this problem as well. This is becoming absolutely unacceptable.
-
@l.sillsuunto Only did one diving ( sidemount with 2 x transmitters )
Neither the Nautic ou Nautic S gave me the Gas time alarm
-
@Nandodiver Give it a few dives, all my budies have seen this alarm once or twice…You will get one also… It is something that needs to be fixed.

@hhouter I use a metalsub flashlight
I send the logs to amilco Benelux and to Suunto.
They say to have a look. Friday I go diving again. Let’s see what is going to happen. -
@hhouter this needs to be fixed
-
Yes, definitely a No-Go for a dive computer

@MartinPadiPro Can you check the tank pressure in the app? Should be available as an overlay. It would be interesting if the pressure is reported wrong or the watch just went nuts
