When I plug it into the charger, I can hear a little bit of static coming from the charging port itself - only happens when it's in the "wait...." mode! This really does not sound good. Is there water in the USB bulkhead? Never ever connect the 2C to USB power when the USB bulkhead is wet...

Hi,

The altimeter feature in the old 2N/2C is pretty much useless. Beeing an active open-source project >10 years ago this feature was added at some point and was left in there.

Hallo, Wir haben das heute Abend hier mehrfach nachgestellt. Es war mir nicht möglich das zu reproduzieren. Bitte probiere es nochmal. Einzige verbliebene, etwas theoretische, Situation wäre ein Wechsel innerhalb eines Tiefensamples (Also 10s auf Bailout und zurück auf CCR). Wenn Du möchtest, lese d...

The USB standard has long since ceased to be a standard as far as the power supply of all kinds of devices is concerned. With USB-C PD, there still seems to be a standard. But devices with USB-A plugs have been doing what they want for many years and accordingly you can now simply draw 1-2A from any...

Our charger draws up to 2A from USB. Any good powerbank can supply this.

Hi,

Nothing has changed on this point between 3.17 and 3.18.

What Decotype is stored in the internal logbook?

Wrong charger for this kind of OSTC.

Is the battery-% shown in yellow? Charger should be blinking in green with 1Hz or constant green. If the unit did not charge properly until tomorrow, please email us at info@heinrichsweikamp.com - maybe the charger is broken. Also: For the OSTC 2 (Mod. 2017 - the current iteration of the OSTC 2) you...

Make sure to use a proper USB Supply. 5V and at least 2A is recommended. Try a different one, sometimes these require communication with the USB device. Our chargers do not communicate and just try to draw the current they need. T4 is good and leave the unit charging then. 3.4V is quite low but far ...

"T4" is in front of the battery voltage? If it stays at 0% usually the battery type was not setup as required. You can change this setting from within the Reset menu -> Reset Battery.

I tried using an alternate (1.2V battery) and the computer turned on but placing it on the charging pad turned it red (so the charging element seems to be detecting it). 1.2V batteries will not be charged in the OSTC even if you setup T2. 1.2V NiMH batteries are not recommended in the OSTC plus due...

Wir schließen den Thread hier, denn parallel sind wir ja schon wegen des Drucksensorschadens per Mail in Kontakt.

Bitte kontaktiere uns in dem Fall bitte per Mail: info@heinrichsweikamp.com

Wir schließen diesen Thread, denn es geht ja gar nicht mehr um einen 2N.

Hi,

There are some header files in your logbook memory that are invalid. You need to reset the logbook from the reset menu in this case, sorry. The unit will reformat the logbook memory then and new dives will be stored properly.

Hallo,

Einfach die Tiefe merken, das Nitrox wird ja nicht jedes mal signifikant anders sein, und die MOD grundsätzlich nicht ausreizen.

Hallo,

Beim OSTC sport kannst Du die Taster einfach mal selber checken: https://www.facebook.com/heinrichsweika ... 5938565261

Meistens ist da nur Dreck oder Sand angesammelt. Da keine O-Ringe involviert sind, kann dabei auch nichts undicht werden.

Gruß,
Matthias

Die MOD steht nur im "Gas Setup" im Oberflächenmenü. Beim tauchen würdest Du dann eine Warnung bekommen wenn Du diese überschreitest. Wenn Du beim einstellen des Nitrox neben dem O2-Gehalt auch noch im Untermenü "Wechseltiefe" einmal auf "Reset auf MOD" aktivierst, steh...

Hallo, Wir müssen beide Taster zusammen austauschen. Die Reparatur ist sehr kompliziert und zeitaufwending, daher müssen wir 119,70 EUR (inkl. USt) plus Versand dafür verlangen. Die neuen Taster sind außerdem silber, nicht rot. Wenn der 2N sonst noch in Ordnung ist, lohnt sich das in der Regel schon...

SimonBrown wrote: ↑Monday 14. March 2022, 09:14 The computer is now alive and reporting battery 100% - can you confirm the battery should be T4 please? The serial number is 15813.

T4 is correct, but the 100% will be correct once the battery is fully charged and displayed in green, not yellow. See manual page 44.

Hi,

Please email us (or post here) the download "logfile", that contains technical information about the download process. You can generate it in Subsurface by checking the "Save libdivecopmputer logfile" box in the download window.

Hi, Our FAQ says: OSTC 2 / 4: It may be that the dive computer is in deep sleep mode because the battery has run down (before charging). In this case, the battery is disconnected from the rest of the electronics to protect it from deep discharge. This is deliberately implemented to protect the batte...

Hi, please post (or email) us the logfile (Check "Save libdivecopmputer logfile") that can be generated in Subsurface while downloading the dives. That will have some important information that might help us to help you. Downloading on MAC OS 12.2.1? See: https://subsurface.github.io/faq/#...

Hi, You have the 3,6V rechargeable battery in the unit? 1,2V NiMH batteries will not be recharged in the unit. Make sure "T2" Battery type is choosen, otherwise the battery charging is disabled. Also check the battery contact spring? Is it still shiny and golden? If not there might be some...
