Re: hwOS TECH: New Firmware 3.25
From this picture, your OSTC 3 looks quite "used"... Maybe we should have a look at this here?

Re: Ploywatch? Remove Scratches
Hi, I doubt that you can remove the scratches properly from the glass. I think you should leave it as it is rather than trying to polish it with questionable means. A protective film may even help to fill these scratches. This will make them barely visible (Same refractive index then the glass ...

Hello, In the past, we always counted up the version number for beta versions. For some years now, however, the firmware can be provided with a BETA flag and so there can be a 3.25 beta (a preliminary version for testing, so to speak) and a 3.25 stable. I'll make the appropriate forum post right now ...

Re: OSTC Sport Plus geht nicht in den Tauchmodus
Hallo,
mache bei dem OSTC mal ein Reboot. Was zeigt er dann als Druck/Temperatur an?
OSTC haben keinen Wasserkontakt, der Drucksensor erkennt (Wenn er normal funktioniert) den Tauchmodus über den Druckanstieg.

Re: OSTC 4 with 3x Solid-State Sensor
We'll have the OSTC4 back on stock soon (A few weeks). As Thorsten wrote the OSTC4 controls everything here, so this is not an independent solution. Demand for simple LED HUD is not very big, we might build one that is compatible with the OSTC4 using this multiplexer board but don't wait for it if ...

Hi,
It would be very interesting for us to know which GF parameters you have set. Even if the last stop is technically always at 0m, the OSTC should then simply display the NDL time again...

Re: Cave Edition
The operation of the cave mode is relatively complex and complicated. Due to the small user base, it is simply better for our support if this is not (currently) in the regular firmware. Here is the current manual, which also clearly shows the functions: Supplemental Manual for the Cave Mode Function ...
