Oeanic VT4: How do I reset it?

[By9468840]

hi everyone
I bought a used VT4 with just about 8 dives.
I have been going crazy trying to find out how to reset it's dive history. I know it is not a big deal but I got obsessed with it.
it is unbelievable that there is nothing mentioned in the operations manual or anything is written on the internet. It is the first time google actually failed me.
Can someone please tell me if VT4 can be set back to factory settings? or atleast the dive history can be erased?

Can't be done anywhere but at the factory. You just need to dive it until the data is overwritten. Set the sampling rate to 2 seconds, and do enough dives that the onboard log book hits 24 dives plus whatever is in there now. That will overwrite both memory chips.
