The mk1 goes into lock mode for no reason

Hello,

Two days ago I went diving, after only a month of not diving.

Already at the beginning of the first dive (immediately after activating the DESCENT MK1) I heard a beep and it became clear that the computer was locked and switched to dive meter | (lock for 24 hours).
As mentioned, I have not started the dive at all yet so there was no unusual event.

A similar thing happened to me about a year ago and to be honest, it's really disturbing.

Does anyone know this problem? Is it possible to prevent it and if so - how?
Thank you .

I've had my Mk1 for over 3.5 years and done nearly 500 dives and never, ever had it lock me out of a dive.

I'm having a hard time understanding what you did.

Before the dive started, did you start the Single-Gas or Multi-Gas activities? Have you used any other activities on the device in the last 24 hours?

Before the dive I turned on a single gas mode. I did not make any other use of the device several days before the dive.
Also, I notice that about two years ago another forum participant experienced the exact same problem and was unable to find a solution.

Sounds like your device is faulty. You should call Garmin Support.
