As there doesn’t seem to be an in depth manual, I have some questions on how the DVR works.
1. I know the power button will make the unit turn on. How long will it remain on? Is there a way to manually turn it off when done.
2. Is it safe to remove the memory card when the unit appears to be off (and not in parking mode)? Last time I did this, I had to re-flash the firmware to return the DVR to normal function. For me, it was faster to remove the memory card to read on the PC.
3. Any other important “do’s“ and “don’ts” for the K2 we should keep in mind?
If you start the K2 via the Power Button, it will remain on till you switch it manually off. To do so, simply push the button again for some seconds.
Sure. I do the same when there are many videos to copy.
That's strange, as the SD Card has nothing to do with the firmware. I did many things to my spare K2, which normal users would not do, but it never lost its firmware or got unresponsive.
So I can only assume that your K2 simply needed a reset, which happens when you install the firmware. But you could have also used the reset button for this :-)
Not in terms of normal use.
