How about single or double click? I do not have a sample with me now. For my VOSTRO, it took less than a second of hold time to switch to other flashing modes.
Received my second Vostro yesterday, unfortunately the led is not centred…….any suggestions on how to centre it? The centering ring has a lot of play. I have used double sided tape, but each time I tighten the bezzel, it pushes the ring out of centre. Compared to my first vostro, the hotspot is very blury and not getting same distance either.
