OOps, just realised you got the mini MKII I have that light too. Try loosening the head slightly and pressing it in 10 times to get into menu. You will have to hold down once there. LMK is it works. Disregard the following P2 info.
Clearance items sold as is without warranty, so good luck getting help with it. I really hope you do get some suggestions to fix it.
I haven’t been happy with the previous clearance 4-7 lights I got but I still went for this deal. Mine will be delivered today.
Prestine packaging… things can be repackaged. And I am sure the tolerances are inspected during manufacturing and get sorted accordingly. Clearance items are most likely the assembled lights with parts that should have been rejected.
If mine shows similar issues and I can resolve it, I will post my fixes. As a guess your driver pill may need to be tightened inside the head. Might also be a bad SW. What batts you using?
