So TB, clicking once gives [low], clicking twice [fast beacon], etc.. ?
So unless you have a custom interface, I suspect you have a v2.2 firmware
because there are 2 different strobe-frequencies (beacon & strobe).
However, if you say it "once" started with burst at the first click, it could only
have been you once set high-bightness to a low-level function, or maybe
have a custom interface...
Aanyway, assuming you are not in UI1 (default), try clicking 8 times to
switch from UI, e.g. go back to UI1, or UI2...
Hope this helps, if not, you could always send it in an assembled Ti body to me
(not that you would be getting it back....
)
