There is a normal and a professional mode. But I'm not able to reach the professional mode. If I turn the light off and on in the low setting the Flashlight remains in the normal mode.
My LT3 comes on in high, then if you switch levels to medium and then low, then turn off the light then switch it on again quickly you will get all the modes.
Doesn't work for me :( My Ld2 comes on in high. If i switch to low, then turn the light off and switch it on again it's still in nomal mode (strobe). I'll try to upload a Video.
Give it another try. I followed the scheme in post #3 and thought that I was still in the upper row.
In fact I was in the lower row, but the levels #2, #3, #4 and High are not much different so I thought that it was just bad switching, the same thing with the two SOS. You have to switch off/on rather quick in the lower row.
The term "standby" I do not understand, it is obvious to me that it is a Beacon mode that flashes every 8 sec's.
