The RS/RT/LT beam can be adjusted several ways:

LEFT/RIGHT - Turn the knob clockwise to adjust the beam towards the left or counter-clockwise to adjust the beam towards the right.
UP/DOWN - There are two mechanisms for adjusting beam height: a white lever for macro adjustments and a black hex knob for fine tuning.
The white macro lever has three positions: up, middle and down. This is handy for quick headlight adjustments when you have changing loads. e.g. Riding solo with no luggage vs. riding 2-up with full luggage. Up is the highest pointing beam and down is the lowest.
Up/down fine tuning: The black knob turned clockwise lowers the beam and turning it counter-clockwise raises it.
For countries where you drive on the right side of the road the low beam cutoff on the right side angles up. I'm pretty sure that the reason for this is to better illuminate road signs.
