We occasionally get questions about SMVs, SMQVs and other products*, with regard to the “extra letter” that sometimes appears at the end of the model number on the badge label. The letters are E, L, M, H and V. What do these letters refer to and why are they there?
* You may also notice this on HH, HM, LMA, MM400C, UM400A, UT400 and WM units.
