This is what I have in my Vegas. There is no crank up or down; simply a dial that rotates if you push up and it only rotates about 1/2 to 3/4 of a turn in total, full stop to full stop. It's quite poor to have such a small amount (almost non-existent) of documentation/instructions available.
Thanks to all who have chimed in offering help! It is truly appreciated.
