Defining the Wind Direction in VMG Mode

Use the following procedure to program in the direction of the wind so that the SC-1 can calculate your VMG:

1. Set the upper display to compass mode and the lower display to VMG mode. Bear-off to a dead run so you are moving straight downwind.
2. Unlock the buttons.
3. Put your thumb over the plus button and hold it there. You will see the display scroll upwards increasing one degree at a time. You can also scroll down by holding the minus button.
4. When the heading on the lower display matches the upper display, release your thumb

The SC-1 will beep and switch to showing you your VMG. The device will now use the angle you dialed in to determine your VMG.

Please Note: Increasing the display damping before beginning this procedure will help you get a steady reading on the upper display.
