Roll Offset Menu
2. Ensure the drill head is at its 12:00 position and that the transmitter is on.
Set Roll Offset Menu
3. Select Set the roll offset.
If you need to know the original roll value later (perhaps to change a transmitter frequency in-
bore as discussed on page 70), simply toggle to the Roll Offset option in the Settings menu,
and if Roll Offset is enabled, the original roll value displays at the bottom
of the screen after "Roll offset enabled".
When the roll offset function is enabled, the roll indicator will change to a
circle and “RO” appears at the bottom left of the roll indicator.
