grade slope indication (l) will turn on
By holding down grade setting buttons (f) or (g) you can now enter your
desired slope on the x axis
To set grade on the y axis press button (b) x/y selection button, then the ‘Y’
indicator on the display screen will flash
Again using the grade setting buttons (f) & (g) you can now enter your
desired slope on the y axis
Once you have set you required grade slopes on the x & y axis, press x/y
selection button (b) so both the ‘X’ & ‘Y’ indicator on the display screen
remain on
The laser will continue to spin for 30 seconds and will then bring the x & y
values on the display screen back to 0.00%

Once your set slope is reached, this will be displayed on screen. i.e. X
