Setting Y axis slope -
This sets a grade in the Y axis.
Procedure – switch ON; the FRE-208 then auto levels. Press the red "G"
button on the Remote Control or laser's keypad & the "X" illuminates on the
screen.
Press the X/Y button ONCE only to scroll down to a flashing "Y". Using the top
two right hand buttons, set the % gradient value required.
The same buttons can be found on the Remote Control. Press X/Y button
ONCE again and the laser will adjust to this angle of slope, then rotate.
To return to Auto level, switch the laser OFF & ON again via the green button,
to reset the % values to zero. The Laser will wait to find true level, then
automatically restart, self levelled.
Setting both X & Y axis slope (dual grade) -
Proceed as above, but enter values for both X% & Y%
