Step 2 • The X-Axis is automatically pre-selected as the axis to be precisely
aligned. Press the X/Y button to change to the Y-axis if desired.
During this process the cross-axis is automatically reset to 0.000%
grade.
• The cross axis is at 0.000% grade when 'OK' is shown on the display.
• On the second control point adjust the Rod-Eye receiver on the grade
rod and make sure it is located in the on-grade position on the axis
selected (solid bar or solid tone). This part of step 2 is very
important.
• When you're done press STAR to continue.
Once STAR is pressed, the cross axis grade will change from 0.000% to
+5.000%.
As a result the laser beam signal on the receiver will most likely change
the elevation indication from the 'on-grade' position to either a 'high or
low' position. This is because the Rugby is not mechanically aligned and
the laser will no longer be giving an on grade signal. This is where the
electronic Axis Alignment is used.
Step 3 Carefully watch the arrows (laser beam) on the receiver.
•Use the UP / DOWN buttons to move the laser beam once again on
the center.
• Select between Speed 1, 2 or 3 which is available in both directions.
• One push will start moving the beam in slow speed.
• A second push will move the beam at medium speed.
• A third push will move the beam at highest speed.
• During this process an arrow symbol is shown.
If the arrow symbol stops flashing the maximum limit is reached
and the laser beam does not move anymore. (If the laser beam did
not pass the 'on-grade' position on the receiver please consider
re-orientating the laser instrument).
• To stop the laser beam movement press STAR.
• If the Rod-Eye receiver shows an UP arrow displayed, use the
DOWN arrow on the remote control to return to 'on-grade'.
• If the Rod-Eye receiver shows a DOWN arrow, then use the UP
arrow on the remote control to return to 'on-grade'.
