Step Description

1. Set up the Rugby 870/880 at the base of a slope with no grade dialled into the
Rugby and with the X-axis pointing in the direction of the slope.

2. Adjust the height of the receiver on the rod at the base of the slope until the
on-grade (centreline) position is indicated on the receiver by:
• the centre bar
• the green flashing LED
• a solid audio tone
• the digital display

3. Move the rod with the receiver to the top of the slope. To start the Smart
Targeting process press the laser man button for 1.5 seconds. The receiver
shows SMT, then XSC for X-axis slope catching.

The Rugby 870/880 searches for the receiver until the on-grade position is
found. Once the on-grade position is found, the receiver flashes all three LEDs
simultaneously one time and the receiver returns to normal operation.

4. After this signal, the receiver can be moved and used as normal. The grade for
the sloped axis is displayed on the LCD and the Rugby now self-levels to this
new slope.

 To use Smart Targeting for the Y-axis, press the Y Button together with the
Laser Man Button for 1.5 seconds until the receiver shows YSC for Y-axis slope
catching.

 Using this procedure, you can set up either one or both axes.
