Step Description
1. Set up the Rugby 840 at the base of a slope with the X-axis pointing in the
direction of the slope.
2. At the base of the slope, adjust the height of the Rod Eye 180 Digital Receiver
RF on the rod until the on-grade (centre-line) position is indicated on the
receiver by:
• the centre bar
• the green flashing LED
• a solid audio tone
• the digital display
3. Move to the top of the slope and press the laser man button for 5 seconds to
start the smart target and lock process. The receiver will show SMT, then XSL
during the X-axis slope lock process.
4. The Rugby 840 searches for the receiver until the on-grade position is found.
Once the on-grade position is found, the receiver will flash all three LEDs
simultaneously one time and the receiver returns to normal operation. The
display will show LOC while the receiver is in lock mode.

To turn off lock mode on the receiver, hold the power button for
1.5 seconds.
