4.Press the course control knob, and then press [TURN/MENU] key once (twice for STBY mode) to close the menu.

5.Press the [TURN/MENU] key once to show the TURN menu.

6.Rotate the course control knob to select “RADIUS OF ORBIT”, and then press it to circumscribe the value with a double rectangle.

7.Rotate the course control knob to set the radius of orbit. (Setting range: 0.05 to 9.99 nm)

8.Press the course control knob.

9.Reduce boat’s speed less than 10 kt.

10.Rotate the [ENTER] knob to select "◄ SPIRAL" or "SPIRAL ►".

11.Press the course control knob to start the spiral function.

The message “START TO TURN BY FISHING MODE” appears, and the boat runs for the distance set at step 7, and then starts making a spiral similar to the figure on the previous page.

If the boat's speed becomes more than 10 kt while orbiting, the message "TOO FAST TO FISHING MODE. PLEASE SLOW DOWN LESS THAN 10 kt. PUSH MENU KEY TO CANCEL AND GO TO AUTO MODE." appears. Reduce boat’s speed less than 10 kt. In this case, the boat runs as shown on page 3-11.

12.To escape from the SPIRAL while it is in use, press [STBY] key.
