The orange box controls which side the changes are made to, so yes. Hold the pages button until the orange box changes sides. If it's a touch graph then, touch & hold for a second the side you want to make changes to.
Guys, go read the frickin' manual. The "operational secrets" we reveal here are what some of us learn by reading the user manual! That's the book that comes in the box with the sonar - if you didn't throw it away with the box.
P.S.: If you threw it away or bought a unit used, the manuals are available for download from Lowrance.
