Adjust the height of the yoke according to the height of the strings. Use the included screwdriver to adjust the arc-adjustment screw so the arc of the yoke and the arc formed by the strings are approximately the same. This arc will be about 184R with the yoke at its highest position (screw turned fully clockwise), and about 400R with the yoke at its lowest.
* Make sure not to overturn the screw, as this can lead to damage. When raising the yoke, turn the screw gradually, and stop turning it if you feel resistance.
