Operating the Mouse
1. Basic Functions
The Finalmouse x Ninja Air58 features standard left and right-click buttons, a scroll wheel (which also functions as a middle click), and side buttons for additional functionality. The ultralight design (weighing only 58 ounces) enhances quick movements and reduces fatigue during extended use.

DPI (Dots Per Inch) settings can be adjusted to control cursor sensitivity. Use the dedicated DPI button (if present) or the Finalmouse software to cycle through preset DPI levels or customize your own.
Maintenance
1. Cleaning
To maintain optimal performance, regularly clean your mouse. Use a soft, dry cloth to wipe the surface. For the sensor, use a cotton swab lightly dampened with isopropyl alcohol. Avoid excessive moisture.
2. Grip Stickers
The mouse may come with optional grip stickers to enhance tactile feel. Some users have reported that these stickers can leave a tacky residue over time. If this occurs, they can be carefully removed. Use a mild adhesive remover if necessary, testing on an inconspicuous area first.
