Keyboard risers
Before using your RollerMouse Pro, please
take a moment to adjust your keyboard.
If you are using other keyboards than
Contour's Balance Keyboard, you can use
the Keyboard risers to achieve the desired
keyboard height and angle. Simply place
the Keyboard risers under your keyboards
feet - as the keyboard was lying on the
table.
For a proper ergonomic position the front
edge of the the keyboard should be as
close to the Rollerbar as possible. We
recommend to use negative tilt helping
you to hold a neutral wrist position and
decreasing the extension of your fingers.
