Settings
Sideways movement
The softer the setting, the more muscles are
required. We recommend setting the movement
to a reduced level initially then gradually
increasing the movement as much as possible
after continued use.
Settings: Turn the Aeris Swopper upside down
and turn the handwheel in the direction (+) or (-)
i. e. soft or hard.
