process of going upstairs. Please
switch to "load plate mode" by
mode switch button in the
automatic adjustment mode of
the load plate and manually
adjust the turning Angle of the

stably on the stairs without
obvious shaking, and then switch
back to the running mode of the
track to carry out the upstairs
operation. Speed up when
CT420SC can climb smoothly.
