The applications of HD parameters are reflected in the form of templates, and the system
provides several sets of commonly used templates for use. The HD parameters of each template are
independent of each other, and the parameters of
the second template will not be affected after
modifying the HD parameters of the first template, so please confirm the current template before
modifying the parameters.
