4.1.6Returning all parameters to standard default setting

Setting the standard default setting parameter to 3, all parameters can be returned to the those factory

default settings. (Except for )

When is set to , the set up parameter is displayed. Setting the setup parameter enable to operate, See 4.1.4.

Note: For more details on the standard default setting parameter , see 5.7.
