- `Manual Network Register`

  This field is used to specify whether to enable manually register the network.

  - **0** - Disable manually register the network.

  - **1** - Enable manually register the network.

  .. note:: If this function is enabled (value 1), the terminal filters the telecom operators according to the rules specified by the :ref:`AT@TOF <headlabel-refx-cmd-tof>` command (Mode is not 0), otherwise it will automatically search for all operators.
