CDP: The first press of this submenu key displays the Code Domain
Power and also displays an arrow on the submenu key symbol (to indicate
that a sub menu is available).
When Code Domain Power (CDP) is selected, the screen displays all of
the selected Walsh Codes and the selected Walsh Codes zoom codes in a
graphical format. Depending upon the Walsh Code set parameter, this

Walsh Codes is selected, the top CDP graph displays the CDP in
bit-reversed order. The screen also displays the following Control channels
in table format: Pilot, Page, Sync, and Quick Page. If the marker is set on
the code, then the marker displays the code number, power, and code
type.
The codes are color coded as follows:
Pilot in Red
Page in Green
Sync in Blue
