v. Place ART EL-OPERATE-ART AZ Switch S-401 on the navigational computer
chassis (see figure 21) to the ART AZ position.
Observe the azimuth
presentation on the CRT while rotating the ARTIFICIAL ANGLE VOLTS Control R-
402 on navigational computer chassis (see figure 21) fully clockwise and
then fully counterclockwise. A bright dot (cursor pulse) draws the azimuth
cursor on the CRT as you rotate the ANGLE VOLTS OUTPUT control.
