The values in the Tilt frame show the inclination angle (alignment
difference from the vertical) of the RT20A pole. Both readings are in
degrees. The N/S reading is the inclination in north-south direction, and
the E/W reading is the inclination in east-west direction. During the
operation the inclination values should be less than 8 degrees.
The Mode frame shows the operational status of the RT20A. In the
AUTO mode automatic tracking is enabled, whereas in the MAN mode
manual control is enabled. The mode is controlled with the
AUTO/MANUAL key in the Hand Terminal RTH21. The status data of
RT20A can also be seen on the hand terminal display.
NOTE
Set the antenna in AUTO Tracking mode.
