While the dish rotates, the direction of the dish in relation to the vehicle’s
position will be displayed on the controller as a clock number.
(The windshield is always 12:00 o’clock: see Fig. 2, Page 3.)
This information can be used to determine when the dish is close to
pointing at the desired satellite.
IMPORTANT! You must continuously monitor the TV for signal strength while the
dish is rotating. DO NOT WATCH THE KING-DOME CONTROLLER.
