Screen 7 - Satellite Selection Control

Use Screen 7 (Figure 3.41) to specify whether to include or omit specific satellites
for tracking. Y indicates that the associated satellite are used; N means that are
not used.
Figure 3.41. Screen 7 - Satellite Selection Control
Also on this screen, you can put the receiver in AUTOMATIC selection or in
MANUAL mode by entering either a Y or an N in the AUTO SELECTION field. In
automatic mode, all satellites flagged Y are considered for tracking. Of these,
satellites that the receiver cannot lock on are replaced with others. Specifying Y
for a satellite instructs the receiver to try to lock on, and, if it cannot, to replace it
with another Y satellite. The receiver skips over those satellites designated N.
In manual mode (AUTO SELECTION is set to N), the letter Y in a satellite
instructs the receiver to select that satellite even when it is not visible. The
receiver does not replace it with any other satellite. In this mode, if you specify
more than 12 satellites, the receiver uses only the 12 that were displayed on the
12 channels on Screen 0 at the time you went to manual mode. If you specify
fewer than 12, the receiver tracks only the specified satellites.
To select the satellites you wish to use:
1. Press [e] to shift to data-entry mode. (A blinking cursor indicates that the
screen is in data-entry mode.)
2. Press the left and right arrows to highlight the field you want to change.
3. Press [8] to include the satellite or [1] to omit it.
4. When the flag is acceptable, press [e] to save it in memory.
Pressing [c] cancels all entries made since the first [e] was pressed.
