Note:
data may have not been entered, or may have been entered
incorrectly. Check that the latitude, longitude, altitude, elevation
mask, GPS fix mode, and cable delay information was correctly
entered on the BTMONitor Installation screen. Entering latitude in
the longitude window, and vice versa, are common errors. If the
alarm persists, the window or wall may not a have a large enough
view of the sky for the system to stabilize. If possible, move the
antenna to a window or wall with an improved view of the sky.
