strongest possible satellite signal. If the
satellite signal is not available, you can
optimize it for a terrestrial signal (where
available).
b. Indoor installation on a flat surface
To aim your antenna at the satellite:
1. Set antenna flat against its base on a flat
(horizontal) surface.
2. Turn the base of the antenna so that the XM
logo is facing to the south if you are in the
eastern half of the U.S. and to the south/
southeast if you are in the western half.
3. Use the “Antenna Aiming” screen, as
described on the previous page, to opti-
mize antenna tilt angle and position.
4. If necessary, experiment with different
locations near a south-facing window or
outside.
c. Outdoor installation or indoor wall mounting
The antenna can also be attached vertically to
an external or internal wall if that is more
convenient than placing it on a horizontal
surface.
1. Holding your antenna up, find a wall
location that ensures a strong signal. It is
recommended that you use an extension
cord to temporarily locate your XR9 antenna
outdoors while optimizing the antenna
location with the Antenna Aiming screen.
2. Attach four screws to the wall using the
template provided. Use screws with head
sizes small enough to fit in the center of
each of the four holes but large enough not
to pop out of the elongated sections.
Leave1/8 inch of the screw shanks behind
the heads sticking out of the wall.
3. Tilt the antenna fully back on the base,
place the antenna base on the four screw
heads with the antenna pivot at the top, and
pull down approximately 1/4 inch until the
base is firmly secured. Note that the XM
logo will be upside down when the antenna
is properly installed.
4. Tilt the antenna away from the wall/base
until the signal strength is optimized.
