a. Plug the antenna into the ANT connector on the
back of the JXM900B.
b. Leave the antenna in place on the Boom Box,
or remove the antenna from its mount, uncoil
the antenna lead, and place it at the preferred
location inside or outside the home. If the
JXM900R display says “NO SIGNAL”, the
antenna needs to be repositioned. In addition,
even if you are receiving the XM signal, it is
recommended that you optimize the position of
your XM Antenna as described in this section
enabling you toreceive the strongest possible
signal and consistent, mute-free reception. Your
JXM900R display has two different signal-
strength indicators which will help you optimize
the antenna’s position: The first is a basic
signal strength indicator visible at the upper
right corner of the display screen during normal
listening. It has from zero to three vertical bars;
three bars represent the strongest signal. The
other is a higher resolution signal-strength
indicator screen showing Terrestrial and
Satellite indications which allow you to optimally
aim your XM Antenna. To access and use this
screen, refer to the JXM900R Satellite Radio
Receiver User Guide (128-7328).
7. Positioning the XM Antenna
The antenna supplied with the JXM900B is a high-
gain type that can receive XM’s signal from one of
XM’s satellites and/or, depending on where you live,
XM’s terrestrial repeaters. It is recommended that the
antenna be positioned near a south-facing window or
outdoors with a clear view of the southeastern sky in
order to receive the satellite signal. In some cases, it
will be possible to receive XM’s signal through
standard home walls or a roof. To position your
antenna, first set up the Boom Box as described
earlier in this user guide. Next, position the antenna
until you receive the strongest possible satellite sig-
nal. If the satellite signal is not available, you can op-
timize it for a terrestrial signal (where available).
