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).
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

NOTE: Do not cut the antenna cable and attempt to
splice it or attach alternative connectors or
cable. The cable and connectors used in your
JXM900B are specially chosen and attached
at the factory to ensure that they will work
with XM’s unique frequency band. Use an XM-
approved antenna extension kit from your
local consumer electronics retailer. Failure to
do so could damage the unit.
a. Apply power to the JXM900B Boom Box as
outlined previously in section 3b and obtain an
audio output. If no audio is heard, move the
antenna to different positions on the surface
until an audio output is heard. This is the
desired antenna position and should be
marked.
cable; use protective grommets wherever
rough openings are encountered.
d. If the antenna is mounted outside, route the
cable from the antenna position to the interior
of the home, working the cable through the
basement,under a window sill, etc.; make
adjustments and take up slack whenever
necessary.
e. If outdoors, either leave the antenna in place
atop the JXM900B, or remove the antenna and
find a location free from overhead obstructions
such as tree branches, or the roof of a tent or
other temporary shelter.
f. Plug the antenna cable into the ANT connector
on the back of the Boom Box.
g
If not using battery power as the primary power
source, plug the female end of the DC Adapter
cable into the “DC 12V receptacle on the rear of
the Boom Box.
b. After determining the optimum position, turn
off JXM900B and Receiver power, disconnect the
power adapter from the wall outlet receptacle
(if indoors) and disconnect the antenna cable.
h. Plug the other end of the DC adapter cable
into a 110-volt wall receptacle. Apply power to
the Boom Box and Receiver.
i. You are now ready to enjoy XM programming
outdoors or within your home.
c. When indoors, plan the routing of the antenna
cable to the cradle. Make sure you avoid any
obstructions that could crimp, kink or twist the

Maintenance
Periodic Inspection
The JXM900B Boom Box should be inspected periodically for external damage. At least once every 30
days of use, perform the following checks:
1. Inspect the Receiver connector for loose, bent or broken pins, misalignment, etc.; make
sure the JXM900R connector is intact and exhibits no apparent damage.
2. Check the VOL control for freedom of motion without binding of any kind.
3. Check that the MODE pushbutton operates correctly in that it toggles between the Satellite
Radio output and the AUX input.
4. Make sure the antenna connector at the rear of the unit is free from damage of any kind and that
the antenna lead plug mates correctly and securely.
5. Make sure the DC 12V connector at the rear of the unit is also free from damage of any kind and
that the AC Adapter plug mates correctly and securely.
6. Check the antenna for any physical damage; make sure the antenna lead is secure and not
nicked or frayed.
7. Inspect the overall Boom Box case and speaker grilles for damage such as nicks, scratches
punctures, etc.
Cleaning the JXM900B Boom Box
When cleaning the Boom Box, make sure the AC Adapter is unplugged from the power source. Do not
use liquid cleaners or aerosol cleaners. Use a lint-free cloth lightly dampened with water for cleaning
the exterior of the Boom Box only.
