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).
