a. Plug the antenna into the ANT connector on the back of the XB9.
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 XR9 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 to receive the strongest possible signal and consistent, mute-free reception. Your XR9 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 XR9 Satellite Radio Receiver User Guide (128-7220).
7.Positioning the XM Antenna
The antenna supplied with the XB9 is a high-gain type that can receive XM’s signal from one of XM’s satel- lites and/or, depending on where you live, XM’s ter- restrial 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).
