Installation / Wiring Precautions 11 Your Xpress XM 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 four vertical bars; four bars represent the strongest signal. The other is a higher resolution signal strength indicator screen which allows you to optimally aim your XM Antenna. This screen shows Terrestrial and Satellite indications in a horizontal bar graph presentation, with a minus (-) sign on the left and a plus (+) sign on the right. To access and use this screen, refer to the Xpress XM Satellite Radio Receiver User Guide. Adjust the antenna location until the maximum number of "Satellite" bars is displayed. The Xpress XM Receiver will receive programming as long as either the satellite or terrestrial signal has at least two bars displayed. Selecting a position with the maximum number of "Satellite" bars displayed will ensure a consistently strong signal.
