There are two ways to confirm that you have strong signal reception:
1. Signal strength meter: Some XM Ready systems display a signal
strength meter for determining signal strength. Refer to your XM
Ready audio system's user manual for more information. Otherwise,
use the Preview Channel to determine if you are receiving the signal.
2. Hear XM Preview Channel: If you are tuned to Channel 1 and hear the
audio, you are receiving satisfactory signal strength to receive the XM
service. If you do not hear any audio, it means your antenna is not
receiving an adequate satellite or terrestrial repeater signal and must
be moved to a more appropriate location. Once you can hear Channel
1 broadcast clearly and consistently, you are ready to activate your
service.
