RF output is supplied to the RF Modulator. The RF Modulator, in turn, is
capable of recognizing seven (7) FM frequencies; namely, 88.1MHz,
88.3MHz, 88.5MHz, 88.7MHz, 88.9MHz, 89.1MHz and 89.3MHz. The fre-
quency is selected using the FM band of the existing vehicle radio.
(The default FM frequency is 88.5MHz.) Select the FM frequency having
the least noise or static, and then use the SCU to choose the XM®
channel for your listening pleasure.
