Functional Operation
Functional operation of the system is controlled by the buttons on the SCU; i.e., the sequence in which they are pressed and the length of time button activation occurs.
POWERING UP THE SYSTEM
After the system has been properly installed it can be powered on in the following manner:
1.Apply power to the vehicle’s radio.
2.Apply power to the Satellite System Control Unit SCU by momentarily pressing (1 second) the Power On/Off button ( 
).
3.Tune the vehicle’s radio to a selected FM frequency between
88.1MHz and 89.3MHz. If you are not sure which frequency to select, use the radio’s SEEK, SCAN or TUNE function to scroll through the frequencies until the satellite signal is played through the speakers. NOTE: The default FM frequency is 88.5MHz.
4.Enter this frequency into memory using one of the preset buttons on the vehicle’s radio; make note of the FM band and preset number.
5.After the correct frequency is identified and entered into the radio’s memory, the SCU will display the preview channel (CH184) if the SIRIUS® service is being activated for the first time (see DISPLAYING THE IDENTIFICA TION (ID) CODE). If the SIRIUS® service was previously activated, the SCU will return to the SIRIUS® channel used when the system was last turned off.
DISPLAYING THE IDENTIFICATION (ID) CODE
Once the system is installed you must first subscribe to the SIRIUS® Radio service to activate the system. The SIRIUS® Radio service uses an ID code to identify your radio. This code is needed to subscribe to SIRIUS® Radio, and if needed, is also used to report any problems should there be any in the future.
To display the radio ID code, proceed as follows:
1.To display the ID Code enter (SFT)+0+(SFT)
2.Make a note of your radio ID Number
3.Contact SIRIUS® Radio on the web, or by phone, to
subscribe to the service.

4.Direct Channel access.
The following subsections describe the procedure for each of the op- tions.
NOTE: If the SIRIUS® signal reception appears to be noisy or contains audible background static, try switching to another FM frequency. Refer to Direct FM Frequency Selection for details on how to select another FM frequency.
