Introduction
XM® Satellite Radio is a new and exciting audio experience on your
radio dial; it provides you with digital audio programming at the touch
of a button. By using two geo-stationary satellites, XM® radio provides
static and distortion-free sound, with a choice of 100 channels of diverse programming, including music, news, history, sports, and talk.
To make this system available to the motoring public, Audiovox has
engineered a state-of-the-art XM® Satellite Radio System, consisting
of a Satellite Antenna (purchased separately), a Satellite Radio Receiver Unit (RRU), a Satellite Radio RF Modulator, a Satellite Control
Unit (SCU) and an optional wireless remote control. By using the FM
section of any car stereo system, the RF signal information is demodulated and produces the audio output to your existing stereo
system speakers. Since XM® Satellite Radio will operate through the
FM stereo system, adjustment of the audio functions (volume, tone,
balance, etc.) is made by using the controls on the car radio, while
selection of the desired audio channel is made using the Satellite
Control Unit (SCU).

How the System Operates
Control of system functions is achieved by the wired SCU, which can
be conveniently mounted to the dashboard in a number of configurations. In addition, an optional wireless remote (Audiovox P/N SAT-RC)
to control SCU functions is also available. The XM® Satellite Radio
signals are received by the antenna and are routed to the RRU, whose

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 frequency 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.

1. Liquid Crystal Display (LCD): Presents a display of various
system functions, such as channel/category number, type of
broadcast, song title, performer(s), advisory/error messages,
etc.
2. Down Directional ( ) Button: When momentarily pressed,
channel number decreases with each press; when pressed and
held, the channel number decreases continuously. Release the
buttonwhen the desired channel number is displayed. When used
in conjunction with the Shift (SFT) button, the
MUTE
enabled.
3. Keypad Buttons 0-9: These buttons are used to directly enter a
desired channel number. They are also used when entering and
recalling preset channel numbers into memory.
4. Up Directional ( ) Button: When momentarily pressed,
channel number increases with each press; when pressed and
held, the channel number increases continuously. Release the
buttonwhen the desired channel number is displayed. When used
in conjunction with the Shift (SFT) button, the
SCAN
function is
enabled.

5. Infrared Detector: Provides detection of the infrared control
signal transmitted by an optional wireless remote control unit
(P/N SAT-RC) for remote operation. Make sure no obstructions
are blocking the signal path.
6. Shift (SFT) Button: When momentarily pressed, this button
provides access to additional functions, such as audio MUTE,
channel SCAN, direct channel access, category select, etc.
7. Power On/Off ( ) Button: Press this button to apply power
to the Satellite Radio Receiver. The associated stereo radio
must be turned on and off separately using its power switch.
8. Mute Function Button: Momentarily press the shift (SFT) but-
ton; then press and hold the down directional ( ) button to
enable the audio mute function. When enabled, the audio program is muted and the Mute icon ( ) appears in the lower
right corner of the SCU display . Press any button to exit the mute
function.
9. Scan Function Button: Momentarily press the shift (SFT)
button; then press and hold the Up directional ( ) button to
enable the up channel scan function. When enabled, each
channel is scanned in the up direction for 10 seconds before
moving on to the next active channel. Each channel number
appears in reverse image (white-on-black) format. This permits channel preview or introductory sampling of channel programming. Press any button to exit the scan function.
SATELLITE RADIO RECEIVER (RRU)
The RRU is the central data receiving equipment required to process
the satellite signals from the external antenna; it contains the processing logic needed to recognize, decode and distribute the incoming program information. The RRU is typically installed under the seat or in the
trunk/rear of the vehicle.
SATELLITE RADIO RF MODULATOR
The RF Modulator receives the satellite RF signals from the RRU and
provides the necessary FM pass-band logic to recognize and pass these
signals on to your existing vehicle’s FM stereo system. So, when your
radio is tuned to one of the FM frequencies between 88.1MHz and
89.3MHz, you can enjoy XM® programming. The RF Modulator is typically mounted behind or under the dashboard.
