If the receiver is ON when the ignition is turned OFF, the receiver will power up when the ignition switch is turned to IGNITION.
Select a Frequency Band
Using the right thumb, press the MODE SEL switch on the right hand grip and release to cycle to the desired frequency band (mode) or press the soft key next to the frequency band displayed in the LCD to select a frequency band.
See B in Figure 1. The LCD highlights the selected band.
NOTE
Refer to ADVANCED AUDIO SYSTEM → Right Handlebar Controls → Receiver Frequency Bands. When a CD/MP3 disc is present in the CD slot and/or an auxiliary player is plugged into the AUX port, the MODE SEL switch will cycle through the CD and AUX modes as well as the frequency bands.
Volume
See D in Figure 1. At any time the receiver is playing, the volume can be adjusted by pressing the AUDIO switch up (+) to increase volume or down (-) to decrease volume.
AM vs FM Reception
Commercial radio broadcasting is either AM (Amplitude Modulation) or FM (Frequency Modulation).
AM
AM radio waves reflect off the ionosphere which results in consistent signal reception at a long range (up to 100 miles or 160 kilometers).
However, AM radio can be displaced by loud humming, popping and crackling noises. This is electrical interference caused by noise from vehicle ignitions, electric signs, power lines and electrical storms.
FM
The advantages of FM radio are high fidelity sound, stereo reception, a wide range of broadcasting formats and a signal that is free of electrical interference.
The disadvantage of FM radio is its short range. FM radio waves travel in straight lines, called "line-of-sight," therefore, FM signals cannot be received over the horizon. At the limit of a station's range, the reception may fade in and out when objects pass between the transmitter and the motorcycle.
FM Stereo vs FM Mono
See E in Figure 1. Normally, the Advanced Audio System plays FM signals in stereo. The LCD will indicate STEREO.
However, the stereo receiver has circuits which eliminate or minimize FM flutter due to weak stereo signals. The circuits detect a weak FM stereo signal and automatically blend it into a stronger FM mono signal. The transition is smooth and flutter-free because it occurs over a range of signal conditions, rather than at a minimum threshold.
When the system is automatically blending or is receiving an FM mono signal, the stereo indicator (STEREO) will disappear from LCD screen.
WB
See H in Figure 1. Broadcast by the National Oceanic and Atmospheric Administration (NOAA) National Weather Band (WB) frequencies are available in North America only.
To receive NOAA weather alerts while listening to other radio bands, highlight the Alert indicator in the WB display by pressing the soft key. An alert tone will automatically switch the receiver to the announcing WB channel regardless of which frequency band is playing.
When equipped with the CB module, use the soft key to highlight the Alert indicator in the LCD display. Weather alerts are announced over other audio and the Alert indicator is highlighted in the display.
Tuning a Radio Station
The radio has several tuning modes in each of the frequency bands: Manual, Seek, Scan, Preset Memory and Preset Scan.
Tuning in all three modes continuously wraps around the ends of the band.
Manual Tuning
To manually tune the radio to a different frequency:
Press the Up Arrow button or the Down Arrow button to select the frequency in that direction. Hold the selected arrow button, and after a short delay of 1.5 seconds, the radio will continue to change frequencies until the selected arrow button is released.
SEEK Tuning
See E in Figure 1. In SEEK, the radio tunes in to the next strong station.
Press and release the MODE SEL switch up (UP) to tune in the next strong station upward in the band. Press and release the switch down (DN) to tune in the next strong station downward in the band.
NOTE
The SEEK icon appears in the display as long as the receiver is seeking the next strong frequency. The SEEK icon disappears as soon as the receiver has tuned in the next station.
SCAN Tuning
In SCAN, the radio continuously tunes from one strong station to the next until the SCAN is cancelled.
See F in Figure 1. Press and hold the MODE SEL switch UP or DN approximately 5 seconds to scan the band for strong station signals. Each strong station remains tuned in for 8 seconds before the radio scans to the next station. The receiver will continue to scan until cancelled.
To select a station, cancel SCAN while the radio is tuned to that station. Press the MODE SEL switch UP or DN to cancel a SCAN moving up the band.
Preset Memory Tuning
Use the soft keys, 1, 2, 3, 4, and 5/Left Arrow as preset buttons to store frequently tuned stations.
NOTE
See C in Figure 1. AM can store 6 preset frequencies.
See E and F in Figure 1. Separate FM1 and FM2 bands allow the rider to store 2 sets of 5 preset FM frequencies (10 total). Use the More soft key to toggle between FM1 and FM2. The full range of FM frequencies can be selected in either FM1 or FM2.
To store a current station, press and hold any one of the preset buttons for 1.5 seconds. After an audible signal (a chirp), the station's frequency has been stored and the frequency will appear in the display next to the preset soft key.
To tune to a stored station, press and release the preset soft key.
Preset SCAN Tuning
See G in Figure 1. In preset SCAN, the radio continuously tunes from one preset station to the next until the preset SCAN is cancelled. A P.SC icon will display while preset SCAN is active.
In the FM band, press and hold the More soft key for approximately 3 seconds. Each preset station remains tuned in for 10 seconds before the radio moves to the next station.
To select a station, cancel preset SCAN while the radio is tuned to that station. Press the MODE SEL switch UP or DN to cancel a preset SCAN.
Adjusting Volume
Volume can be adjusted in any radio band.
See D in Figure 1. Volume is adjusted with the AUDIO switch on the left hand grip. Using left thumb, press the AUDIO switch up (+) to raise the volume or down (-) to lower the volume. The LCD displays the word Volume and a bar graph that changes length with the volume.
Press the MODE SELUP or DN to cancel the Audio/Setup display or wait 5 seconds after the AUDIO switch is released, the display switches to the currently selected frequency band.
See K in Figure 1. Volume can also be adjusted in Audio/Setup.
Press and release the AUDIO switch to enter the Audio/Setup display. Press and release the AUDIO switch to cycle through Bass, Treble, Fade and Display to Volume and the AUDIO switch to raise (+) or lower (-) the volume.
Mixing Bass and Treble
Bass and treble range adjustments can be applied to any Advanced Audio System source.
BASS: See I in Figure 1. Press AUDIO to display Bass Audio/Setup. Using the left thumb, press the AUDIO switch up (+) to increase the bass range or down (-) to lower the bass range. The LCD displays the word Bass and a dashed line that changes length with the setting. The short center dash indicates a middle setting.
TREBLE: See J in Figure 1. From Bass Audio/Setup, press and release AUDIO to sequence to Treble. Using the left thumb, press the AUDIO switch up (+) to increase the treble range or down (-) to lower the treble range.
See J in Figure 1. The LCD displays the word Treble and a bar graph that changes length with the setting. The short center dash indicates a middle setting.
Adjusting AVC
See L in Figure 1. Automatic Volume Control (AVC) automatically adjusts volume level to compensate for ambient noise associated with motorcycle speed.
If the AVC does not adequately compensate for ambient noise (or if it over compensates), enter the audio setup menu and select AVC. Compensation is adjusted with the AUDIO switch on the left hand grip. Using left thumb, press the AUDIO switch up (+) to raise the compensation level or down (-) to lower the compensation.
NOTE
Although the receiver AVC is preset at 3 bars, it is adjustable from zero bars (OFF) to four bars. At one bar, the volume does not change with motorcycle speed. The more bars displayed, the higher the volume increases with speed.
