5. RADIO DESCRIPTION Radio frequency band Radio broadcasts use the radio frequency bands shown in the table below. Service area The service areas of AM and FM broadcasts are vastly different. Sometimes an AM broadcast can be received very clearly but an FM stereo broadcast cannot. FM stereo has the smallest service area, and is prone to pick up static and other types of interference such as noise. *a FM (Stereo) *b FM (Monaural) *c AM Radio reception problems HINT: In addition to static, other problems such as "phasing", "multipath" and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself. Phasing AM broadcasts are susceptible to electrical interference and another kind of interference called phasing. Occurring only at night, phasing is the interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off the ionosphere and the other signal is received directly from the transmitter. *a Phasing *b Ionosphere Multipath Multipath is a type of interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off buildings or mountains and the other signal is received directly from the transmitter. *a Multipath Fade out Fade out is caused by objects (buildings, mountains and other large obstructions) that deflect part of a signal, resulting in a weaker signal when the object is between the transmitter and vehicle. High frequency radio waves, such as FM broadcasts, are easily deflected by obstructions. Low frequency radio waves, such as AM broadcasts, are less likely to be deflected. *a Fade Out Noise problem Technicians must have a clear understanding about each customer's noise complaint. Use the following table to diagnose noise problems. Radio Frequency Noise Occurrence Condition Presumable Cause AM Noise occurs in a specific area Foreign noise Noise occurs when listening to an intermittent broadcast An identical program transmitted from multiple towers can cause noise where the signals overlap Noise occurs only at night Signal phasing FM Noise occurs while driving in a specific area Multipath resulting from a change in FM frequency
6. "HD Radio" FUNCTION OUTLINE (w/ HD Radio Function) The "HD Radio" system is a radio system that broadcasts in the IBOC (In-Band On-Channel) form that the iBiquity Co. has developed. By expanding the bandwidth per channel of conventional FM/AM bands, digital audio and data signals are additionally transmitted. "HD Radio" technology is manufactured under license from iBiquity Digital Corporation. U.S. and Foreign Patents. "HD Radio" and the HD and HD Radio logos are proprietary trademarks of iBiquity Digital Corp. Information for the music currently being listened to is stored in the system and can be transmitted to an "iPod" connected to the system. The information transferred to the "iPod" can be used for purchasing the music through the "iTunes" music store.
7. SDARS SYSTEM FUNCTION OUTLINE (w/ SDARS System) Satellite Digital Audio Radio Service (SDARS) is a satellite digital radio broadcast provided by Sirius XM Radio Inc. The broadcast (pay-type) is performed through satellites and terrestrial repeater networks. Several unique channels are available, and even if a vehicle changes locations, the same information can be received without breaks. Information such as song names, broadcast station names, etc. can be received. Also, traffic information can be received and displayed on the navigation screen. NOTE: To receive pay-type broadcasts, the customer must enter into a pay-type contract with XM Satellite Radio Inc. After entering into a contract, registration of the XM Radio ID is necessary. Also, if parts are replaced, the XM Radio ID must be re-registered. HINT: When disconnecting the cable from the negative (-) battery terminal, the broadcast station logo data will be initialized. It takes a while until the broadcast station logo data is updated to the latest one.
8. VEHICLE CUSTOMIZATION OUTLINE Customization of functions can also be customized on the multi-display assembly screen.

HINT: Items available for customization via the audio and visual system can also be customized by using the Techstream. Some customize parameters displayed on the Techstream will be displayed on the "Vehicle Settings" screen for the audio and visual system. Users can customize these items.
9. AUTOMATIC SOUND LEVELIZER (ASL) FUNCTION OUTLINE The Automatic Sound Levelizer (ASL) function automatically adjusts the audio system volume level in order to compensate for increased vehicle noise (vehicle noise tends to increase as vehicle speed increases). The ASL adjusts the volume level based upon vehicle speed signals that it receives from the combination meter assembly.
10. COMMUNICATION SYSTEM AVC-LAN Outline Components of the audio and visual system communicate with each other via the AVC-LAN. The AVC-LAN uses a twisted pair of wires for its communication lines. The master unit of the AVC-LAN is the radio receiver assembly. HINT: The radio receiver assembly has the resistance (60 to 80 ohms) necessary for communication. If a short or open circuit occurs in the AVC-LAN circuit, communication is interrupted and the system will not operate normally. Local Bus Communication Outline Components of the audio and visual system communicate with each other via the local bus. The local bus uses a twisted pair of wires for its communication lines. The master unit of the local bus is the radio receiver assembly. HINT: The radio receiver assembly has the resistance (108 to 132 ohms) necessary for communication. The combination meter assembly has the resistance (108 to 132 ohms) necessary for communication. If a short or open circuit occurs in the local bus circuit, communication is interrupted and the system will not operate normally.
