Operation
RDS Operation
The AVR is equipped with RDS (Radio Data System), which brings a wide range of information to FM radio. RDS is a system for transmitting station call signs or network infor- mation, a description of station program type, text messages about the station or specifics of a musical selection, and the correct time.
RDS Tuning
When an FM station is tuned in and it contains RDS data, the AVR will automatically display the station’s call sign or other program service in the Main Information Display F.
RDS Display Options
The RDS system is capable of transmitting a wide variety of information in addition to the initial station call sign that appears when a station is first tuned. In normal RDS operation the display will indicate the station name, broadcast network or call letters. Pressing the RDS button BF enables you to cycle through the various data types in the following sequence:
•The station’s call letters (with some private stations other information too).
•The station’s frequency (FREQ).
•The Program Type (PTY) as shown in the list below.
•A “text” message (Radiotext, RT) containing special information from the broadcast station. Note that this message may scroll across the display to permit messages longer than the eight positions in the display. Depending on signal quality, it may take up to 30 seconds for the text message to appear; in that time, the word TEXT will flash in the Information Display when RT is selected.
•The current time of day (CT). Note that it may take up to two minutes for the time to appear, in that time the word TIME will flash in the information display when CT is selected. Please note that the accuracy of the time data is dependent on the radio station, not the AVR.
Some RDS stations may not include some of these additional features. If the data required for the selected mode is not being transmitted, the Main Information Display F will show a NO TYPE, NO TEXT or NO TIME message after the individual time out.
In any FM mode the RDS function requires a strong enough signal for proper operation.
Program Search (PTY)
An important feature of RDS is its capability of encoding broadcasts with Program Type (PTY) codes that indicate the type of material being broadcast.
You may search for a specific Program Type (PTY) by following these steps:
1.Press the RDS button BF until the current PTY is shown in the Main Information Display F.
2.While the PTY is shown, press the Preset Up/Down button 9E or hold them pressed to scroll through the list of available PTY types, as shown above. To simply search for the next station transmitting any RDS data, use the Preset Up/Down button 9E until RDS ONLY appears in the display.
3.Press any of the Tuning Up/Down buttons 7 , the tuner begins to scan the FM band upwards or downwards for the first station that has RDS data that matches the desired selection, and acceptable signal strength for quality reception.
4.The tuner will make up to one complete scan of the entire FM band for the next station that matches the desired PTY type and has acceptable reception quality. If no such station is found, the display will read NONE for some seconds and the tuner will return to the last FM station in use before the search.
NOTE: Many stations do not transmit a specific PTY. The display will show NONE, when such a station is selected and PTY is active.
NOTE: Some stations transmit constant traffic information. These stations can be found by selecting TRAFFIC. The AVR will find the appro- priate station, even if it is not broadcasting traf- fic information when the search is made.
