RDS is a broadcasting service which a growing number of FM stations are now providing. It allows these FM stqtions to send additional signals along with their regular programme signals. For example, the stations send their station names, and information about what type of programme they broadcast, such as sports or music, etc. When tuned to an FM station which provide the RDS service, the RDS will appear, the station frequency (and then the station name if sent) is displayed. The TP (Traffic Programme) will appear on the display when the received broadcast carries traffic annoucements, and the TA (Traffic Annoucement) will appear whilst a traffic announcement is being received. EON will appear whilst the EON (Enhanced Other Networks information) data is being broadcast. NEWS: AFFAIRS: INFO: EDUCATE: DRAMA: CULTURE: SCIENCE: VARIED: Note: When the TP and TA appear at the same time, an announcement is being made. When only the TA appears, an announcement is not being made. (See page 17.) Information Provided by RDS With the CD-C471H, you can display two types of RDS service. To show them in the display, press the DISPLAY MODE button. Each time you press the DISPLAY MODE button, the display will change to show the following information. PS (Programme Service): PTY (Progamme Type): Station Frequency: POP M: ROCK M: M.O.R. M: LIGHT M: CLASSICS: OTHER M: ALARM: NONE: TP: TA: News Topical programme expanding on the current news or affairs Programmes on medical service, weather forecast, etc. Educational programmes Radio plays Programmes on national or regional culture. Programmes on national sciences and technology. Other programmes like comedies or ceremonies Pop music Rock music Middle-of-the-road music (usually called "easy listening") Light music Classics Other music Emergency broadcasts no Programme type (receive only) Broadcasts which carry traffic announcements Traffic announcements are being broadcast at present. Note: When the unit is in the EON stand-by mode and a programme is selected, the unit will display "TI" instead of "TP" or "TA". Station names commonly known will be diaplayed. "NO PS" appears if no signal is being sent. Programme type will be diplayed. "NO PTY" appears if no signal is being sent. Station frequencies. – 14 – – 15 – Yes Yes Compare the field strength of current receiving signal. Is receiving signal stronger than signal which has same PI cord and is already memorized to preset memory ahead of this receiving time?

Pass No effect Pass No effect Pass No effect Pass No effect Repeat and continue with same format ASPM operation untill 108 MHz. After reached 108 MHz, displayed the TTL quantity of memorized stations. And return to the previous receiving freq. automatically. Begin to ASPM SCAN from the next CH-SPAN again. No Preset CH memory become full over? Yes Displayed the TTL quantity of memorized stations by ASPM operation on this time. And return to the previous receiving freq. automatically. CD-C471H CD-C471H • ASPM SCAN: 87.50MHz → 108.00 MHz. • Only RDS signal is memorized by ASPM because RDS signal has PI code and is suitable and convenient for ASPM operation. ASPM Comparing field strength, only one strongest RDS station is memorized of all stations (repeater relay stations) that have same PI code. f3 P 1 (PI cord) PS 1 (Station Name) f5 P2 PS 2 f4 --- f1 f2 --- Each PI has AF’S list by individually. Exa: P1 has f1, f2, f3 (same PTY). Same PI code — freq: different P2 has f4, f5 (same PTY). (AF’S) PS: same PTY: same [For example] Pickup and memorized to preset CH. f8 f9 f 10 f 11 f 12 f13 f6 f7 P3 PS 3 P4 PS 4 Select signals (f1, f5, f7, f10) are memorized in the preset memory by ASPM. • If tentative - ASPM operation is repeated intententionally, never memorized (over write) at the same frequecy. 1st time ASPM → strongest stations of each pi are memorized. ASPM is not only very usefull for PTY search, but also EON operation. 2nd time ASPM → 2nd strong stations of each pi are memorized and so on. PTY search function is equal to FM band search function as a result. 1. Introduction of RDS for CD-C471H CD-C471H RDS function is equal to adding EON feature to the current CD-C75H RDS. EON feature is EON—PTY and EON—TI. Although PTY and TI indicators are separated, PTY contains TI in the PTY items (software) like current PTY search items. NEWS, AFFAIRS, INFO, ALARM, TI (TTL 17 kinds) ↑ ↑ EON—PTY EON—TI Can select and stand-by Can select and stand-by EON—PTY and EON—TI are basically stand-by → receive the desired program of ON station. 2.The difference point from current CD-C75H RDS. (CD-C75H — CD-C471H) 1. PTY item: added TA.TTL 18 kind. 2. Each “TP”, “TA” ind. light up or go out individually. “TA” ind. doesn’t light up on current model, CD-C75H due to none EON—TI. 3. Added 3 indicators(in FL) due to adding EON feature. EON: Lights up only during receiving EON data (14A). TI: During EON-TI stand-by → Light up During receiving ON station. → blink. PTY: During EON-PTY stanb-by → Light up During receiving ON station. → blink. 4. No adjust type (None adjusting circuit.) 5. Added EON button. 6. Need to change RDS logo due to add EON feature. 7. Added EON—TI, EON—PTY function. 3. Summary of CD-C471H RDS—EON operation EON—PTY: Select and set the desired “PTY” → stand-by → switch to ON(other network) Station at the start of desired PTY automatically → stay and listen to PTY of ON station → switch back to TN(This net) station automatically at the end of PTY(ON) i.e. after changing to another PTY(except AFFAIRS) or cancelling to receive PTY of ON station midway. EON—TI: Select and set the “TI” → stand-by → switch to ON station at the start of traffic announcement automati cally → stay and listen to TA of ON station → switch back to TN station autmatically at the end of TA(ON). ie after TA(ON) is over or cancelled to receive TA of ON station midway. When switching TN → ON station. In case of exist 2 more stations having the desired(specified) “PTY” or “TI”, the receiver will select and switch toON station comparing field strength at the same time. But when the frequency of ON station exists in the preset-memory, then reciver switches straight to that ON station(CH), without comparing field strength so can make a quick switching from TN—ON sta tion. Preset memory takes priority of switching TN—ON station. therefore ASPM is usefull not only for PTY search but also for rapid EON switching. Anyway CD-C471H EON is basically stand-by and receiving method, along with the Guidelines for EON implementation. – 16 – CD-C471H EON summary notice for reference 1. EON-TI/PTY EON stand-by can be set, only when EON ind. lights up. While EON ind. goes out (NO EON STATION), EON stand-by can't be set. If the EON button is pressed, then “NO EON” is indication the display. 2. EON-TI/PTY Even if switch back ON→TN station continue to keep EON stand-by. 3. EON-TI Don’t switch TN→ON during TN broadcast TA. (same item) 4. EON-TI/PTY EON can be cancelled during receiving ON station by pressing EON button if necessary and switch back ON→TN. 5. EON-TI/PTY EON stand-by is perfectly cancelled (cleared) by pressing EON button 2 times during stand-by or powerOFF or Tun Up/ Down or change band or recall pre-set CH. 6. EON-TI/PTY After setting EON stand-by, stand-by items can be confirmed by pressing EON button one time. 7. EON-TI/PTY EON button function: •EON setting •Confirm stand-by items •Cancel (ON→TN) •EON clear cancel (2 times) 8. EON-TI/PTY After setting EON-TI and EON-PTY stand-by, if when EON data is not transmitted, EON ind goes out and EON stand-by is automatically cancelled display “NO EON”. 9. EON-TI EON-TI stand-by can't be set. When TP=0,TA=0(TN) even if EON ind. lights up and the EON button is pressed then “NO TI” is indication the display. 10. EON-PTY Don’t switch TN→ON during TN broadcast same specified PTY. (same item of PTY) 11. EON-TI/PTY Switch TN→ON→ TN station one cycle. Never switch TN→ON1→ON2→ Other net to other net station. 12. EON-TI/PTY After switch TN→ON station. When ON station is NO RDS, NO signal, TA=OFF or different PTY items. The receiver switch back ON→TN displaying “NO READY”. 13. During receive ON station. when ON station become to be NO RDS, NO signal, TA=ON to OFF or different PTY item, The receiver switch back ON→TN. 14. EON-TI/PTY Switch TN→ON in case of 2 more stations exist, comparing field strength and switch to the strongest station, if these signals are same strength, switch to the first previous station. If same frequency as AF'Sexists in the preset memory, then switch TN→ON (preset memory station) straight. In case of exist 2 more preset memories of AF’S,then switch to the preset CH which taken in EON DATA first, also in this case no concern to field strength. 15. Even if switch TN→ON preset memory straight, that ON station is very weak signal, then search another AF'S (ON) station comparing field strength and switch to the strongest station as a result. Of all atations of AF'S are very weak or no good condition, then, switch back ON→TN automatically display "NO READY". 16. EON-TI/PTY No linkage volume, power ON/OFF, and switch function. Traffic Programme code Traffic Announcement code (TP) (TA) Applications OFF OFF This programme does notcarry traffic announcements nor does it refer, via EON, to a programme that does. OFF ON This programmecarries EON information about another programme which gives traffic information. ON OFF This programme carries traffic announcements but none are being broadcast at present and may also carry EON information about other traffic announcements. ON ON A traffic announcement is being broadcast on this programme at present. – 17 – CD-C471H NOTES ON SCHEMATIC DIAGRAM • Resistor: To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor.
