It is because the IF coil in the FM front end section has been best adjusted in the factory so that its further adjustment is not needed at the field.

· 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. 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. --f1 f2 ---

f9 f 10 f 11 f 12 f13 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-C621H CD-C621H 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-C621H) 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-C621H 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 AF M FAIRS) 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 to ON 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 station. 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-C621H EON is basically stand-by and receiving method, along with the Guidelines for EON implementation.

CD-C621H
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. Even if switch back ON TN station continue to keep EON stand-by. Don't switch TN ON during TN broadcast TA. (same item) EON can be cancelled during receiving ON station by pressing EON button if necessary and switch back ONTN. EON stand-by is perfectly cancelled (cleared) by pressing EON button 2 times during stand-by or power OFF or Tun Up/Down or change band or recall pre-set CH. After setting EON stand-by, stand-by items can be confirmed by pressing EON button one time. EON button function: · EON setting · Confirm stand-by items · Cancel (ONTN) · EON clear cancel (2 times) 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". 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. Don't switch TN ON during TN broadcast same specified PTY. (same item of PTY) Switch TNON TN station one cycle. Never switch TN ON1 ON2 Other net to other net station. 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". 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. 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. 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". No linkage volume, power ON/OFF, and switch function. Applications This programme does not carry traffic announcements nor does it refer, via EON, to a programme that does. This programmecarries EON information about another programme which gives traffic information. This programme carries traffic announcements but none are being broadcast at present and may also carry EON information about other traffic announcements. A traffic announcement is being broadcast on this programme at present.

RDS (Radio Data System) OPERATION
Descriptions of the PTY (Programme Type) codes, TP (Traffic Programme) and TA (Traffic Announcement) With the CD-C621H, you can search for and receive the following PTY, TP and TA signals.

FINANCE:
Stock Market reports, commerce, trading etc.
RDS is a broadcasting service which a growing number of FM stations are now providing. It allows these FM stations 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 announcements, and the TA (Traffic Announcement) will appear whilst a traffic announcement is being received. EON will appear whilst the EON (Enhanced Other Networks information) data is being broadcast. The PTYI (Dynamic PTY Indicator) will appear whilst the Dynamic PTY station is being received.
AFFAIRS: SOCIAL:
Topical programme expanding or enlarging upon the news, generally in different presentation style or concept, including debate, or analysis. Programmes whose purpose is to impart advice in the widest sense.
For programmes targeted at a young audience, primarily for entertainment and interest, rather than where the objective is to educate.
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.
INFO: RELIGION: SPORT: PHONE IN: TRAVEL: EDUCATE:
Programme intended primarily to educate, of which the formal element is fundamental. All radio plays and serials. Programmes concerned with any aspect of national or regional culture, including language, theatre, etc. Programmes about the natural sciences and technology. Programme concerned with any aspect of sport.
Programmes about people and things that influence them individually or in groups. Includes: sociology, history, geography, psychology and society. Any aspect of beliefs and faiths, involving a God or Gods, the nature of existence and ethics. Involving members of the public expressing their views either by phone or at a public forum.
