1: Description of the "FM IF Adjustment" is not carried on this
Manual. 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. When replacing the
FM front end assembly, no adjustment is needed either.
2: The parts in the FM front end section are prepared in a
complete unit, so you can't obtain each part individually

RDS (Radio Data System) OPERATION
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.
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.
■
Information Provided by RDS
With the CD-C611H, you can display three 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): Station names commonly
known will be displayed. "NO PS" appears if no signal is being received.
PTY (Programme Type): Programme type will be dis-
played. "NO PTY" appears if no sig- nal is being received.
RT (Radio Text): Radio text will be displayed.
"NO RT" appears if no signal is being received.
Station Frequency: Station frequencies.

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-C3H 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 sta
tion. Preset memory takes priority of switchingTN—ON station.
therefore ASPM is usefull not only for PTY search but also for rapid EON switching. Anyway CD-C607H/611H EON is basi-
cally stand-by and receiving method, along with the Guidelines for EON implementation.
• 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.
Same PI code — freq: different
(AF’S)
PS: same
PTY: same
Each PI has AF’S list by individually.
Exa: P1 has f1, f2, f3(same PTY).
P2 has f4, f5(same PTY).
[For example] Pickup and memorized to preset CH.
f 1
f 2 f 3
P 1 (PI cord)
PS 1 (Station Name)
f 5 f 4
P 2
PS 2
f 6
f 7 f 8
P 3
PS 3
f 9 f 10
f 11 f 12 f13
P 4
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-C607H/611H
CD-C607H/611H 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-C607H/611H)
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.

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 thestrongest
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.
