can be combined freely.
Each time a disc is changed, these adjustments are
performed automatically. Therefore, playback of each disc
can be performed under optimum conditions.

Notes:
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.

4. No adjust type (None adjusting circuit.)
5.Added EON button.
6. Need to change RDS logo due to the addition of EON feature.
7. Added EON—TI, EON—PTY function.
3. Summary of CD-BA2010H 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 automatically →stay
and listen to TA of ON station → switch back to TN station automatically 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 receiver
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-BA2010H EON is basically stand-by and receiving method, along with the Guidelines for EON implementation.
• ASPM SCAN: 87.50 MHz →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 2 f 3

P 2
PS 2
f 6

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 intentionally, never memorized (over write) at the same frequency.
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-BA2010H
CD-BA2010H 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-BA2010H)
1. PTY item: addedTA. (TTL18 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 stand-by →Light up
During receiving ON station. →blink.

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)

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”.
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.

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 stations of
AF'S are very weak or no good condition, then, switch back ON → TN automatically display "NO READY".

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 infor- mation 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 sta- tion name if sent) is displayed. The TP (Traffic Programme) will appear on the display when the received broadcast carries traffic announcements, and the TA(TrafficAnnouncement) will appear whilst atrafficannounce- ment 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 an- nouncement is being made. WhenonlytheTAappears, an announcement is not being made.
Information Provided by RDS
With the CD-BA2010H, you can display three types of RDS service.To show them in thedisplay,press the DISPLAYMODE button. Each time you press the DISPLAY MODE button, the display will change to show the following information.
Station names commonly known will be displayed. “NO PS” appears if no signal is being received. Programme type will be dis- played. “NO PTY” appears if no signal is being received. Radio text will be displayed. “NO RT” appears if no signal is being received. Station frequencies.

•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. Besides, the one with “Fusible” is a fuse
type.
•Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitor without such a symbol is microfarad. As to
electrolyticcapacitor,theexpression“capacitance/withstand
voltage” is used.
