• FM 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.

Figure 14-1 ADJUSTMENT POINTS

CD SECTION

• Adjustment

Since this CD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups 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.

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifier output and the VREF reference voltage is compensated inside the IC.)

* Focus offset adjustment * Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing Fig.

14-2 EFBL)

(3) Gain adjustment (The gain is compensated inside the IC

so that the loop gain at the gain crossover frequency will be 0dB.)

• 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.

Each PI has AF’S list by individually.

Same PI code — freq: different

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: 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 stand-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 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.

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

5. EON-TI/PTY EON stand-by is perfectly cancelled (cleared) by pressing EON button 2 times during stand-by or power OFF

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

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

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.

12. EON-TI/PTY After switch TN → ON station. When ON station is NO RDS, NO signal, TA=OFF or different PTY items.

13. EON-TI/PTY Switch TN → ON in case of 2 more stations exist, comparing field strength and switch to the strongest station,

14. EON-TI/PTY No linkage volume, power ON/OFF, and switch function.

EON can be cancelled during receiving ON station by pressing EON button if necessary and switch back ON→TN. or Tun Up/Down or change band or recall pre-set CH.

• Confirm stand-by items

• Cancel (ON→TN)

• EON clear cancel (2 times) EON stand-by is automatically cancelled display “NO EON”. pressed then “NO TI” is indication the display.

Never switch TN → ON1 → ON2 → Other net to other net station. 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.

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 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 (Traf fic Announcement) will appear whilst a traf fic announce-

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.

When only the TA appears, an announcement is not being made.

Information Provided by RDS

With the CD-BA2010H, you can display three types of RDS

service. T o show them in the display, press the DISPLA Y MODE

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.
