NOTES ON SCHEMATIC DIAGRAM
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 electrolytic capacitor, the expression “capacitance/withstand voltage” is used. (CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type (P.P.): Polypropylene type

• 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.
Same PI code — freq: different
(AF’S) PS: same PTY: same
[For example] Pickup and memorized to preset CH.
f 1 f 2 f 3
P 1 (PI cord) PS 1 (Station Name)
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.
f 5 f 4

1. Introduction of RDS for MD-X8H
MD-X8H 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, AFF AIRS, 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 — MD-X8H)
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 MD-X8H 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 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 MD-X8H EON is basically stand­by 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 ONTN station continue to keep EON stand-by.
3. EON-TI Don’t switch TNON during TN broadcast TA. (same item)
