3. Summary of CD-C470H/CD-C480H 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:
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 switching TN—ON station.
therefore ASPM is usefull not only for PTY search but also for rapid EON switching. Anyway CD-C470H/CD-C480H’s EON is
basically stand-by and receiving method, along with the Guidelines for EON implementation.

1. Introduction of RDS for CD-C470H
CD-C470H/CD-C480H 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.
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.

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
