RDS OPERATIONS

What you can do with RDS

RDS (Radio Data System) allows FM stations to send an additional signal along with their regular programme signals. For example, the stations send their station names, as well as information about what type of programme they broadcast, such as sports or music, etc.

Another advantage of RDS function is called “Enhanced Other Networks.” By using the Enhanced Other Networks data sent from a station, you can tune in to a different station of a different network broadcasting your favorite programme or traffic announcement while listening to another programme or to another source such as CD.

By receiving the RDS data, this unit can do the following:

•Tracing the same programme automatically (Network-Tracking Reception)

•Standby Reception of TA (Traffic Announcement) or your favorite programme

•PTY (Programme Type) search

•Programme search

•And some other functions

Tracing the same programme automatically (Network-Tracking Reception)

When driving in an area where FM reception is not good, the tuner built in this unit automatically tunes in to another RDS station, broadcasting the same programme with stronger signals. So, you can continue to listen to the same programme in its finest reception, no matter where you drive. (See the illustration on page 17.)

Two types of the RDS data are used to make Network-Tracking Reception work correctly —PI (Programme Identification) and AF (Alternative Frequency).

Without receiving these data correctly from the RDS station you are listening to, Network- Tracking Reception will not operate.

To use Network-Tracking Reception

You can select the different modes of network- tracking reception to continue listening to the same programme in its finest reception.

When shipped from the factory, “AF” is selected.

• AF:	Network-Tracking Reception is
	activated with Regionalization set to
	“off.”
	With this setting, the unit switches to
	another station within the same
	network when the received signals
	from the current station become
	weak. (In this mode, the programme
	may differ from the one currently
	received.)
	The AF indicator lights up but the
	REG indicator does not.

•AF REG: Network-Tracking Reception is activated with Regionalization set to “on.”

With this setting, the unit switches to another station, within the same network, broadcasting the same programme when the received signals from the current station become weak.

Both the AF indicator and the REG indicator light up.

• OFF:	Network-Tracking Reception is
	deactivated.
	Neither the AF indicator nor the REG
	indicator lights up.

AF and REG indicators

Note:

If a DAB tuner is connected and Alternative Reception (for DAB services) is activated, Network-Tracking Reception is also activated (“AF”) automatically. On the other hand, Network-Tracking Reception cannot be deactivated without deactivating Alternative Reception. (See page 42.)
