RDS services

follows:
Notes

functions may be available.

or if the station you are tuned to is not transmitting
RDS data.
Setting AF and TA

Press (AF/TA) repeatedly until the
desired setting appears.
Storing RDS stations with the AF and
TA setting
You can preset RDS stations along with the AF/
TA setting. If you use the BTM function, only
RDS stations are stored with the same AF/TA
setting.
If you preset manually, you can preset both RDS
and non-RDS stations with the AF/TA setting for
each.
1 Set AF/TA, then store the station with BTM or
manually.
Receiving emergency
announcements
With AF or TA on, the emergency
announcements will automatically interrupt the
currently selected source.
Tip
If you adjust the volume level during a traffic
announcement, that level will be stored into memory
for subsequent traffic announcements, independently
from the regular volume level.
Staying with one regional program

setting restricts reception to a specific region, so
you will not be switched to another regional
station with a stronger frequency.

area, set “REG-OFF” in setup during FM
reception (page 20).
