GENERAL INFORMATION

Reception

FM reception offers the advantages of low 
noise interference, minimal distortion, 
wide dynamic range, extended frequency 
response, and is usually broadcast in 
stereo. FM frequency waves are however 
relatively short and travel in a straight line 
and can therefore be impeded by 
obstructions, which may adversely affect 
reception in certain parts of the country. 
This is a condition known as Multipath 
Interference.

Whilst FM reception generally provides 
better quality sound, AM reception or 
Medium Waveband (MW) may prove 
superior in remote areas not covered by 
the shorter range FM transmitters.

When experiencing poor FM reception, 
background noise can be reduced by 
pressing the MODE button, selecting 
TREBLE and reducing the treble setting.

Radio Broadcast Data Systems (RBDS) 
and Traffic Announcements (TA)

Jaguar sound systems are equipped with 
Radio Broadcast Data System (RBDS) 
which assists in locating and remaining 
tuned to a selected radio station. When 
tuned to certain stations on the FM 
waveband, the radio decodes signals 
transmitted, to provide the following 
functions (dependent upon the service 
available):
• When RBDS is selected the station 

name is displayed in eight characters.

• Automatic retuning to follow network 

stations:

RBDS provides fully automatic radio 
tuning for network stations. It tunes to 
a signal not a frequency. RBDS will 
locate the strongest signal available 
for a given station.

• RBDS will automatically switch 

frequencies (AF Switching) as 
necessary. This function can be 
toggled off and on by pressing and 
holding the BAND button.

• RBDS Station/Programme type 

display and search:

RBDS displays information on the 
type of material broadcast by the 
station or programme that is on e.g. 
News, Classical, Rock etc. In 
addition to this function, the radio can 
search for a selected programme 
type.

• RBDS Priority Programme Type auto 

retuning (where broadcast):

Similar to Traffic Announcement this 
can be selected to interrupt and 
switch to the selected programme 
type e.g. News, for its duration.

• Local radio station Traffic Information 

(where broadcast):

RBDS provides travel information 
relevant to the vehicle location. On 
learning of a traffic problem, the 
authorities inform the nearest local 
radio station.

The traffic announcement (TA) is then 
broadcast by transmitters in the 
relevant area.

Provided TA has been selected, traffic 
announcements will interrupt radio or CD 
play, on all equipment with the RBDS 
feature. If the volume control is set at 
minimum it will automatically increase to 
an audible level for the duration of the 
traffic news flash.

When the traffic announcement has been 
completed, the system reverts to the 
driver’s original listening choice and 
volume setting.

RBDS operation

To activate RBDS, press the TA 
button and hold for at least two 
seconds until RBDS ON is 
displayed.

To deactivate RBDS, press the TA button 
and hold until RBDS OFF is displayed.

With the radio tuned to an RBDS station 
and RBDS activated, the radio gathers 
RBDS information and displays the 
service name/data.

If the radio is not tuned to an RBDS 
station, it will remain on that station and 
display the frequency, and RBDS will 
remain on in readiness for a signal.

When listening to a national network 
station, or a station that broadcasts on 
more than one frequency, the radio will 
retune to the strongest available signal 
(AF Switching). This ‘network following’ 
will continue throughout the journey. 
(Unselected presets will also receive new 
frequency information, if appropriate.)

When RBDS data is lost and no 
alternative frequency signal is available, 
the radio will stay on station, the display 
shows the frequency only and RBDS 
remains on in readiness for the signal to 
recover.

If the RBDS function does not respond 
correctly, see RBDS troubleshooting 
guide on page 289.

TA operation

To activate TA: Press the TA button 
momentarily (less than two seconds).

TA will appear in the display. The radio 
then checks that the station has RBDS TP 
(Traffic Programme); indicated by TP at 
the top of the display. If TP is not available 
on the current station, the display will 
show TP SEEK while it searches for a 
station that does have it.

If a TA station is not available, a beep is 
sounded and TA is removed from the 
display.

With TA activated, traffic announcements 
will interrupt radio or CD play. If set at a 
minimum, the volume will increase for the 
announcement, returning to normal 
setting afterwards. When receiving, the 
display will show TRAFFIC INFO.

To deactivate TA: Momentarily press TA.

Preset TA volume

When the radio is set to minimum volume 
and a traffic announcement occurs, the 
volume is raised to a preset level. This 
level can be adjusted by pressing and 
holding the MODE button for more than 
two seconds, then setting the volume 
level (which is displayed) between 1 (min.) 
and 6 (max.) by turning the volume control 
knob.

Programme Type (PTY)

(Where broadcast)

This has two functions: To display 
current station programme type 
and to select a programme type 
and retune to it.

Momentarily press the PTY button to 
display the current station programme 
type. Use the tuning buttons to cycle 
through the available programme types, 
press the PTY button again to activate a 
search for the selected programme type. 
If there is a station with the correct PTY 
then the radio will retune to it. If not, the 
radio will indicate NO PTY and return to 
the current station.

Priority Programme Type (PPTY)

Functions as an interrupt or as a ‘PTY 
Following’.

Press and hold the PTY button to activate 
the selected priority programme type, 
PPTY. The radio will now wait for RBDS 
information to indicate that a station has 
changed its programme type, e.g. to 
NEWS. The radio will now retune to the 
new station for the duration that it remains 
on that programme type.

If the current station is already on the 
selected priority programme type, then 
when this station is lost, the radio will 
attempt to find another with the correct 
programme type.

To cancel Priority Programme Type, press 
and hold the PTY button, the PTY 
indicator will clear from the display.

Note: TA and PPTY interrupt feature is 
also available in CD and audio modes.

TA and priority PTY interrupt skip

Interruptions for traffic announcements, 
news or other selected priority 
programme types, can be skipped by 
pressing TA during the interrupt. The 
radio returns to the previously selected 
audio source.

Note: 

•

Interrupt skip will not cancel activation 
of TA or PPTY and it will remain ready 
for the next interrupt.

•

TA, PTY and PPTY features are reliant 
upon the broadcast information from 
radio stations, and may be much 
better in some areas than others.

PTY31-alarm (where broadcast)

When using the radio with RBDS 
selected, a PTY31-ALARM service will 
operate, to alert on any crises of major 
national importance. When such a 
broadcast is made, ALARM will appear in 
the audio display.
