). If the station
is not broadcasting an RDS signal, the dis-
play will show a blinking PT indication.
4. CLOCK TIME. A time and date display
broadcast by the station. If the station is
not broadcasting an RDS signal, the dis-
play will show a blinking CT indication.
5. RADIO TEXT. Scrolling text messages broad-
cast by the station. If the station is not broad-
casting an RDS signal, the display will show
a blinking RT indication.
PTY Button
The PTY search function scans for RDS stations
broadcasting a particular type of program.
1. Press the PTY button. The current RDS pro-
gram content type appears in the display.
2. If desired, change to a different PROGRAM
TYPE using the DOWN/UP buttons to scroll
through the list.
3. Press the PTY button a second time within
5 seconds. The tuner will attempt to find
an RDS station broadcasting the selected
type of program. If the button is not pressed
within 5 seconds after selecting a program
type, the PTY function will be cancelled.
4. If no station is located for the desired con-
tent type, the tuner will return to the last
previously tuned station.
5. Cancel the PTY function by pressing any
button (except DIMMER or FM MONO).
TP Button
Searches for an RDS station broadcasting traffic
information programming:
1. Press the TP button. The tuner will attempt
to find an RDS station broadcasting the
traffic programming.
2. If no station is located, the tuner will return
to the last previously tuned station.
3. Cancel the TP function by pressing any
button (except DIMMER or FM MONO).
TA Button
Searches for an RDS station broadcasting
special traffic announcements:
1. Press the TA button. The tuner will attempt
to find an RDS station broadcasting traf-
fic announcements.
2. If no station is located, the tuner will re-
turn to the last previously tuned station.
3. Cancel the TA function by pressing any
button (except DIMMER or FM MONO).
AF Button
In some cases, an RDS station is part of a
network of stations broadcasting the same
programming (for example, BBC1 program-
ming in the UK may be available at several
different frequencies). Stations broadcasting
this programming may transmit an RDS data
signal providing the tuner with a list of alter-
nate frequencies where this programming is
available. If this data list is transmitted, an AF
indicator will appear in the display.
The AF button is used to scan the alternate
frequencies to find a stronger signal. The button
is only functional when the AF indicator is lit.
1. Press the AF button. The tuner will scan each
of the alternate frequencies for the same
programming in the stored list and tune to
the strongest signal.
2. If no station is located, the tuner will return
to the last previously tuned station.
3. If the signal strength of the new station is
weaker, the tuner will revert to the previ-
ously tuned station.
4. Cancel the AF function by pressing any
button (except DIMMER or FM MONO).
Additional Tuning Features
The following buttons provide features which
may be used to improve FM reception and/
or provide additional functionality:
FM MONO Button
The FM MONO button changes the FM mode
from stereo reception to mono reception. In
stereo mode, a stereo signal will be heard if
the station is broadcasting a stereo signal and
there is sufficient signal strength. A stereo in-
dicator will light in the display. In mono mode,
a mono signal will be heard even if the sta-
tion is broadcasting a stereo signal.
NOTE
:
Switching to mono mode can be a use-
ful way to improve the reception of weak or
distant FM signals. Less signal strength is re-
quired for clean mono reception than for ste-
reo reception.
ANT ATT Button
Sometimes known as a LOCAL/DISTANCE
switch, the ANT ATT button reduces the sig-
nal level at the FM antenna input. For the best
reception of stations located some distance
away, this button should be in the default or
OFF position. However, if you are located in
an urban area very close to the radio trans-
mitter, the incoming signal may be high enough
to overload the FM inputs. Press this button to
reduce the incoming signal. When activated,
a LOC indicator appears in the display. Press
the button again to toggle back to normal op-
eration. This switch only effects FM reception.
FM IF NARROW Button
FM reception works by receiving and decod-
ing a carrier signal centered at the tuned fre-
quency. To accommodate broadcast stations
that may be misadjusted off this carrier fre-
quency, the receiver accepts signals slightly
to either side of the tuned frequency. This
generally provides satisfactory performance.
If you are located in an urban area with a large
number of stations at closely spaced frequen-
cies, you may occasionally notice interference
from adjacent stations. To provide better per-
formance under these conditions, the RT-1080
allows you to reduce the range of frequencies
to either side of the precise tuned frequency,
thus reducing inter-station interference. Press
the FM IF NARROW button to use this feature.
A NARROW indication will appear in the
display. Press the button again to toggle back
to normal operation.
ANT A/B Button
As described in the REAR PANEL CONNEC-
TIONS section of this manual, the RT-1080 pro-
vides two FM antenna connections, labeled
A and B. This button toggles between the two
antenna inputs. An A or B indicator will ap-
pear in the display, indicating which FM an-
tenna input is active.
