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.
