OPERATION
uSInG tHe tuner
To select the AVR 760/AVR 660’s built-in tuner:
Press the Source List Button on the front panel. Use the
1.
KL
Buttons to
scroll to the desired tuner band.
Press the Radio Source Selector on the remote. Press it again to switch
2.
bands (AM or FM).
A screen similar to the one shown in Figure 25 will appear.
Figure 25 – FM Radio
Use the
KL
Buttons or the Channel Control to tune a station, as displayed
on the front panel and on screen.
The AVR defaults to automatic tuning, meaning each press of the
KL
Buttons scans through all frequencies until a station with acceptable signal
strength is found. To switch to manual tuning, in which each press of the
KL
Buttons steps through a single frequency increment (0.1MHz for FM, or
10kHz for AM), press the Menu Button. The Mode line will display the current
setting. Each press of the OK Button toggles between automatic and manual
tuning modes.
When an FM station has been tuned, toggling the tuning mode also switches
between stereo and monaural play, which may improve reception of weaker
stations.
A total of 30 stations (AM and FM together) may be stored as presets. When
the desired station has been tuned, press the OK Button, and two dashes
will flash in the front-panel display. Use the Alphanumeric Keys to enter the
desired preset number.
To tune a preset station, press the
M N
Buttons or the
I J
Transport
Controls, or press the Menu Button and scroll to the desired preset, then
press the OK Button; or enter the preset number using the Numeric Keys. For
presets 10 through 30, press 0 before the preset number. For example, to
enter preset 21, press 0-2-1.
rDS operation
The AVR 760/AVR 660 is equipped with RDS (Radio Data System), which
brings a wide range of information to FM radio. Now in use in many countries,
RDS is a system for transmitting station call signs or network information,
a description of station program type, text messages about the station or
specifics of a musical selection, and the correct time.
As more FM stations become equipped with RDS capabilities, the AVR will
serve as an easy-to-use center for both information and entertainment. This
section will help you take maximum advantage of the RDS system.
RDS Tuning
When an FM station is tuned in and it contains RDS data, the AVR will
automatically display the station’s call sign or other program service in the
Message Display and on the tv screen if this is on.
RDS Display Options
The RDS system is capable of transmitting a wide variety of information
in addition to the initial station call sign that appears when a station is
first tuned. In normal RDS operation the display will indicate the station
name, broadcast network or call letters. Pressing the Play Button
B
on the
Remote enables you to cycle through the various data types in the following
sequence:
The station’s call letters (PS) (with some private stations other information
•
too).
The station’s frequency (FREQ MODE), which is always shown on the TV
•
On-Screen Display, is shown in the Message Display.
The Program Type (PTY).
•
NOTE
: Many stations do not transmit a specific PTY. The display will show
NONE, when such a station is selected and PTY is active.
A “text” message (Radiotext, RT) containing special information from the
•
broadcast station. Note that this message may scroll across the display to
permit messages longer than the eight positions in the display. Radiotext
is not shown on the TV On-Screen Display.
The current time of day (CT). Note that it may take up to two minutes
•
for the time to appear, in that time the letters CT are shown in the
information display when CT is selected. Please note that the accuracy of
the time data is dependent on the radio station, not the AVR.
Some RDS stations may not include some of these additional features. If the
data required for the selected mode is not being transmitted, the Message
Display will show a NO TYPE, NO TEXT or NO TIME message after the
individual time out.
In any FM mode the RDS function requires a strong enough signal for proper
operation.
Program Search (PTY)
An important feature of RDS is its capability of encoding broadcasts with
Program Type (PTY) codes that indicate the type of material being broadcast.
You may search for a specific Program Type (PTY) by following these steps:
Press the Play button
1.
B
until the current PTY is shown in the Main
Information Display.
While the PTY is shown, press the CH/Page Up/Down or the
2.
M N
Buttons
or hold them pressed to scroll through the list of available PTY types, as
shown above starting with the PTY currently received.
Press either of the
3.
KL
Buttons. The tuner begins to scan the FM band
upwards or downwards for the first station that has RDS data that
matches the desired selection, and acceptable signal strength for quality
reception.
The tuner will make up to one complete scan of the entire FM band for
4.
the next station that matches the desired PTY type and has acceptable
reception quality. If no such station is found, the display will read NONE
for some seconds and the tuner will return to the last FM station in use
before the search.
