Basic Tuner Operation
The AVR 5550’s tuner is capable of tuning AM,
FM and FM Stereo broadcast stations and receiv-
ing RDS data. Stations may be tuned manually, or
they may be stored as favorite station presets and
recalled from a 30 position memory.
Station Selection

the tuner will
only stop at those stations that have a strong
enough signal to be received with acceptable
quality.
When the AUTO indicator
J
is not illuminated,
the tuner is in a manual mode and will stop at
each frequency increment in the selected band.
4.To select stations press any Tuning button

to search for the next highest or lowest frequen-
cy station that has an acceptable signal or hold
the button pressed to tune fastly and release it
to start the auto search. In the Auto mode the
tuner will play each station in stereo or mono
mode, just as the program is transmitted. If the

5. Stations may also be tuned directly by press-
ing the Direct button
J
, and then pressing
the Numeric Keys
H
that correspond to the
station’s frequency. Note that for entering num-
bers higher than 100 you need to enter only the
"1" rather than "10", the first "0" will be
added automatically. The desired station will
automatically be tuned after the latest number is
entered. If you press an incorrect button while
entering a direct frequency, press the Clear
button

Preset Tuning
Using the remote, up to 30 stations may be
stored in the AVR 5550’s memory for easy recall
using the front panel controls or the remote.
To enter a station into the memory, first tune the
station using the steps outlined above. Then:
1. Press the Memory button
Y
on the
remote. Note that MEMORYindicator
G
will
illuminate and flash in the Main Information
Display

.
2.Within five seconds, press the Numeric
Keys

corresponding to the location where
you wish to store this station’s frequency. Once
entered, the preset number will appear in the
Main Information Display

.
3. Repeat the process after tuning any additional
stations to be preset.
Recalling Preset Stations
• To manually select a station previously entered
in the preset memory, press the Numeric Keys

that correspond to the desired station’s
memory location.
• To manually tune through the list of stored
preset stations one by one, press the Preset
Stations Selector buttons

front panel or remote.
RDS Operation
The AVR 5550 is equipped with RDS (Radio Data
System), which brings a wide range of informa-
tion 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 5550 will serve as an easy-
to-use center for both information and entertain-
ment.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 RDS Indicator
G
will illuminate,
after some time also the indicators for all other
RDS services received (see below), and the
AVR 5550 will automatically display the station’s
call sign or other program service in the Main
Information Display
˜
.
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
RDS button
^
V
enables you to cycle
through the various data types in the following
sequence:
• The station’s call letters (with some private
stations other information too).
• The station’s frequency.
• The Program Type (PTY) as shown in the list
below. The PTY Indicator
P
will illuminate
when this data is being received.
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. Depending on signal
quality, it may take up to 30 seconds for the text
message to appear; in that time, the word
TEXTwill flash in the Information Display when
RT is selected. The RT Indicator
R
will illumi-
nate when text data is being received and ready
to be displayed.
• The current time of day (CT). Note that it may
take up to two minutes for the time to appear,
in that time the word TIMEwill flash in the
information display when CT is selected. The
CTIndicator
O
will illuminate when time
