Tuner Operation
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
1.Press the AM/FM Tuner Select button 6 on the remote to select the tuner as an input. The tuner may be selected from the front panel by either pressing the Input Source Selector % until the tuner is active or by pressing the Tuner Band Selector ! at any time.
2.Press the AM/FM Tuner Select button 6 or Tuner Band Selector ! again to switch between AM and FM so that the desired frequency band is selected.
3.Press the Tuner Mode button Ion the
remote or hold the Band Selector ! on the front panel pressed for 3 seconds to select manual or automatic tuning.
When the AUTO indicator Jis illuminated in the Main Information Display ˜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 ) K. When the AUTO indicator J is illuminated, press the button to cause the tuner 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 AUTO indicator J is not illuminated, tap the Tuning button ) Kto advance one frequency increment at a time, or press and hold it to locate a specific station. When the TUNED indicator I illuminates, the station is properly tuned and should be heard with clarity.
5.Stations may also be tuned directly by press- ing the Direct button J, and then pressing the Numeric Keys Hthat 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
NOTE: When the FM reception of a stereo station is weak, audio quality will be increased by switching to Mono mode by pressing the Tuner Mode button Ion the remote or hold- ing the Band Selector ! on the front panel pressed for 3 seconds until the STEREO H and AUTO J indicators go out.
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 on the remote. Note that MEMORY indicator G will illuminate and flash in the Main Information Display ˜.
2.Within five seconds, press the Numeric Keys Hcorresponding 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 Hthat correspond to the desired station’s memory location.
•To manually tune through the list of stored preset stations one by one, press the Preset

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 ^ 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 Pwill 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 CT Indicator O will illuminate when time
