Tuner Operation

Basic Tuner Operation

The AVR’s tuner is capable of tuning AM, FM and FM Stereo broadcast stations and receiving 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 I on the

remote or hold the Band Selector ! on the front panel pressed for 3 seconds to select manual or automatic tuning.

When the button is pressed so that AUTO appears in the Main Information Display ˜ each press of the Tuning Selectors )K will put the tuner in a scan mode that seeks the next higher or lower frequency station with accept- able signal strength. An AUTO ST TUNED indication will momentarily appear when the sta- tion stops at a stereo FM station, and an AUTO TUNED indication will momentarily appear when an AM or monaural FM station is tuned. Press the Tuning buttons again to scan to the next receivable station.

When the button is pressed so that MANUAL appears in the Main Information Display ˜ each tap of the Selector will increased or decrease the frequency by one increment. When the tuner receives a strong enough signal for adequate reception, MANUAL TUNED will appear in the Main Information Display ˜.

4.Stations may also be tuned directly by pressing 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 automati- cally be tuned after the latest number is entered. If you press an incorrect button while entering a

direct frequency, press the Clear button

to

start over.

 

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 I on the remote or holding the Band Selector ! on the front panel so that MANUAL appears momentarily in the Main Information Display ˜ and then goes out.

Preset Tuning

Using the remote, up to 30 stations may be stored in the AVR’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 two underscore lines will appear in the Main Information Display ˜.

2.Within five seconds, press the Numeric Keys H 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 H 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 # on the front panel or remote.

RDS Operation

The AVR 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 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 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 (FREQ).

The Program Type (PTY) as shown in the list below.

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 TEXT will flash in the Information Display when RT is selected.

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 TIME will flash 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 Main Information 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.
