Tuning Controls

RX-975AM/FM Stereo Receiver

The RX-975 features a digital synthesized AM/FM tuner with 30 station presets. Op- eration of the tuning functions involves the use of a row of numeric buttons and five large buttons below the MASTER VOLUME knob.

BAND Button

The BAND button selects whether the tuner is in AM or FM mode. Press the button to toggle back and forth between AM and FM. A corresponding indicator will light at the left portion of the front panel display to confirm your choice and the currently tuned station frequency will be shown.

TUNING Button

This rocker switch (or pair of buttons labeled CH UP/DOWN on the remote control) pro- vides two different tuning functions, depend- ing on the mode of operation.

In the normal FREQUENCY TUNING

mode, press a TUNING button and release to manually jump to the next station frequency, regardless of whether or not a station is broadcasting on that frequency. For auto scan tuning, press and hold the TUNING button for approximately one second. An AUTO in- dicator will appear in the front panel dis- play and the tuner will begin automatically scanning up or down through the frequen- cies until the next available station is detected. If this is not the desired station, repeat the automatic tuning procedure to find the next station. Weak stations will be skipped dur- ing auto tuning.

In the PRESET TUNING mode, press a TUNING button and release to jump to the next memorized station preset. Switch be- tween FREQUENCY and PRESET tuning modes by pressing the SHIFT button and then the BAND/TV button on the remote control. A PRESET indicator appears in the display when PRESET TUNING is activated.

NOTE: Several indicators in the front panel display assist tuning. A large display shows the tuned frequency and increases or de- creases during tuning. A TUNED indicator lights when a sufficiently strong signal is received. A ST indicator lights when a ste- reo FM signal is received.

NUMERIC Buttons: Station Presets

The RX-975 can store up to 30 station pre- sets for recall at any time using the NUMERIC buttons. To memorize a station:

1.Tune to the desired station, AM or FM.

2.Press the MEMORY button on the front panel. A MEMORY indicator will flash for five seconds in the front panel display.

3.While the MEMORY indicator is flashing, press the number of the preset where you wish to store the station frequency. For example, to memorize the station as preset 3, press the 3 button. To memo- rize preset 15, press the 1 button followed by the 5 button.

4.A previously stored frequency is erased from memory when a new frequency is memorized for the same preset number.

To tune to a previously memorized station, just press the preset number

on the NUMERIC buttons. For example, to tune to preset 3, press the 3 button. To tune to preset 15, press the 1 button and then press the 5 button.

NOTE: If the TUNER is not already the se- lected INPUT SOURCE, selecting a station preset will automatically switch to the TUNER input and tune the memorized sta- tion.

The NUMERIC buttons can also be used for direct access tuning (see below).

FREQUENCY DIRECT Button

If you know the frequency of the desired station, you may tune it directly using the FREQUENCY DIRECT button and the NU- MERIC buttons.

1.Press the FREQUENCY DIRECT button to change the NUMERIC buttons from sta- tion preset to Direct Access mode. The station frequency in the front panel dis- play will change to a series of four bars, representing the digits of a station fre- quency, with the first bar flashing.

2.Enter the first digit of the station frequency using the NUMERIC buttons. The digit will appear in the frequency display and the second bar will flash. Enter the remain- ing digits of the frequency. When all of the digits have been entered, the tuner will automatically tune to the displayed station frequency.

NOTE: On the USA version only, pressing 1 in the FM mode will enter 10 as the digit in the frequency display. On the Eu- ropean version, it is necessary to press 1 and then 0 to enter 10. For US FM sta- tions, press only one digit following the decimal point as shown in the first ex- ample below. For European FM stations, press two digits following the decimal point as show in the second example.

EXAMPLES:
(USA FM) 87.50MHz	Press 8>7>5
(Europe FM) 87.50MHz	Press 8>7>5>0
(all AM) 1610kHz	Press 1>6>1>0

MONO Button

The 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 sig- nal and there is sufficient signal strength. A stereo indicator will light in the front panel display. In mono mode, a mono signal will be heard even if the station is broadcasting a stereo signal.

NOTE: Switching to mono mode can be a useful way to improve the reception of weak or distant FM signals. Less signal strength is required for clean mono reception than for stereo reception.
