RX-975 AM/FM Stereo Receiver
Tuning Controls
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.
