Tips for better FM
reception
This tuner has various functions designed for
better reception. First, try to receive stations
with the standard settings. If the reception is
not good, try altering the reception quality to
obtain a clear signal. The tuner stores the
following adjustments, together with the
frequency when you make a station preset.
Setting the FM mode
Press FM MODE a few times to select the
reception mode, select either Auto stereo (no
indication) or “MONO”.
Auto stereo mode receives stereo broadcasts
with strong signals. Press FM MODE a few
times so that “MONO” disappears.
“MONO” receives stations with weak signals.
Stations will be received in monaural but with
even less noise.
Checking the signal strength
You can use the digital signal meter to check
the signal strength of FM frequencies. The
display range is from 16 to 70 dB (1 µV of
radio frequency voltage = 0 dB). To obtain a
signal to noise ratio sufficient for receiving a
stereo broadcast, we recommend a reading
greater than 50 dB. (You can also change the
FM MODE while using the signal meter to
determine the best reception.)
1 Tune in an FM station.
2 Press DISPLAY repeatedly to display
the digital signal meter.
3 Rotate the FM antenna to obtain the
strongest signal.
Receiving broadcasts by
scanning stations (Automatic
Tuning)
With automatic tuning, you can quickly tune in
a station without having to know its frequency.
1 Press BAND repeatedly to select either
FM or AM (MW and LW).
2 Press TUNE MODE so that “AUTO
TUNING” (“AUTO” for ST-SE370)
appears in the display.
3 Turn TUNING/SELECT slightly and
release it when the frequency numbers
start changing.
Turn the control to the right for a higher
frequency; turn it to the left for a lower frequency.
When the tuner locates a station, it stops
automatically. “TUNED” appears in the display.
The signal meter indicates the strength of the
broadcast signal.
4 Repeat step 3 until you tune in the
appropriate station.
To store the station, see “Presetting radio
stations” on page 8.
If you cannot tune in the station you
want (Manual Tuning)
With manual tuning, you can search through all
stations broadcasting on each band, and tune in
stations with extremely weak signals that you might
not be able to receive with automatic tuning.
1 Press BAND repeatedly to select FM or AM
(MW and LW).
2 Press TUNE MODE so that only “TUNING”
appears in the display (ST-SE570 only).
“AUTO” should not appear in the display.
For ST-SE370, press TUNE MODE until
nothing appears in the display.
3 Turn TUNING/SELECT until you tune in the
station you want.
Turn the control to the right for a higher
frequency; turn it to the left for a lower frequency.
The signal meter indicates the strength of the
broadcast signal.
Note
When you reach the highest or lowest frequency of
any band, tuning stops.
