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.
Selecting FM aerials
When you use two FM aerials, press ANTENNA to
select FM ANTENNA terminal A or B. By selecting the
aerial, you may be able to receive a station that cannot
be received otherwise.
Changing the Active Selection Mode (ASM)
This tuner's Active Selection Mode (ASM) is factory
preset to find the best antenna attenuator (ANT ATT),
intermediate frequency band (IF BAND), and FM
MODE settings for each frequency automatically. You
can, however, choose each setting manually according
to your preference. If you don't want to use the ASM
function, turn it off.
1 Press MENU.
2 Turn TUNING/SELECT until “Reception”
appears in the display and press ENTER.
3 Turn TUNING/SELECT to choose “A.S.M.” and
press ENTER.
4 Turn TUNING/SELECT to choose “A.S.M.: OFF”
or “A.S.M.: ON” and press ENTER.
When ASM is turned on, the ASM indicator
appears in the display when you select the FM
band.
To set the ANT ATT and IF BAND manually
1 Press MENU.
2 Turn TUNING/SELECT until “Reception” appears in the
display and press ENTER.
“FM Only” appears in the display if you choose
“Reception” while tuned to an MW or LW station.
3 Turn TUNING/SELECT to choose ATT/IF BAND and
press ENTER.
4 Turn TUNING/SELECT to choose the ANT ATT setting
you prefer and press ENTER.
• “ANT ATT : ON” lowers the level of the input signal to
receive broadcasts with extremely high signal levels.
• “ANT ATT : OFF” is for normal tuning.
5 Turn TUNING/SELECT to choose the IF setting you
prefer and press ENTER.
• “IF : Wide” tunes only the stations with high sound
quality and low distortion.
• “IF : Narrow” improves selectivity and reduces
interference to make broadcasts with weak signals
easier to listen to.
To set the FM mode manually
Press FM MODE a few times to choose the reception mode,
select either Auto stereo (no indication), HI-BLEND, or
MONO.
• Auto stereo mode receives stereo broadcasts with strong
signals. Press FM MODE until both “HI-BLEND” (“BLN”
for ST-SA3ES) and “MONO” disappear.
• “HI-BLEND” (“BLN” for ST-SA3ES) reduces noise in the
high frequencies. You can receive stereo broadcasts with
less noise, but the stereo sound quality will be slightly
diminished.
• “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 of the
digital meter is from 16 to 70 dB (1µV of radio
frequency voltage = 0dB). 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 aerial to obtain the strongest signal.
