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 (ST-SE700 only)
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)
(ST-SE700 only)
This tuner's Active Selection Mode (ASM) is factory
preset to find the best aerial 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.
Press ASM to turn the active selection mode off or on.
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.
Advanced Tuner Operations
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.
Setting the FM mode manually
Press FM MODE a few times to choose 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.)
The ST-SE700 also lets you use the digital signal meter
with the AM band. With AM, display range is from 0
to 15 (larger values indicate stronger signals).
1 Tune in an FM or AM (ST-SE700 only) station.
2 Press DISPLAY repeatedly to display the digital
signal meter.
3 Rotate the FM or AM (ST-SE700 only) aerial to
obtain the strongest signal.
