Tips for Better FM ReceptionThis 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 manually1Press MENU.
2Turn 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.
3Turn TUNING/SELECT to choose ATT/IF BAND and press ENTER.
4Turn 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.
5Turn 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 (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.) The
