Scanning will not stop for broadcasts weak enough to be
suppressed by the muting circuit. To receive a weak FM
broadcast, set the FM mute/mode switch to the OFF
(MONO) position and tune in the FM broadcast using the
manual tuning mode.
On the TX-37, an FM tuning level switch. [15] permits the
muting level to be switched between high and low. In the high
position, scanning will only stop for strong stations; in the low
position, scanning will also stop for relatively weak stations.
For even weaker stations, set the FM mute/mode switch
to the OFF(MONO) position (in which case even stereo broad-
casts will be heard in mono).
