The muting circuit is designed to remove the typical FM
interstation noise generated when moving away from in-tune
frequencies, but it can also prevent reception of distant or weak
signal stations. In this case, press the MUTING switch off and
tune into the desired station. Normally, leave this switch on
(MUTING indicators lit).
This switch does not affect AM reception.
NOTE:
The setting of this switch is memorized together with the
station in the station memory.
