The signal strength meter on the left side
of
the display indicates the relative
FM
signal strength
being received by the GFT-555. The higher the number
of
steps reached on the 5 step ladder
of
LEOs,
the
better the signal.
You
should orient your antenna so that the signal strength indicator reaches the highest
level
on your favorite
FM
stations.

band. Your selection is indicated on the Display.
MUTE/MONO
(L1
This switch is used to defeat the muting circuit of the GFT-555. During normal operation, the
GFT-555
utilizes a muting circuit to reduce interstation noise which occurs
as
you tune from station
to
station on the FM band. The muting circuit, which is normally engaged, will not allow very weak stations
to
be
received. Should you desire
to
receive a weak station, simply depress the Mute/Mono switch
to
defeat the muting circuit. This will allow weak stations to
be
received in the Mono mode, which provides
the added benefit
of
eliminating much
of
the background noise common in weak stereo
FM
signals.
