(2) FM center meter
Receive
a
broadcast
by
using
the
function
of
‘AUTO
STOP’.
Adjust
T105
(detector
coil)
so
that
the
voltage
at
TP102
becomes
0£1.5mV.
(T106
is
used
to
minimize
the
distortion
of
output
on
the
production
line.)
(3) FM separation
Receive a stereo signal.
Adjust
VR
167
so
that
channel
separation
becomes
maximam.
(4) MW Tracking
Adjust
T101
(antenna
coil)
to
obtain
the
best
receiving
sensitivity
on
600kHz
or
603kHz.
Adjust
TC105
(antenna
trimmer)
to
obtain
the
best
receiving
sensitivity
on
1400kHz
or
1404kHz.
(5) LW Tracking
Adjust
T102
(antenna
coil)
to
obtain
the
best
receiving
sensitivity
on
164kHz.
Adjust
TC106
