*:Execution of PRESET (Refer to page 27.) will facilitate setting reception frequency for adjustment.
Rating
Adjust so that the DC voltage
is maximum.
CAUTION : Over-adjustment
of the IFT core will reduce the
sensitivity.
Maximum ±90°
0.4% or less
1% or less
• STEREO indicator should
light.
1)Set the tuning mode to
MAN’L MONO.
(Muting OFF)
2) S/N should be 30dB at each
frequency of 88.1MHz,
98.1MHz, and 106.1MHz.
3)Check to ensure that the
voltage at the ANT terminal
is 5dBµ or less.
(A only : 7dBµ or less)
With SSG output at L or R, the
signal leakage level at the
other channel should be mini-
mized.
35dB or more
Adjust so that all segments
light.
Check to ensure that signal
meters turn OFF.
• Automatic reception
should be available when
the tuning key is moved UP
and DOWN.
• The stereo indicator should
light.
• Audio muting should be ap-
plied during tuning.
