Rating
Adjust so that the meter is
maximum.
CAUTION: Over-adjustment of
the IFT core will reduce the
sensitivity. (Maximum±90°)
–43dB or less
–33dB or less
STEREO indicator
should light.
1) Set the tuning mode to
MAN'L MONO.
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 4dBµ or less.
(B, G only : 8 dBµ or less)
With SSG output at L or R, the
signal leakage level at the other
channel should be minimized.
