• Repeat the procedures in each adjustment several times, and the

frequency coverage and tracking adjustments should be finally
done by the trimmer capacitors.

• This adjustment should be executed after MW band adjustment

is completed because the LW and SW bands use the BAR ANT
and CV1 in common with the MW band.
Therefore, if MW band is adjusted, the LW and SW bands must
also be readjusted.

• Preparation for SW band adjustment

After making sure that the MW band adjustment has completed,
set the pointer to the center of character of 6.0, 7.2, 11.8 or
21.6MHz which is reference position of dial character, and fix
the CV1 at this position.
