REMARKS :

1) When aligning FM IF , the symmetrical curve may not be obtained by setting the marker

of the Sweep Generator (10.7 MHz ). This is due to the ceramic filter used in the until.

Regardless of the marker, align the curve as symmetrically as possible with peak output.

2) When aligning the Tuning Range and adjusting the Tracking , proceed with alignment in a

sequence of FM - AM

3) Use a screwdriver with a plastic grip for all alignments .
