Programming the Audio Levels:
After determining the audio levels at the audio hookup points, it will be necessary to program the scrambler to
match these levels. In the programming software, there is a slider control on the Audio Levels Screen for each of
the of four audio hookup points. Locate the column that corresponds to the modulation and units of measurement
for each of the audio hookup points. Adjust the slider bar such that the value appearing in the appropriate column
matches what was measured as closely as possible.
