Table 43.
For I
(see
Level alignment should begin with slope alignment (LSL): the level slope does not change
with level start alignment (LST) or broadcast band; therefore a single LSL alignment
setting can be used for all FM and AM band selections.
Level start may change between broadcast bands; therefore generally a separate LST
alignment and setting is used for every broadcast band.
