There are several revisions to the Delta-S and Delta-SX TRS boards; the
component labels and locations may be different than shown in your manual.
The voice deviation pot should be hidden under the shield covering up the
synthesizer/TRS area of the board (the rear compartment as viewed with front
of the radio toward you). The pot is accessible through a hole in the
shield. It's along the edge of the compartment closest to the front of the
radio, a little right of center. The pot is adjusted with a hex diddle
stick. Usually these pots have either a white or red plastic cap on them
(similiar to the pots used for setting the level of volume-squelch high, and
for setting power output in the PA); you should be able to see it through
the shield cover if you look with a flashlight.
There is also a pot for modulating the VCO (for low frequencies/DPL), which
is in the upper-right, but shouldn't normally need to be adjusted unless
you're using DPL, in which case, follow the procedure in the manual.
