ADJUSTMENTS
POTENTIOMETER ADJUST MODE
The System Module contains up to 13 digital potentiome-
ters (10 in MASTR IIe applications) to set various operational
levels. These potentiometers must be adjusted properly to
ensure optimum station performance. The potentiometers,
their key, and function are listed on one of three pot pages. The
pages and associated potentiometers are listed below. Page 3
applies to MASTR III only. The adjustment range for each
potentiometer is given in Table 1.
