ADJUSTMENTS
The only adjustment that should be
made to the FSK Expansion modem is
the output level. VR2 potentiometer
(labeled AMP) is used to make that
adjustment. The Audio output must be
loaded with 600 Ohms and the output
level measured across the 600-Ohm
resistor. You have an adjustment
range from –8 to 0 dBm.
The two other potentiometers on the
board should not need adjustment for
the life of the modem and require
special equipment to set correctly.
Contact the factory if you feel these
need adjustment.
