Overview

Potentiometer PT3 – The analog input circuit contains an AGC gain amplifier. The

gain of this amplifier is adjusted by PT3. To use the AGC gain amplifier, the shunt

plug on 201358-01 site J4 must be moved from the “Bypass” position (factory

setting) to the “Gain” position. Refer to the A/D Calibration section of General

Dynamics Document #CG-0283.
