4.3.6.1 A/D Circuit Calibration
A calibration procedure is performed at the factory as part of the normal product
configuration, therefore a field calibration is only performed if operational problems
due to drift are encountered at a later date or if different video receivers are used
in the AGC mode. Should field calibration be necessary, refer to General Dynamics
