Do not operate detector unless yellow with black stripe output amplifier module is
installed. Output amplifier modules other than the yellow with black stripe may not
alert the operator of low battery voltage. Detectors operated with low battery
voltage will not detect metallic objects, which endangers the life of the operator.
Check that modules are installed per the colors shown in figure 2-6. (The ouput amplifier module should be yellow with a
black stripe). If any module is missing, or the colors are out of sequence turn the detector in through normal maintenance
channels for repair. Users are not to change modules as it can affect the set's calibration. Repairs should be done by authorized
Do not operate the mine detector set prior to performing sensitivity check. Faulty
signal responses or other indications of improper operation endangers the life of the
