  • Page 6 Functional testing is used to confirm the serviceability of an F3Ci before it is returned to the field for use and whenever doubt exists about its serviceability. The F3Ci must pass all tests to be considered serviceable and ready for use. Whenever a line replaceable unit is replaced or a repair is conducted, all functional testing must be completed.
  • Page 7 The noise cancelling procedure will commence with a single beep followed by 20 • seconds of sharp triple beeps and finish with a four beep sequence. During the 20 seconds the F3Ci scans the environment searching for the source of • any electrical interference. Once detected, the detector will automatically select a different operating frequency to eliminate or reduce the interference.

  • Page 61: Fault Finding Procedures

    A functional test failure can generally be repaired by replacing one or more of the line replaceable units. The F3Ci is designed so that line replaceable units can be exchanged between detectors without the need to calibrate. This means that where spare parts are not available and more than one detector is faulty, then parts from one detector can be used to make another serviceable.
