2.6 Detector Locking Mechanism
2.6.1 Detector Base
In the detector base a small locking nub will keep the springloaded
tongue in an open position to prevent the detector head from being
locked. If the locking nub is removed before mounting with a pair of
cutting nippers or similar, the detector head will enter a locked
position.
