CAUTION

Follow established standing operating procedures at all times, and use

the supplied test piece to confirm that the detector registers a correct

signal before and after every use. An area that has just been checked

with the F1A4 detector should not be considered safe until the detector

has been rechecked with the test piece.

a. Ensure that the detector is emitting the correct threshold tone. If in

doubt, perform Noise Cancel or Audio Reset procedure.

b. Make sure your hands and wrists are free of any metallic objects.

c. Place the test piece with the end with the hole lightly against the

centre of the bottom of the coil.

d. Confirm that a distinct signal is registered as the test piece is

moved in the directions shown in Figure 12.
