Hold the test piece above the middle of the coil with the metal end of the test piece away
•
from the coil.
Move the test piece towards the centre of the coil until it lightly touches the coil then
•
move it sideways off the coil.
Confirm a faint but clear response (detection tone) is heard.
•
If the test piece is not heard conduct an audio reset and repeat the test.
•
If the test piece is still not heard, refer to section 4 for the fault finding procedures.
•
The test piece test can only be conducted with the sensitivity control set to Sensitivity setting 4
(default setting marked with a green triangle). When the sensitivity control is not set to setting 4
it is the responsibility of the user to provide an appropriate target with which to confirm the
sensitivity of the detector satisfies operational requirements.
Provided the F3 COMPACT passes all function tests it is serviceable and ready for
l.
operations. The detector can now be packed into its bag ensuring batteries are removed and all
accessories are in place. If the detector does not pass all functional tests refer to section 4 for
fault finding procedures.
