NOTE
Electronics within the F3Ci ensure that its performance remains
consistent as the charge state of the batteries begins to reduce.
When the batteries can no longer supply the necessary power to
sustain correct performance of the detector, a Battery Low Alarm will
alert the operator.
* WARNING *
When Battery Low Alarm occurs the operator must immediately
STOP operations. The F3Ci should be switched off and new or
recharged batteries inserted into the Battery Compartment.
3.3 Test Piece – Functional Test
The F3Ci is supplied with a Test Piece designed to confirm that the
detector is working to correct specifications. The sensitivity of the
detector should be checked with the Test Piece when the Sensitivity
Knob is at Position 4 (default). In some instances, a user may prefer
to use inert mines or targets as test pieces because they represent
the local threat. Minelab recommends that the detector is always
first tested with the supplied Test Piece before local test pieces are
used for testing.
