Sensitivity Knob - Minelab F3 Compact Operation Manual

During operation, continuous internal self-testing continues and an alarm tone
is triggered on detection of any fault condition (refer to "Functional Tones" on
page 20 for a description of the alarm tones).
To turn the F3 Compact off, pull out the On/Off Knob and rotate counter-clockwise
to the Off position. Release the switch back to the locked position.

Sensitivity Knob

The F3 Compact can be operated using seven preset sensitivity settings. Position
4 is the default position and should always be selected when switching on the
detector and conducting the Test Piece procedure (refer to "STEP 3 Test Piece" on
page 25).
The Yellow Dot on the decal indicates the position that, when selected, permits
the detector to be customised for specific Sensitivity selections. To customise
the detector, Minelab supplied configuration software and cables are required. The
detector is shipped with a factory preset for the Yellow Dot selection; this makes
the detector operate the same as the default Position 4.
When detecting targets with low metal signatures, the F3 Compact should not be
operated with a Sensitivity setting lower than the default setting (Position 4). Where
possible, Free From Explosive targets should be buried at the required detection
depth. Sensitivity options (Positions 4 to 7) should then be tested to determine the
most suitable sensitivity to ensure detection of the target.
