Sensitivity Knob - Minelab F3 COMPACT Operation Manual

F3 COMPACT Operations Manual
On completion of the Start-Up Tones the F3 COMPACT emits a low
steady tone known as the Threshold Tone, which confirms to the
operator that the F3 COMPACT is functioning correctly.
During operation, continuous internal self-testing continues and an
alarm tone is triggered on detection of any fault condition (refer to
section 3.2 for a description of the alarm tones).
To turn the F3 COMPACT off, pull up the On/Off Knob and rotate
counter-clockwise to the Off position. Release the switch back to the
locked position.

3.1.2 Sensitivity Knob

The F3 COMPACT can be operated using seven preset volume
and 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 section 4.2.3).
The Yellow Dot on the decal indicates the position that, when
selected, permits the detector to be customised for specific Volume
and 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 as if it was performing at a capability
greater than Position 4.
