d. Earset Socket.
•
The F3 has an internal speaker located inside the Handle.
However, the F3 can also be fitted with an Earset via the Earset
Socket. The procedure for connecting the Earset is described at
Section 2.3.h.
•
A standard humanitarian demining Earset (Earset Speaker On)
permits the F3's internal speaker to continue to function even
when the Earset is connected.
• • • •
For military countermine applications, an Earset that mutes the
F3's internal speaker when the Earset is connected is available
(Earset Speaker Off). The Earset Speaker Off is identified by a
short length of green tubing located at the rear of the Earset
plug.
Minelab strongly recommends that an operator should
always wear an Earset when using the F3 detector.
3.2 Sensitivity Endcaps. A unique feature of the F3 is its
ability to change sensitivity through the exchange of Sensitivity
Endcaps. This design feature eliminates the possibility of an
operator selecting the wrong sensitivity through manipulation of dials
or switches. The Sensitivity Endcap provides an obvious visual cue
that confirms the level of sensitivity selected in the F3. The F3 is
supplied with Black and Red Sensitivity Endcaps.
•
Black Sensitivity Endcap. With the Black Sensitivity Endcap
fitted, the F3 performs at maximum sensitivity.
Endcap MUST be selected when searching for minimum metal
mines or when maximum clearance depth is required.
