Minelab MF5 Operation Manual page 15

1. LED Display
A display of nine LED provides a visual
indication of detection signal strength when in
Detection and Pinpoint Modes and information
regarding target composition when in
Interrogation Mode.
2. Ground Balance Button
Ground Balance should be conducted every
time the MF5 is switched ON and when first
changing between IED and Conventional
Operations or vice versa. The automated
Ground Balance procedure removes
interference or false alarms from mineralised
soils and rocks whilst maintaining sufficient
sensitivity to detect targets of interest.
NOTE: Whenever the MF5 is restarted,
the previous Ground Balance condition is
retained although a new Ground Balance
is recommended.
3. Mode Button (Yellow)
The MF5 operates in one of three
sensor modes:
• Detection Mode: Detection Mode is
the default sensor mode to be used for
detecting all targets. It is the most
sensitive mode.
• Interrogation Mode: By pressing and
releasing the Mode Button once, the MF5
will enter into Interrogation Mode which
provides additional target information to
the Operator.
• Pinpointing Mode: By pressing and
holding the Mode Button, the MF5 will
enter Pinpointing Mode, which assists the
Operator to accurately map and pinpoint the
target. When the Mode Button is released,
the MF5 will revert to Detection Mode.
4. Power Button
To switch the MF5 ON or OFF, Long Press
(> 0.5 s) Power Button. The MF5 will complete
start-up procedures and internal diagnostics to
ensure the detector is operational and working
within design parameters. By default, the MF5
will commence in Detection Mode and emit a
double-tick heartbeat every 15 seconds.
5. Sensitivity Knob
The MF5 can be operated in one of five
sensitivity levels in either Conventional or IED
Operations. To select a sensitivity level, the
Sensitivity Knob must first be lifted slightly and
then rotated.
The need to first lift the Sensitivity Knob
prevents accidental or inadvertent changes to
sensitivity without the Operator's knowledge.
• IED Operations (Default): IED Operations
should be selected when searching for all
types of targets including carbon rods and
fine wires.
• Conventional Operations: Conventional
Operations result in the MF5 being less
sensitive to carbon rods and wires and is
most suitable for the detection of metal
contained in conventional ordnance or
landmines. Conventional Operations is also
more effective when searching in ground
with high salt content; for example
beach areas.
After switching on the MF5 in IED or
Conventional Operations a Ground Balance
procedure must be conducted.
