Minelab MF5 Operation Manual page 16

NOTE: After switching on the MF5,
when selecting IED or Conventional
Operations for the first time, a Ground
Balance procedure should be completed.
Provided the detector software is not
upgraded, subsequent selections of IED
or Conventional Operations do not require
another Ground Balance.
When the detector is switched off, Ground
Balance profiles for IED and Conventional
Operations are retained.
When conducting the Test Piece
procedure, select sensitivity Level 3 in
either IED or Conventional Operations.
Warning: When detecting targets
with low metal signatures, the
sensitivity level must not be lower
than Level 3 in either IED or
Conventional Operations.
6. Noise Cancel Button
Noise Cancel should be conducted whenever
the MF5 receives interference from electrical
sources such as power lines, generators or
other detectors operating in close proximity.
7. Target Alert Responses
An Operator can be alerted to a target by
audio, visual (LED), or haptic (vibration)
responses. All three alert responses can be
enabled or individually selected by the Operator.

8. Tactical Mode
The Operator has the option of selecting
Tactical Mode at anytime during the operation
of the MF5 or when the detector is switched
ON. Tactical Mode provides a vibration alert
response which can be deselected if required.
In Tactical Mode, the LED display is changed to
IR for use with night vision goggles.
NOTE: For safety purposes it is impossible
to disable all three target alert responses
simultaneously.
It is recommended that the audio alert
response be enabled at all times unless
the tactical situation dictates otherwise.
9. Battery Alarms
The MF5 battery status can be checked
at anytime (see Additional Functions on
page 17). Warning will be provided to the
Operator whenever the following
conditions occur:
• Low Battery Alert: When using NiMH
batteries a Low Battery Warning will occur
when approximately 30 minutes of NiMH
battery life remains. The alarm, via the
enabled alert responses, will be provided
every 45 seconds. During this period,
the MF5 will continue to function within
operational limits.
• Critically Low Battery Warning: Continuous
alarm via the enabled alert responses and
the MF5 can no longer be used.
• Battery Shutdown: The MF5 is shut down
due to lack of battery power.
Warning: Once the Low Battery
Warning occurs, batteries
should be replaced immediately
or as soon as possible before
the Critically Low Battery
Warning occurs.
